FixMAPI

Clearly, keeping up on this blog hasn't been at the top of my to-do list. We've made some big changes at Artech, and business is booming at the moment, so I've been busier than ever.

This blog was originally going to be a collection of articles that I could spit out at my own pace, and then use in a newsletter format on a periodic basis to send to our clients. However most of my clients wouldn't really care to read any of this, so it's basically turned into a collection of fixes for which I couldn't find anything on Google when trying to fix an error myself.

A recent example of this came up when I migrated a client from GroupWise 6.5 to Exchange 2007 with Outlook 2007 on the client side. The vast majority of people could no longer use any mailto links or the "Send to" function of Explorer when choosing Mail Recipient. The only solutions people tended to talk about was to verify that you had Outlook selected as the default email program under Internet Explorer.

So if you are being prompted to "Choose Profile", and then nothing happens when trying to use any of these functions, check out the version of your mapi32.dll. There's a program that's been pushed out since IE5 called fixmapi.exe in your system32 directory, which makes a backup of the current MAPI DLL, and restores the correct version. Be careful, because this will break older versions of Outlook.

Hopefully this will help other people when looking for a solution to this issue.
