It;’s here! It’s finally here! The May 2013 update of MAPICDO is live here: http://www.microsoft.com/en-us/download/details.aspx?id=39045 At that same link, you’ll also find the long awaited configuration guidance. It’s not immediately obvious it’s there. Just hit the Download link and it will be offered...

Anybody remember that Message Header Analyzer App for Office I wrote about last month? Well, the folks who do support for Exchange and Office 365 caught wind of it and liked it. In fact, they liked it so much they asked me to port the code into their Remove Connectivity Analyzer. Here’s the blog entry...

So – I’ve been playing a lot with Apps for Office lately. I even wrote and published an app: http://office.microsoft.com/en-us/store/message-header-analyzer-WA104005406.aspx My management encouraged me to put together a presentation on everything I learned while developing this app. I did, and they asked...

As several of you have noted, we recently released an update for the MAPICDO package . This is the update you have all been waiting for, as it is now possible to build an RPC/HTTP enabled profile to connect to Exchange 2013. What several of you have also noticed is that this update did NOT come with...

http://msdn.microsoft.com/en-us/library/ee159108(v=exchg.80).aspx If you’ve got an application that processes e-mails paying attention to the PR_RECEIVED_BY_* and PR_RCVD_REPRESENTING_* properties, you may notice these properties showing up on e-mails in the Sent Items folders of your users. That is...

I’ve just been given permission to announce we’re targeting the release of the updated MAPICDO which will support Exchange 2013 to coincide with the release of Exchange 2010 SP3. Exchange 2010 SP3 was announced a while back on the Ehlo blog . As you can see from that announcement, SP3 provides much needed...

I’ve just been given clearance to publicize this since apparently it was discussed at MEC: The MAPICDO download *will* be updated to support Exchange Server 2013. This is important because: As has been discussed , Exchange Server 2013 will only allow MAPI connections over RPC/HTTP, aka Outlook Anywhere...

One of the lesser known tricks in MAPI is that when you open a distribution list ( MAPI_DISTLIST ) from an address book using OpenEntry , if you don’t specify an interface what you get is not an IMailUser , but is in fact an IDistList , which inherits from IMAPIContainer . This gives you a means to access...

We recently resolved a case here where a customer, as part of their larger application, was using SetReceiveFolder to direct messages of their message class to the correct folder so their application could do further processing on them. However, when they tested their application in cached mode, it didn...

We did it! MFCMAPI is now on Wikipedia ! The March 2012 Release (build 15.0.0.1032) is live: http://mfcmapi.codeplex.com . No UI changes this round, so no new screenshot. I did fix some interesting bugs and added a few nice features. Probably the nicest feature is new MAPI call logging. I‘ve...

Remember Jason’s article about the reconnect logic we added to Exchange’s MAPI ? The idea was that if your GC went down, Exchange’s MAPI should be able to reconnect to a different GC and proceed smoothly. Mostly smoothly though, since the last call sent to the old GC may fail with MAPI_E_END_OF_SESSION...

No one’s taking my subtle hints about Wikipedia . One more try: It sure would be nice if someone added MFCMAPI to the article about MAPI . The January 2012 Release (build 15.0.0.1031) is live: http://mfcmapi.codeplex.com . I’m continuing to crunch on the UI overhaul. This release has...

What’s an app got to do to get on Wikipedia ? You know I can’t put it there myself – that’s against the rules . The December 2011 Release (build 15.0.0.1030) is live: http://mfcmapi.codeplex.com . When I started working on the UI overhaul, I knew it was going to take a few releases to get it right. After...

Matt has just announced that EWSEditor has been updated and moved over to Codeplex. Read his announcement here , then go download EWSEditor here . Enjoy!

We had a customer recently who was using Outlook 2010’s MAPI in their application to talk to the Exchange server. They wanted to enable Kerberos authentication, but were having trouble enabling it programmatically. They had found the property that gets changed when you enable Kerberos authentication...

Still no mention of MFCMAPI on Wikipedia . I had such high hopes. Sigh. The November 2011 Release (build 15.0.0.1029) is live: http://mfcmapi.codeplex.com . Note that build number. That’s right. I jumped all the way from 6 (where I’ve been stuck forever) to 15. That’s the sort...

It’s been a while, but we just shipped a new version of the MAPICDO download . Per tradition, I’ve put together release notes: Installation details: This version is 6.5.8244.0. All of the files in the update are dated October 17th, 2011. If you already have a version of the MAPI Download installed, you...

We have gotten a number of cases lately involving applications using Outlook 2010's MAPI failing when connecting to Exchange 2010 servers. The primary symptom observed by our customers is that random MAPI calls to Exchange return MAPI_E_CALL_FAILED. At first blush, there is no rhyme or reason as to which...

If you look around for it, you’ll find a lot of posts on a 0x81002746 error that you might get from ConfigureMsgService . But no one seems to know what the error really means or why it happens. I thought I’d fill in some details. For starters, this error has nothing to do with WSAECONNRESET, which is...

Before we get to business, a comment: MFCMAPI does not appear anywhere in Wikipedia . This is a sad. Very very sad. The September 2011 Release (build 6.0.0.1028) is live: http://mfcmapi.codeplex.com . We got a handful of new features this time. MrMAPI can now parse flags on the fly, For instance, if...

The July 2011 Release (build 6.0.0.1027) is live: http://mfcmapi.codeplex.com . This round, the focus was on bulking up MrMAPI’s feature set. MrMAPI is one of the core data collection tools being used in a future update to our Software Diagnostics Platform for Outlook issues. This has driven several...

As I intimated before , Outlook’s MAPI supports a special kind of store entry ID which allows you to encode the full DN for the server and avoid redirects. Here’s the documentation for it. An Exchange Store Entry ID encodes an Exchange server and mailbox for us in OpenMsgStore . The base version of this...

Here’s the scenario the customer gave us: They use Outlook’s MAPI and a single MAPI profile connect to an admin mailbox, and then use CreateStoreEntryID and OpenMsgStore to open various work mailboxes to do their processing. All day they’re opening and closing these mailboxes. In some...

We recently encountered an issue where, in the customer’s code, a call to GetProps for a particular message failed with MAPI_E_CALL_FAILED. We found that MFCMAPI had trouble getting properties on the message as well. The curious thing was that if we made a GetProps call for one or two properties, it...

There’s a handle leak in MAPICDO . It’s been there just about forever and can easily be avoided. I just wanted to describe it here to help you recognize it so you can code around it. The basic setup to see the leak is this: A program has multiple child threads which are each logging in and out of MAPI...
