This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
Starting today, outlook will not open from my desktop. I get messages that "Outlook stopped working" and it hangs "Loading Profile". I've used Outlook for decades and can't imagine what suddenly changes. Help!
I did successfully open it in safe mode (from the command line), but no luck with the normal process.

Hello,
The reason for the issue can be your pst size became heavy as you are using the outlook for many years. It can be due to a add on issue also. Sometimes, an automatic update can also break it.
Try opening it in safe mode, which disables add-ins.
Another aspect is your disk issues where the pst file saves (usually C:\ drive) can have an impact. So do a disk check, defragment etc. also
Most importantly, when the outlook is back again, set an archive rule to move all the files before xx months to a separate folder. Or delete old files
Please mark as "Accept the answer" if the answer helps you. Your suggestion will help others also !

Since it can be successfully opened in safe mode, there might be some add-ins in your Outlook client that cause this issue. Please try disabling your add-ins one by one until you find the one which caused your issue and disable it to resolve your problem. Or you can disable all the add-ins to see if it works(File > Options > Add-ins > Manage > uncheck the add-ins in the list to disable. For example, like below)
Besides, custom navigation pane settings in Outlook may also cause issues like this. Please try running the /resetnavpane command to remove all customizations to the navigation pane (Press Win + R, type “Outlook.exe /resetnavpane”, press Enter).
Follow up these Official guidance and repair your Outlook installtion.

Same issue i had last day. I re-installed my Outlook and it was done.
Sounds like a hardcore method, but it was the one and only solution that helped me.
