mapi32.dll is an invalid Extended MAPI Library
Mail is not installed on your system
The above two messages are produced when I run mail merge in word 2003 on a Win2k3 Terminal Server with Exchange installed and I am selecting recipients from an existing list.
Also I get "Unable to obtain list of tables from the data source." if I choose Outlook address book as the recipient list.
This appears to be because the Exchange 2003 version of mapi32.dll located in c:\windows\system32\ has overwritten the Office 2003 version of MAPI32.dll and they are different.
To fix this problem I just took a copy of mapi32.dll from another Office 2003 installation and placed it in C:\Program Files\Microsoft Office\OFFICE11\ because it seems office will look there first, and voila it now works.
