How to fix the “Something went wrong” error in Outlook for Windows.

1. Edit Registry Files Autodiscover is a nifty feature that allows Outlook to automatically configure email account settings without requiring manual input from the user. If this service receives any unexpected results from the third-party web server, Outlook might display the "Something went wrong" error message. To resolve this, you will need to make a few changes to the registry files on your PC. As you may be aware, making incorrect changes to the registry files can render your system inoperable. Hence, it is advisable to back up all of your registry files or create a restore point before proceeding. Press Win + R to open the Run dialog box. Type regedit in the box and press Enter. Select Yes when the User Account Control (UAC) prompt appears. Paste the following path in the address bar at the top and press Enter to quickly navigate to the AutoDiscover key. Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\XX.0\Outlook\AutoDiscover Replace XX.0 in the above path with your version of Office (16.0 = Office 365, Office 2019, and Office 2016, 15.0 = Office 2013). Right-click on the AutoDiscover key and select New > DWORD (32-bit) Value. Create DWORD in Registry Rename the DWORD to ExcludeHttpsRootDomain. Double-click the newly created DWORD and set its value to 1. Right-click on the AutoDiscover key again and select New > DWORD (32-bit) Value. Name the DWORD ExcludeHttpsAutoDiscoverDomain. Double-click the ExcludeHttpsAutoDiscoverDomain DWORD and set its value to 1. Create two more DWORD values named ExcludeSrvRecord and ExcludeLastKnownGoodUrl and set their values to 1. AutoDiscover in Registry Editor Restart your PC after this and check if you still get the “Something went wrong” error in Microsoft Outlook. 2. Open Outlook in Safe Mode At times, third-party add-ins in Outlook can disrupt app processes and trigger such errors. To verify if this is the case, you can try starting Outlook in safe mode.
