So Long System Attendant Mailbox

Dave has a post up about the fate of the System Attendant Mailbox in Exchange 2010 . Since this mailbox isn’t there anymore in 2010, if you have a solution that depended on it, you’ll need to rework it. Dave gives a few suggestions, such as creating your

My colleague Edwin, writing for the Exchange Support Team Central Europe blog , posted an article on accepting meeting requests with CDO . The key takeaway from the post is this: This means that when calling the respond method on meeting updates / requests,

More Fun With Check Name

I just closed case where the customer was trying to create a profile but Check Name was constantly prompting for credentials and then failing. This wasn’t the reconfig issue I mentioned before – they couldn’t create the profile in the first place. Even

Auth and Check Names

When I posted the Referral Madness article, there was an intriguing comment that I didn’t get a chance to investigate until it came up in a case. The commenter noted that when we used RPC_C_AUTHN_GSS_NEGOTIATE as our authentication mechanism, we could

Your Cache is No Good Here

The first time we saw this, we wrote it off as an odd thing one customer did. But we’ve seen it a few times over the past couple years and it deserves some discussion. The issue is with Exchange Client Extensions (remember – they’re dead in 2010 !): Customers

Mapi32.lib and 64 Bit MAPI Programs

I’m in the process of updating the Outlook 2007 MAPI Samples for Outlook 2010 and ran into something that deserves some clarification. Suppose you have a 32 bit application which uses MAPI and which links in mapi32.lib. In preparation for 64 bit MAPI,

Installing the MAPI Headers

I noticed something about downloading/installing the Outlook 2010 MAPI headers . I use Windows Server 2008 as my development machine, and when I ran the installer, which is really a self extracting zip file, it offered to copy the headers to “C:\Program

CDO: Always a Bridesmaid

Suppose you’ve scheduled an meeting and sent out meeting requests to a number of recipients. Some of those recipients don’t like the time you’ve scheduled for the meeting and decide to propose a new time . At this point, you will receive a message with

MFCMAPI and Old Versions of Visual Studio

Ever since I went to the new Vista style icon for MFCMAPI, it’s not been possible to compile in Visual Studio 6 . I’ve spent some time looking at this, and it appears the only clean way to get VS 6 working again is to remove compression from the icon,

Exchange MAPI and the Form Manager

Had a customer contact me recently asking why MAPIOpenFormMgr doesn’t work with the Exchange MAPI download . Actually, it wasn’t working in Exchange 2003 either. I’m not sure exactly when it last worked in Exchange’s implementation of MAPI. We might have

But I Really Need To Open 500 PSTs!

Today we’re revisiting an issue I first encountered in Outlook 2003. We had a customer, a law firm, who kept all the mail associated with a particular case in a PST. Their users would pass these PSTs around, and depending on their case load, a single

Accepting Appointments With CDO May Break Embedded Message Attachments

This is an issue that has only been reproduced so far with Exchange 2003 , but I wanted to document it here in case anyone else is running in to it. Suppose you have a CDO 1.21 based application which uses GetAssociatedAppointment to accept meeting requests.

The Fifth MAPI Multithreading Rule

We had an issue recently where DDE broadcasts were being blocked on a system. The customer noticed that the problem happened after they called MAPIInitialize on their worker thread. Our investigation gives us a chance to add a 5th rule to the MAPI Multithreading
