outlook error

Hi @Tracy Collins

It is incredibly frustrating when you keep getting the "We're sorry, but Outlook has run into an error" message, especially when clicking the "Repair Now" or "Help" prompts doesn't actually fix the loop. I completely understand how disruptive it is to be locked out of your email like this.

The standard "Repair Now" button inside that error box acts as a "Quick Repair," which often isn't thorough enough to fix the underlying issue. Before we dive into more complex diagnostics, let's try a full Online Repair to completely refresh your Office installation files:

1. Close all Office applications (Word, Excel, Outlook, etc.).
2. Click the Windows Start button and open the Control Panel.
3. Go to Programs > Programs and Features.
4. Find Microsoft Office or Microsoft 365 in the list, right-click it, and select Change.
5. Select Online Repair (not Quick Repair) and click Repair.
6. Once the process is fully complete, restart your computer and try opening Outlook again.

You can also find the official Microsoft visual guide for this process here: Outlook for Windows not responding, hangs, freezes, or stops working

However, could you please provide me with a few more details so we can narrow this down?

• Account Type: What type of email account are you using (e.g., Exchange, IMAP, POP)?
• Outlook Version: Which exact version of Office/Outlook is installed on your computer?
• Web Access: Are you currently able to access your emails normally through the Outlook Web App (OWA) in your browser?

Let me know how the Online Repair goes, and we will get this sorted out!

The error "We're sorry, but Outlook has run into an error that is preventing it from working correctly. Outlook will need to be closed as a result. Would you like us to repair now?" is typically caused by problems with the Office/Outlook installation or its data files.

Follow these steps in order:

1. Install the latest Office and Windows updates
   Outlook works best when fully updated. Install all available Windows and Office updates as described in Install Office updates. If the issue continues, go to the next step.
2. Repair Office from Control Panel
   Repairing Office can fix the recurring error even if the in-app repair prompt did not help.
   1. Close Outlook and all other Office apps.
   2. Open Control Panel → Programs and Features.
   3. Find Microsoft Office (Microsoft 365 Apps / Office 2016/2019/2021).
   4. Right-click it and choose Change, then choose Repair (or Online Repair if available and needed).
   5. Let the repair complete and then restart Outlook.
3. Repair Outlook data files (.pst / .ost)
   If the error is caused by a damaged data file, use the Inbox Repair Tool:
   1. Close Outlook.
   2. Follow the steps in Repair Outlook Data Files (.pst and .ost) to run SCANSPST.EXE on your data file(s).
   3. Start Outlook again and test.
4. Repair the Outlook profile (if Outlook can stay open long enough)
   1. In Outlook, select File → Account Settings → Account Settings.
   2. On the Email tab, select the account and choose Repair.
   3. Follow the wizard and then restart Outlook.
      If Outlook cannot stay open, skip this step and focus on Office repair and data file repair.
5. If still failing after all repairs
   If the error persists even after Office repair and data file repair, a full clean reinstall of Office (including manually deleting remaining Office folders and related registry keys, then reinstalling) has resolved similar persistent “run into an error” issues, as described in the Q&A context. This is more advanced and should be done carefully, especially when editing the registry.
