Why has Outlook encountered an error?

The Outlook has encountered an error that is preventing it from working properly can be triggered by many possible issues, but we will highlight the most important here:

  • Third-party add-ins – If you installed any add-ins lately, that might cause Outlook to encounter an error. Starting Outlook in Safe mode can clear out this issue.
  • Firewall and antivirus interference – The firewall can block the connection with the server, preventing you from logging into your account and producing this error in Outlook or other Microsoft 365 software.
  • Software bugs – Like any other software, Outlook is prone to file corruption and bugs, but repairing Office will get this problem under control.

Now that we know what the possible problems might be, let’s fix Outlook using the solutions below.

Before getting into more complex tweaking, let’s perform the following:

  • Check your internet connection to see if it’s functioning properly, and restart your router.

  • Restart your computer and try to run Outlook again. Sometimes, this simple action may work.
  • Make sure you have installed all pending Windows updates on your computer.

  2. Type outlook /safe and click OK or press Enter.
  3. Choose the profile you want to use from the drop-down menu and hit the OK button.
  4. If Outlook can start in Safe mode that means some add-in is causing this problem and you should disable them one by one until you find which one is the culprit.

3. Perform a Clean boot

  1. Press the Win + R key combination, type msconfig, and press Enter or click OK.
  2. Go to the Services tab, check the box with Hide all Microsoft services at the bottom-left side of the page, and click on Disable all.

  5. Close Task Manager, click OK in the System Configuration window, and restart your PC for the changes to take effect.
