_Repairing_ the OST file with the tools from the Microsoft website didn't help. This was the only thing that helped: * kill outlook * restart outlook in _safe_ mode (this succeeds immediately) * close outlook * restart outlook (which now also succeeds immediately) A few PowerShell commands to do this: ```bash # Kill outlook (or click the 'x' in the right/top corner of the splash screen) (Get-Process outlook).Kill() # Find the location of outlook.exe $reg = 'HKLM:\SOFTWARE\Classes\Outlook.Application\CLSID' $outlook_clsid = (Get-ItemProperty $reg).'(default)' $reg = "HKLM:\SOFTWARE\Classes\CLSID\$outlook_clsid\LocalServer32" $outlook_exe = (Get-ItemProperty $reg).'(default)' # Start outlook in safe mode . $outlook_exe /safe
