Problem description:

Problem with location of Simple MAPI MAPIResolveName function can arise during Mobilchange installation on Windows 2003 + Exchange 2003 when using Outlook 2003 as e-mail client.

Until now this function was searched in MAPI32.dll library and then (if not found) in library referenced by HKLM\SOFTWARE\Clients\Mail\Microsoft Outlook\DLLPathEx registry value, see also KBMX20050509-155316RAS record.

Solution:

From Mobilchange 4.0.36 was setup changed in this way:
Registry value HKLM\SOFTWARE\Datasys\UMS\info\installed\LegacyMAPI is read. If LegacyMAPI = "yes" or "1", original algorithm described above is used.
If LegacyMAPI doesn't exist or is not "yes" nor "1", this method is used:

• read HKLM\SOFTWARE\Clients\Mail\Microsoft Outlook\DLLPath value and search function in this library
• if not found, read HKLM\SOFTWARE\Clients\Mail\Microsoft Outlook\DLLPathEx value and search function in this library
• if still not found, use MAPI32.dll

Further information:

If you want to use older method of finding MAPIResolveName, set registry value HKLM\SOFTWARE\Datasys\UMS\info\installed\LegacyMAPI = "yes" (with no quotations) BEFORE installation. If value doesn't exist, create it.
