Have you ever found yourself stuck at the Outlook load dialog, where all it says is “Processing” forever, no matter how long you wait?
Try the following, which should load Outlook without addins and get your OST open:
- Right-click the Start button, and click Run.
- Type Outlook.exe /safe
Assuming it opens, close Outlook again and let it close your Outlook data files properly by waiting. Then run Outlook again normally.
