    CASPOL & Add-in : How to Full trust the assemblies ?

    • 0 Comments

    If we want to "fully trust" the assemblies, it can be done through the signed assemblies. In Visual Studio 2005, you need to select the Properties for the project and select the Signing tab.  After you installed (including the newly signed assemblies) you need to give permission to the assemblies. This can be done using a tool called CASPOL.EXE.

    The CASPOL or Code Access Security Policy tool enables users and administrators to modify security policy for the machine policy level, the user policy level, and the enterprise policy level. For detailed information, you can have a look at the following article.

    Find the command line for registering your file: caspol -u -ag All_Code -url "<full path to your file>" FullTrust -n "<assembly name>"

    If you have more than one file or if you want to do this for a directory: caspol -u -ag All_Code -url "<directory path>\*" FullTrust

    Exchange Server 2003 & Public folders

    • 0 Comments

    Some organizations use public folders heavily, while others do not. The degree to which public folders are used in your organization may have a large effect on how you plan for migration and coexistence of public folders and the data stored therein. Factors to consider include:

    • The total number of public folders and the amount of data contained in them. Many organizations choose to remove unneeded folders from their public folder structure as part of their migration process.

    • The number of existing replicas and where they are located. Because Exchange public folders can be easily replicated between servers, many organizations have placed public folder servers at remote sites to improve access for remote users; as part of server consolidation, these replicas will normally be re-homed elsewhere.

    • The extent to which public folders are used as part of normal operations. If public folder-based applications are in use, how much are they used? Do users depend on them for their key tasks, or are they of secondary importance?

    • The messaging clients to be used after the consolidation. Outlook 2003 can be configured to cache users' public folder favorites; this makes public folder access in Cached Exchange Mode seamless, but it increases the size of the OST file, and it causes additional synchronization traffic. Requests for public folder items will be automatically directed to the best available replica, which may be in a distant site across a slow or high-latency link.  

    Even if your organization does not use public folders for business reasons, Exchange still uses two important system public folders that must be accounted for in your planning.

    First, the Schedule+ Free/Busy folder is where Exchange stores free/busy status for individual mailboxes. Outlook publishes users’ calendar status to this folder, as does the Exchange System Attendant.

    Having multiple replicas of this folder helps ensure quick and consistent access to schedule data throughout the organization; however, these replicas have to be synchronized, which can add a substantial amount of network traffic.

    When a user creates a new meeting request, Outlook opens a connection to find each attendee’s free/busy data. First, Outlook retrieves the user's legacy distinguished name, which it then uses to identify the name of the free/busy folder it needs. Outlook then searches for the correct folder and message for the specified user's schedule data. This means that a single meeting request may generate multiple un-cached connections to different servers.

    On the other hand, adding multiple replicas of the free/busy folder means that changes made to one replica may take time to propagate to other replicas. Adjusting the number of replicas, their location, and the replication schedule used may be necessary to ensure the right balance between minimized access time and replication convergence.

    Offline Address book is one of the advantage when you make use of public folder. The OAB provides offline and Cached Exchange Mode users access to a subset of properties for all objects in the global address list.

    Exchange generates updates to the OAB periodically, and Outlook automatically downloads available changes once a day (in online mode) or when the user goes online (in Cached Exchange Mode).

    In general, Microsoft’s normal recommendation is to maintain OAB replicas on each server that contains user mailboxes. As you consolidate user mailboxes, you should bear in mind that when the OAB changes, a large number of clients may need to download OAB changes at once, and plan network capacity and CPU allocation accordingly.

    Outlook UI Issue: Save password setting not retained ?

    • 1 Comments

    One of my customer uses MS Windows XP SP3 & Outlook 2007 reported that whenever he tries to connect to the Internet service provider (ISP) to retrieve messages from POP3, his earlier entered password is not retained. He was pretty sure that  he chose to save the password. Also he tried to entering the correct password again does not resolve the issue.

    This issue occurs for one or more of the following reasons:

    • You have a corrupted Outlook profile or a corrupted Outlook Express identity.

    • It may be due to the registry changes or corrupted information.

    • This issue might happen add-ins also.

    I used the following troubleshooting steps:

    Step 1: Check Outlook has valid profile or not.

    It's recommended to make use of new profile without any issues associated with that.

    After you locate the .pst files, create a new e-mail profile in Outlook. To do this, follow these steps.

    1.Start Outlook.

