Hello, I'm Quinn and here to help!

Try these steps to fix the issue:

Try to Remove and recreate your Outlook profile, but first make sure you have a backup of your files

1. Press Win + R, type %LOCALAPPDATA%\Microsoft\Outlook, and press Enter
2. Look for .pst or .ost files
   • .OST files (Exchange/IMAP) can usually be recreated, no need to back them up
   • .PST files contain local emails and should be copied to a safe location
3. Copy these PST files to an external folder, USB drive, or cloud storage

Note: Removing a profile will not delete your email from the server, but any locally stored data not backed up will be lost. Make sure important files are saved elsewhere. To backup your files:

1. Make sure you have a backup of your locally stored data
2. Press Win + R, type control, and press Enter.
3. In Control Panel, search for Mail.
4. Open Mail (Microsoft Outlook).
5. Under Profiles, Click Show Profiles.
6. Select your current profile > Remove.
7. Click Add to create a new profile.
8. Add your Gmail account here.
9. Set the new profile as default.
