When Outlook gets stuck on “Loading Profile”, it usually means the Outlook data file (OST) is damaged, too large, or Outlook can’t connect to the mailbox properly. This issue is common after system crashes, sudden shutdowns, or network problems.
Here are a few simple fixes:
Restart Outlook in Safe Mode
Press Win + R, type outlook.exe /safe, and hit Enter.
If Outlook opens, an add-in is causing the issue.
Disable Add-ins
Go to File → Options → Add-ins and disable the unnecessary ones.
Create a New Profile
Open Control Panel → Mail → Show Profiles, create a new profile, and set it as default.
Repair the OST File
If the OST file is corrupted, Outlook may not load at all.
In such cases, using a reliable tool like Advik OST to PST Converter helps you extract all mailbox data from the damaged OST and save it into a PST file. You can then import the PST into Outlook and continue working without facing the loading issue again.
In short: Outlook gets stuck due to a problem with the profile or the OST file, and converting the corrupted OST into PST with a safe tool can help you recover everything smoothly.
