To verify the version of the Exchange Management Consoles (only applicable when backing up Exchange 2007):
Confirm if MAPI is functioning properly:
- If all the privileges have been given to the BE user and if still the backup fails with the same error:
- Create a new user and add it to the Administrators, Domain Admins, Backup Operators and Exchange Organization roles.
- The new user should have an activated mailbox.
- Make the new user the System Logon a/c and the BESA.
- Re-try the backup.
- Uninstall the Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1 from the Exchange 2007 Servers.
- Download the Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1 from the following link, and install it on the Exchange 2007 servers.
- Perform a search for ese.dll on both the Exchange Server and the Backup Exec Media Server.
- Ensure that the file version for ese.dll matches exactly. If it does not, review Add/Remove Programs (Programs and Features in Windows Server 2008) with the option to view installed updates and ensure the Service Pack level and Rollup level are the same.
- Verify the Exchange Agent component has been updated correctly, in Backup Exec Console, click Help | About Symantec Backup Exec for Windows Servers | License Information and ensure that "Agent for Microsoft Exchange Server" lists "Yes" under the "Installed" column.
- If not, re-run through the installation and check the option for "Agent for Microsoft Exchange Server".
- Otherwise remove the "Agent for Microsoft Exchange Server" license key and reinstall the key. And Restart Backup services.
- To fix the MAPI/CDO package mismatches when backing up Exchange 2007 in a clustered environment, review Add/Remove programs on both the Exchange physical nodes for "Messaging API and Collaboration Data Objects 1.2.1.
- The "Support Information" (Windows Server 2003) or "Version" column (Windows Server 2008) will reveal the actual file version information (e.g. 6.5.8069.0).
- If versions on both the Exchange servers do not match exactly, then correct this issue by uninstalling both MAPI/CDO packages and downloading and installing it again on both the physical nodes.
- The link to download MAPI/CDO:
- Edit the selection list for the Exchange backup job.
- Deselect the Microsoft Exchange Server Information Store (this will deselect all the storage groups).
- Reselect the Microsoft Exchange Server Information Store.
- Save the selection list.
- Run the job again.
- Use the Microsoft MFCMAPI Tool to test MAPI
When using Windows 2003 as the host for the Exchange server, Paged Pool Memory can limit the size of the snapshot which is necessary to allow the backup to complete. Microsoft has released documentation on how to resolve the limitation on the memory for sizable backups like Microsoft Exchange databases. The following link from Microsoft provides steps on making changes on the Exchange server. The same changes should be made on the Backup Exec server if it is also a Windows 2003 server and you are using the GRT (Granular Restore Technology) to allow individual email restores.
- If this issue is experienced for an Exchange 2003 environment and another Exchange 2003 server exists that is not showing the MAPI error :
- Locate the MAPI32.dll file in C:\Windows\System32 on the Exchange 2003 Server experiencing the issue and rename to MAPI32.old
- Locate the MAPI32.dll file on the working Exchange 2003 Server
- Copy the MAPI32.dll file from the working Exchange 2003 Server to the Exchange 2003 Server experiencing the issue into C:\Windows\System32
- Reboot the Exchange Server
- Re-attempt an Exchange 2003 GRT Backup to Tape
- If the MAPI troubleshooting steps do not resolve then Microsoft Support should be contacted to resolve MAPI connectivity issues.