    2. On the Tools menu, click Account Settings.

    3. Click the E-mail tab, and then click New.

    4. Follow the instructions in the Add New E-mail Account wizard to create the new account.
    Note If you do not have the account information that the Add New E-mail Account wizard requires, view the settings for your existing account. To do this, click the account on the E-mail tab in the Account Settings dialog box, and then click Change. Note each setting in the Internet E-mail Settings dialog box.
    If you do not know the password for your e-mail account, contact your Internet service provider (ISP). Or, if your mailbox is not associated with your ISP, contact the network administrator of the server on which your mailbox is located for help with your password.

    Step 2: Open the Outlook in safe mode

    This will avoid any add-ins getting loaded and creating the issues

    1. Click Start, and then click Run.

    2. In the Open box, type outlook.exe /safe, and then click OK.

    Step 3: Troubleshooting with COM Add-in

    To troubleshoot possible problems that are caused by COM add-ins, disable any COM add-ins that you do not use regularly. Then, restart Outlook. If that does not resolve the problem, disable the add-ins one by one. If that does not resolve the problem, disable all add-ins. To disable COM add-ins, follow the steps for the version of Outlook that you are using.
    For Outlook 2007
    To disable COM add-ins, follow these steps:

    1. On the Tools menu in Outlook 2007, click Trust Center.

    2. Click Add-ins, click COM Add-ins in the Manage list, and then click Go.

    3. In the COM Add-Ins dialog box, click to clear the check boxes for any COM add-ins that you want to disable.

    4. After you disable the add-ins, click OK, and then restart Outlook.

    Monitoring event sink # 22 - Store Event sink registered with Outbox or Sent item folders won’t fire

    • 1 Comments

    Have you register an Exchange 2000 store event sink globally on the mailbox store, the sink fires for the appropriate events (OnSyncSave, for example) for all folders in a mailbox. However, the sink does not fire for events in the Outbox or the Sent Items Folder?

    For example, when a user sends an e-mail, it appears in the Outbox folder for a brief time.

    Outbox: This is due to Even if an event sink is registered directly on the Outbox, it will not fire.

    The Outbox is a temporary home for a new message while it waits to be picked up by the MAPI spooler. When the message appears in this folder, it does not generate an OnSave or OnSyncSave event. Also, when the message disappears from the folder, it does not generate an OnDelete or OnSyncDelete event.

    Sent Items:
    Messages are moved to the Sent Items folder after being sent by the MAPI client in such a way that events are not generated, and this behavior is by design. The appropriate events are generated if you manually move items into the Sent Items folder.

    Please find the following KB article, which provides resolution.

    Public folder support for Exchange Server 2007 till 2016 ?

    • 0 Comments

    I went through the following Technet article which talks about one such a interesting question of my favortie "What is happening with public folders ?"

    Please find the excerpts "...Exchange 2007 de-emphasizes public folders. Public folders may not be included in future releases, but support for public folders will be maintained through at least 2016. Current Microsoft Exchange customers should plan to migrate to Outlook 2007 and Exchange 2007. We recommend that you investigate integrating Microsoft Windows SharePoint Services with Exchange Server 2007 if you must have an application that supports sharing documents, calendar items, contacts, and tasks and archiving distribution lists. For other customized applications that are being developed, you should use Microsoft .NET .."

    Programming technology options for you with Exchange Server 2003

    • 1 Comments
    image

     

    Please find the following MSDN article, which describes, the list of programming technologies, that can be helpful to apply in Exchange Collaborative applications.

    Some of the of technologies available: ADO, ADSI, CDO, EXOLEDB, LDAP, MAPI, Schema, Search, Store Events, WebDAV, Webforms, WMI Providers.


    ADO:

    ActiveX Data Objects (ADO) are used to navigate through Web Storage System. ADO allows the developer to access all Microsoft Database APIs, as well as search for and bind objects. ADO contains built-in objects that the developer can use to add features to the application. This permits developers to add dynamic objects to a static Web page.

    ADSI:

    ADSI is a standard Windows-based interface for meta-directory applications. A meta-directory is a high-level network directory service designed to unite account and resource information from multiple network operating environments. The goal of ADSI is to synchronize this information across differing directories. Meta-directories extract security and account data from each directory, and then manage this information as part of an external database.

    ADSI is comprised of a series of client-side DLLs that provide a common set of directory management functions. You can access these functions from almost any environment. As a result, you can add or remove user accounts, configure shared resources, and browse the directory tree all from a single, integrated console. Exchange 2000 uses ADSI to integrate application services with Active Directory's security and account functions. You can also access ADSI using Microsoft Visual Basic, Scripting Edition (VBScript) and Microsoft Windows Script Host to perform directory maintenance tasks.

    CDO:

    Collaboration Data Objects (CDO) was originally called "OLE Messaging" and later "Active Messaging". CDO is a COM wrapper of the MAPI library and can be called from any development language that supports automation. For example, Simple MAPI, CDO is primarily designed for client activities. CDO implements most but not all MAPI functionality, although far more than Simple MAPI.

