Hello,
After upgrading from v10 to v11, I’m also getting an error message stating that Microsoft Outlook (Classic) is not running as the default email program.
This message appears alongside the eM Client logo on the taskbar.
My backup programs for Outlook PST files also trigger this error message and then stop working.
I’ve tried various solutions I found online, but haven’t found a fix. I’ve now uninstalled eM Client v11 for the time being, but I can’t revert to v10 because v11 somehow updated the database.
Windows 11, eM Client 11.0.1054.0, Outlook 2024, PSTBackup
Best regards
