What should I do if Outlook stuck on loading profile?
There are several steps you can take to resolve the issue if Outlook stuck on loading profile. First, try restarting Outlook in safe mode by holding down the CTRL key while opening the application. If this doesn't work, try repairing your Office installation using the Control Panel. If the issue persists, create a new Outlook profile by opening the Mail applet in the Control Panel and clicking "Show Profiles." If none of these steps work, try reinstalling Office.
If your Outlook stuck on loading profile, then run it with the administrative privileges. Also, make sure that you launch the MS Outlook in safe mode.Joseph Thomas (Email Technical Support)
