Duet is not supported on a computer that has Exchange System Manager (ESM) installed

  • Article

Duet uses Extended MAPI for some functionality and therefore requires that the computer be in a supported MAPI configuration. Having Exchange System Manager (ESM) installed on an Outlook client is not a supported configuration and generally results in MAPI call failures.

Microsoft does not support installing Exchange Server components and Outlook on the same computer

 

Symptoms

In the Microsoft.OBA.SystemTray.Duet.Log file located in the user's temp directory you may see the following entries added each time you launch the Duet Utility.

Solution

If you want to install Duet on a computer that currently has both Outlook and Exchange System Manager installed you will need to remove Exchange System Manager and get Outlook's MAPI files back onto the system.

Here are the steps to get the correct version of MAPI on the computer:

1. Remove ESM (In Add/Remove Programs choose Change on the top level Exchange component and Remove for the ESM tools.)

2. Remove Outlook (not all of Office, just Outlook)

3. In C:\Windows\System32 rename MAPI32.DLL to MAPI32.OLD and if MAPI32x.DLL exists rename it to MAPI32x.OLD (do not rename mapistub.dll)

4. Reinstall Outlook

5. Run C:\Windows\System32\fixmapi.exe   (which basically copies mapistub.dll to mapi32.dll)
