December 2011 Release of MFCMAPI and MrMAPI

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…

Enabling Kerberos Authentication

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 through the UI: PR_PROFILE_AUTH_PACKAGE in the global profile section…


November 2011 Release of MFCMAPI and MrMAPI

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 of jump that’s normally only accompanied by a full UI…


MAPICDO 6.5.8244

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 must uninstall it…


Random MAPI_E_CALL_FAILED Errors With Exchange 2010

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 calls fail, except that all of…


The Elusive 0x81002746 Error

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…


September 2011 Release of MFCMAPI and MrMAPI

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 you want to know what…


Undocumented MAPI

It has come to our attention that a handful of functions exposed in the MAPI Stub Library don’t have documentation in the Outlook 2010 MAPI Reference. We’re working on correcting that, but in the meantime, here are the functions and some basic documentation of what they do. Update: All of these now have articles in…


July 2011 Release of MFCMAPI and MrMAPI

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 of the features I’ve added to MrMAPI to…
