If a user opens other's mailbox using Menu bar ( MDB->Open other mailboxes->From GAL... ), then MFCMAPI crashes. There should be an error dialog box. One window also appears, which shouldn't be present.

You don't mention the version of Outlook, but I believe this is a known issue with emsmdb32.

However - your report is contradictory - how can MFCMAPI crash and then somehow also display a window?

Outlook 2007 32 bit.

Ok - try applying the last updates for Outlook 2007. If you still repro, let me know if you can repro with 2013.

I got 2 different results, both of which were unexpected:

1) Using Outlook 2007 32 bitImage

2) Using Outlook 2013 32 bitImage

In both the cases, 'ranjan1' is opening other user's mailbox.

So it works in 2013. This was a bug in Outlook, not MFCMAPI.

In both the cases, the result is not proper. In case of Outlook 2013, I have opened mailbox of 'ranjan4' using 'ranjan1'. See the results.

You opened the mailbox that matched the DN you used.

If you really think something's wrong here with how Exchange is managing mailbox access, I highly recommend you open a support case:
