Exchange 2007 All of a sudden "Initialize MAPI instance Failed"

Postby noel.pulis » Mon Oct 16, 2017 11:34 pm

Hi,

We have a client having CloudBacko installed on a Microsoft SBS Server 2008 with Exchange 2007. This was working fine with no issue for these couple of weeks. All of a sudden the mail-level backup started failing.

When you try to open the job from the Backup Sets and click on Sources, you will get the "Initialize MAPI instance Failed"

Restarted server and re-installed MAPI, no success.

Please I need urgent help as backup of mail is not working.

Many thanks.

Hi Noel,

Regarding this MAPI error, Can I ask you to reinstall the latest MAPI CDO on your exchange server? (Please uninstall your current version, restart the exchange server, and run the installer downloaded from the link as follow:)
- Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1 March 2014 Update

After removal of MAPI CDO, restart and re-install the backup worked.

Many thanks.