    Some activities that can be accomplished using CDO:

    • Log onto the messaging system with specific profiles or with anonymous authentication.

    • Compose messages, address and resolve recipients, send, receive, and read messages, add attachments, automate replies.

    • Manage calendars; create meetings and appointments.

    • Manage folders and messages within the information store.

    • Manage Addresses, especially within the Personal Address Book (PAB).

    EXOLEDB:

    This is a high performance OLE DB driver. The ExOLEDB provider is a server-side component, and is therefore used only to access public stores and mailbox stores that reside on the same server. You can, however, access data on the server remotely by wrapping functionality into Component Object Model (COM) components, which can be utilized by ASP and other Web applications. The ExOLEDB provider is also ideal for use in COM+ components and Exchange store event and workflow sinks that run on the server. To access remote public stores and mailbox stores, use the WebDAV protocol, MAPI, or CDO 1.2.1.

    LDAP:

    The Lightweight Directory Access Protocol (LDAP) protocol is a distributed, hierarchical directory service protocol that you use to gain access to repositories of users and other network objects. Because LDAP is not typically tightly integrated with the host operating system, information can be kept in both LDAP and in a name service such as Network Information Service. When you use LDAP to gain access to the groups, you reduce redundancy and maximize LDAP's scalability.

    LDAP gives you the option of using paged or non-paged results when performing a search. With non-paged results, the maximum number of objects returned is limited by the MaxPageSize constraint on the domain server. With paged results, there is no maximum. You can return all the results. You set the LDAP client page size in the Search Options dialog box. This value cannot exceed the MaxPageSize constraint imposed by the domain server.

    MAPI:

    MAPI will generally mean MAPI32.dll, or the APIs contained. It's an API, implemented largely in MAPI32.dll (Messaging Application Programming Interface, 32 bit build). By using this, developers implement a series of Providers. Providers come in three major types, Transport Providers, Message Store Providers, and Address Book Providers. Providers are DLLs that implement a specific pseudo COM API, such as IMessageStore, and the underlying required interfaces, such as IMAPIProp.

    Schema:

    The Exchange store provides a means to define schema information for items. By using the schema capabilities of the Exchange store, you can make schema information about your application discoverable to schema-aware applications such as the Exchange store Structured Query Language (SQL) query processor.

    Search:

    You can search for items in the Exchange store using a familiar Structured Query Language (SQL) syntax, which is based on the syntax defined by the Microsoft Indexing Service Query Processor.

    Store Events:

    You can respond to events that occur in the Exchange store programmatically. With events, you can write your own custom logic that executes on the server in response to changes in the data in the Exchange store. Exchange store events occur:

    • When Exchange store items are saved, deleted, moved, copied, or modified.
    • When a store is started or shut down.
    • When a specific time interval has elapsed.
    • You can write event sinks that can receive notification of these events.

    WebDAV:

    The World Wide Web Distributed Authoring and Versioning (WebDAV) protocol provides access to an extensible set of associated properties. WebDAV also defines protocol commands used to search, move, copy, delete, lock and unlock resources, and make new collections of resources (folders).

    Webforms:

    Exchange Web forms is a Web-based forms technology that is built on Internet standards. An Exchange Web form is a Web page that is registered in the form registry of the Exchange store.

    WMI Providers:

    Microsoft Windows Management Instrumentation (WMI) supports custom Exchange management and monitoring applications through a set of WMI providers.

    Rules series # 2 : One or more rules could not be uploaded to Exchange server and have been deactivated. This could be because some of the parameters are not supported or there is insufficient space to store all your rules.

    • 1 Comments

    Couple of customers reported that after upgrading to Microsoft Office Outlook 2007 or  Microsoft Office Outlook 2003, they found that some of the rules are disabled and cannot be enabled. Remaining other rules work correctly. Also if you try to enable the disabled rules they receive the following error message:

    One or more rules could not be uploaded to Exchange server and have been deactivated. This could be because some of the parameters are not supported or there is insufficient space to store all your rules.

    Why it occurs: This behavior occurs if the rules that are in your mailbox exceed a size of 32 kilobytes (KB). The rules size limit for mailboxes on Microsoft Exchange Server is 32 KB. In Outlook 2003/Outlook 2007, the size of rules has increased mostly to provide support for the Unicode format.

    Note The rules size limit for mailboxes in Microsoft Exchange Server 2007 has been increased to a default size of 64 KB per mailbox. The rule limit is now a customizable limit up to 256 KB per mailbox.

    Please find the following KB, which helps us how to mitigate this situation and has couple of workarounds for this issue.
