We can perform GetItem Exchange Web Service call to get Extended MAPI Properties refer my previous post How to get Extended MAPI Properties in the GetItem Exchange Web Service call? and can also perform FindItem based on the Extended MAPI Properties. In the sample code given below we would use CleanGlobalObjectId to perform FindItem for Calendar Items: NOTE: Following programming examples is for illustration only, without warranty either expressed or implied, including, but not limited to, the implied

Want to make working with Exchange Web Services (EWS) much easier to work with? There is a new API and new tool which can help. No matter which way you are doing or going to be doing EWS calls, you should be familiar with both the Exchange Web Services Managed API and EWSEditor. Exchange Web Services Managed API: The Exchange Web Services Managed API makes life much easier since it wraps a lot of calling code and logic which is needed to successfully execute EWS calls. No matter how you are doing

Matt’s very excited about the release of EWSEditor . This tool does for EWS what MFCMAPI does for MAPI. With this tool, Matt does what I did with MFCMAPI and what I recommend to anyone trying to learn a new API: the best way to learn an API is to write tools that use it. As you work with EWSEditor, you may notice a few things which are similar to MFCMAPI. This is no coincidence. EWS and MAPI, both designed primarily to interact with an Exchange server, share much of the same object hierarchy, which

I’ve seen a few cases come through where customer’s are trying to implement the customization features that were introduced with Exchange Server 2007 SP1.  There’s a few key areas that seem to cause trouble so I figured it would be worth walking through a simple scenario that covered many of the different aspects. ( Link to Part 1 of the series , Link to Part 2 of the series ) It’s been a long time coming, but I’m finally getting around to completing this series of posts.  I had originally

Want to learn more about Microsoft Exchange Server 2007 then Support WebCasts  are way to go. Support Webcasts are a free Internet broadcast service that is provided by Microsoft. You can view webcasts on-demand, and you can also download them in Microsoft Windows Media format for offline viewing. Here are few worthy of note webcasts which I found for the Exchange developers: Join us for a look at the various underlying components of Exchange Server 2007 Client Access Services. We cover the

While working with one of my customer we noticed that the yearly recurring appointment doesn’t show in Outlook Web Access or Exchange Web Services(EWS) application. Customer created a monthly or yearly recurring appointment. He set the request to occur on the second, third, or fourth weekday of a month. But, whenever we use Outlook Web Access (OWA) client or customer’s Exchange Web Service (EWS) application to view this request, the request is set to occur on the first weekday of the month; but strangely,

If you are using Exchange Web Services (EWS) against Exchange 2007 SP1, you may run into an issue where you are getting the ErrorNoPublicFolderServerAvailable and the error message says it’s not a proper error code. This error appears if you have set the ”Exchange2007_SP1”, your code is accessing public folder and there is no public folder on the Exchange server. Here is an example of what you might get back when using auto-generated proxies: Exception Type - System.InvalidOperationException Exception

One of my customer updated that whenever they try to make the remote Exchange Web Service (EWS) call from his C#.Net 2008 application (VS.Net 2008 - .Net Framework 3.x), he gets the following error: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel I had a detailed look at their application code. // Create the Exchange Service Binding ExchangeServiceBinding esb = new ExchangeServiceBinding();   // Add its relevant Credentials like user

In this we will see how to create & send e-mail messages using Exchange Web Service (EWS). It’s pretty simple with EWS to do. // Create the Exchange Service Binding ExchangeServiceBinding esb = new ExchangeServiceBinding(); // Add its relevant Credentials like user name, password, domain and URL esb.Credentials = new NetworkCredential(userName, Password, domain); esb.Url = @"https://myexchangeserver/EWS/Exchange.asmx" ; // CreateItemType and set its relevant properties/values CreateItemType request

One of the common request from our customers is to provide interface to work programmatically with Delegate Settings for Outlook. Microsoft Exchange Server 2007 Service Pack 1 (SP1) introduces delegate access and delegate access management through Exchange Web Services . The following delegate access functionality is available starting with Exchange 2007 SP1: Delegates can access the mailbox of a principal and perform search, create, delete, update, and copy operations. You can enable delegate access
