How to Fix Outlook Closing When Repair Is Selected
Question details
The user needs to resolve an issue where Microsoft Outlook triggers an automated repair prompt upon startup, but entirely closes or crashes as soon as the user selects the Repair or Close options.

- Product
- Microsoft Outlook
- Device & OS
- Windows
- Scenario
- Attempting to launch the Microsoft Outlook application to access emails and bypassing or executing the startup repair prompt.
- Observed behavior
- Outlook displays a repair prompt when opened, but immediately crashes and closes the application completely when the user clicks either 'Repair' or 'Close', preventing any access to the software.
Ensure you are logged into your Windows computer with an administrator account, as you will need administrative privileges to modify or run an Online Repair for Microsoft Office applications.
Start Outlook in Safe Mode and Disable Add-ins
Running Outlook in Safe Mode bypasses all active add-ins, helping you determine if a conflicting third-party extension is causing the application to crash.
Often, outdated or incompatible COM add-ins interfere with Outlook's startup process, triggering the repair loop. Safe mode isolates the core application from these extensions.
Right-click the Windows Start button on your taskbar and select 'Run' from the power user menu.
Type 'Outlook.exe /safe' into the Run dialog box and click 'OK'. Choose your default profile if prompted.
If Outlook opens successfully, click on 'File' in the top-left corner, select 'Options', and then click on 'Add-ins' in the left sidebar.
At the bottom of the window, ensure 'Manage' is set to 'COM Add-ins' and click 'Go'. Uncheck all the boxes in the list to disable them, click 'OK', and then restart Outlook normally.

Perform an Online Repair of Microsoft Office
If Safe Mode does not resolve the issue, repairing the entire Office installation can fix corrupted system files that are causing the repair loop.

Frequently Asked Questions
Why does Outlook continuously prompt me to repair my profile?
This repair loop is usually triggered by corrupted data files (PST/OST), conflicting third-party add-ins, or damage to the core Microsoft Office installation files. When the internal diagnostic tool detects an anomaly upon startup, it forces the repair prompt.
Will running an Online Repair delete my Outlook emails and contacts?
No, running an Online Repair only fixes the Microsoft Office program files. Your emails, contacts, and calendar events are safely stored separately in your Outlook data files or synced directly with your cloud email server.
How do I create a new Outlook profile if the app refuses to open?
You can create a new profile without opening Outlook by using the Windows Control Panel. Search for 'Control Panel' in the Start menu, change the view to Large Icons, click on 'Mail (Microsoft Outlook)', select 'Show Profiles', and then click 'Add' to configure a fresh profile.
