Solution: When you are using an MSI-based installation of Outlook 2016 or previous, you can configure Microsoft Update to also check for Office updates. When you use a Click-to-Run based installation of Outlook 2013, Outlook 2016, Outlook 2019, Outlook 2021 or Microsoft 365, then you can manually check for updates via the button that is show by going to File-> Office Account in Outlook. Fixes for known issues and bugs in Outlook are released on a monthly basis.

To start Outlook in Safe Mode you’ll need to start Outlook with the “safe” switch;

• Windows 7 Start-> type; outlook.exe /safe
• Windows 8 Start Screen-> type; outlook.exe /safe (just start typing, a search box will automatically become visible)
• Windows 10 Start-> type; outlook.exe /safe (just start typing, a search box will automatically become visible or type in the command in the Search box)
• Windows 11 Start-> type; outlook.exe /safe (just start typing, a search box will automatically become visible or type in the command in the Search box)
• All Windows versions Hold the CTRL button when clicking on the Outlook button to start it. You will get prompted whether you want to start Outlook in Safe Mode.

When typing, please note the space between outlook.exe and /safe. For alternative methods of starting Outlook in Safe Mode see this Quick Tip.

See the next 3 troubleshooting steps below for further analysis of the issue. If it doesn’t work in Safe Mode either, the next 3 steps will probably not help you either to solve it and you can continue with.

Cannot open the Outlook window

Solution: Start Outlook with the resetnavpane switch;

• Windows 7 Start-> type; outlook.exe /resetnavpane
• Windows 8 Start Screen-> type; outlook.exe /resetnavpane (just start typing, a search box will automatically become visible)
• Windows 10 Start-> type; outlook.exe /resetnavpane (just start typing, a search box will automatically become visible or type in the command in the Cortana Search box)

When typing, please note the space between outlook.exe and `outlook.exe /safe`1. If you encounter this issue more often, see this Quick Tip to find a more definitive solution.

Reset dat-files

Solution: Reset `outlook.exe /safe`3 and `outlook.exe /safe`4 by renaming them to `outlook.exe /safe`2 when Outlook is closed. You can find them in the locations below;

• extend.dat
  • This file keeps the settings of installed Exchange Client Extensions add-ins and their status.
  • `outlook.exe /safe`6
• outcmd.dat
  • This file contains your Toolbar customizations.
  • `outlook.exe /safe`7

Tip! If you are having trouble locating these folders you can also use OutlookTools (free!)

Disable add-ins

Often, but not always, this is accompanied by an error similar to:

“The add-in <reference to add-in> could not be installed or loaded. This problem may be resolved by using Detect and Repair on the Help menu. Unable to load <reference to add-in dll>.“

The instructions given in the error will seldom actually fix this issue as the issue is more likely to be caused by the add-in itself, rather then by an Outlook installation issue.

Solution: again and disable all your add-ins. After this, you can start Outlook normally again and see if it works now. If so, you can enable them one by one until Outlook fails to load again. The add-in you last enabled is most likely the cause of your issue. Uninstall or reinstall this add-in or check with the vendor for updates or contact them for further troubleshooting their add-in.

You can enable/disable Outlook add-ins in the following locations;

• Outlook 2007 Tools-> Trust Center…-> section Add-Ins
• Outlook 2010 / 2013 / 2016 / 2019 / 2021 / Microsoft 365 File-> Options-> section Add-Ins

For more detailed instruction on how to enable or disable add-ins see this Quick Tip. If you you get an error that you cannot disable the add-in see this Quick Tip instead.

Tip! Virus scanners which integrate themselves with Outlook are known to cause a lot of issues. Uninstalling this part of your virus scanner is strongly advised; you’d still be sufficiently protected by your on-access scanner part of the virus scanner. For more details see this Quick Tip.

Use scanpst.exe to fix Outlook Data File errors

Often this issue is accompanied by the message;

“Errors have been detected in the file <path to pst-file>. Quit all mail-enabled applications, and then use the Inbox Repair Tool.“

Solution: Use scanpst.exe to scan the mentioned pst-file for errors. The location of scanpst.exe depends on your version and language of Outlook.

• Microsoft 365 / Outlook 2021 / Outlook 2019 / Outlook 2016 Click to Run `outlook.exe /safe`8
• Outlook 2016 (MSI-based Volume License installation) 32-bit Windows: `outlook.exe /safe`9 64-bit Windows: `outlook.exe /safe`0 64-bit Outlook: `outlook.exe /safe`9
• Outlook 2013 32-bit Windows: `outlook.exe /safe`2 64-bit Windows: `outlook.exe /safe`3 64-bit Outlook: `outlook.exe /safe`2 Click to Run: `outlook.exe /safe`5
• Outlook 2010 32-bit Windows: `outlook.exe /safe`6 64-bit Windows: `outlook.exe /safe`7 64-bit Outlook: `outlook.exe /safe`6
• Outlook 2007 32-bit Windows: `outlook.exe /safe`9 64-bit Windows: `outlook.exe /safe`0

When the scan is done and errors have been fixed, run scanpst.exe again until no errors are found anymore. If after scanning the file more than 3 or 4 times errors are still found, you might want to copy over your data in a new pst-file.

Recreate your mail profile

Solution: Recreate you mail profile via the Mail applet in Control Panel. You can first add a new mail profile without deleting or otherwise affecting your current configuration just to see if it will indeed solve your issue. If so, you can easily migrate your Outlook data file from the broken mail profile to the newly created one. This process is described in detail in this guide.

Run a Repair, Office Diagnostics or reinstall Office/Outlook

Solution: By running a Repair, Office Diagnostics or by reinstalling Office/Outlook you can probably resolve this issue. Note that during this process no files or settings of Outlook or other applications will be removed but it will of course never hurt making a backup of your Outlook data before you continue.

Depending on your version of Office/Outlook and/or Windows, you’ll have several of the following options available to you to start one of the above processes;

• Control Panel-> Add/Remove Programs…
• Control Panel-> Uninstall a Program
• Windows 10: Start-> Settings-> Apps
• Windows 11: Start-> Settings-> Apps-> Installed apps
• Insert the Office CD/DVD-> run Setup.exe-> choose Repair or uninstall Office completely and then install it again.

Tip! After running any of the above processes, make sure you again to verify that all updates have been installed.

If the uninstall process fails, you can manually uninstall Office from your computer or use the Office Uninstall Support Tool (OffScrub.exe).
