Hi Nancy Barker
Thanks for sharing the details, I understand this is frustrating, especially since it was working before.
I can see that @Gabe Bratton already shared the step about clicking the yellow bar in Outlook and signing in to Google to grant access. To avoid repeating that, could you please confirm first:
- Have you already clicked the yellow “Sign in via browser" bar and completed the Google sign‑in?
- If yes, did you see an error, or did it complete successfully but mail still doesn’t sync?
If you already signed in but Gmail still won’t sync, please try this workaround:
- Close Outlook.
- In your Google account > Security > Your connections to third-party apps & services, open Microsoft apps & services and choose Remove all access.
- Open Credential Manager in Windows. Under Windows Credentials, remove the entries that start with MicrosoftOffice16_Data:OAUTH2 and include tp_google_imap_Oauth2. Microsoft identifies these as the stored Google IMAP credentials for the Gmail account.
- Open Outlook again and sign in to Gmail once more, making sure that the permission box for “Read, compose, send, and permanently delete all your email from Gmail” is selected.
Please feel free to let me know how it goes. Thank you for your time and understanding.
