Issue



When opening Outlook 2010 64-bit on a client machine that is being backed up using the Desktop Laptop Option (DLO) Agent an error message reports:

"Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client."


Error




Environment



Client Machines are composed of being 64-bit operating systems with Outlook 2010 64-bit installed


Cause



Due to Outlook 2010 64-bit not being supported as per: TECH136247 and incremental backups of PST files being enabled.


Solution



There currently is no way to resolve this issue due to the unsupported nature of Outlook 2010 64-bit. There is a way to remove the error message that is produced when opening Outlook by disabling Incremental backups of PST files that Outlook 2010 64-bit uses. Uncheck Incremental backups of PST files by performing the steps below:

1. On the Media Server, open the Backup Exec Console
2. On the navigation bar, click Job Setup
3. In the task pane, under Backup Strategy Tasks, click Configure desktop and laptop backups.
4. On the DLO navigation bar, click Setup.
5. In the Settings pane, click Profiles.
6. Right-Click on the profile that you wish to change and select Properties.
7. Select the Options tab.
8. Uncheck the checkbox Enable message level incremental backups of Outlook PST files
9. Apply your changes

Note: This removes the capability of incremental backups of the PST file for all users that use this profile. Some users that are used on non-Outlook 2010 64-bit Clients should have a different profile that has this feature enabled. Duplicated the profile and then deselecting incremental backups of PST files and then applying that profile to the users that exclusively use Outlook 2010 64-bit might be a solution for some.
