One of my gmail accounts quit working on all my desktop computers.

Question

I don't understand what went wrong, I still get my email on my phone but no longer on my windows 11 computers. It just started yesterday. One of my Gmail accounts is working as it should on the same computer. It has worked for years and yesterday it quit working.

Answer 1

Hello,

If your Gmail works on your phone, the account is active. In Classic Outlook for Windows, go to File, Account Settings, Account Settings, select the affected Gmail account, then click Repair. If repair fails, remove the account and add it again using Add Account so Outlook completes the secure Google sign in required by Microsoft. Also confirm IMAP is enabled in your Gmail web settings under Forwarding and POP IMAP.

Answer 2

The most likely cause is a recent change affecting how classic Outlook connects to Gmail for one of the accounts, while the phone app continues to work because it uses a different connection method.

Use these steps that match classic Outlook on Windows:

1. Confirm IMAP is enabled for the problem Gmail account
   1. In a browser, sign in to the Gmail account that stopped working.
   2. Select the gear icon > Settings.
   3. Go to Forwarding and POP/IMAP.
   4. Under IMAP access, make sure Enable IMAP is selected.
   5. Select Save Changes.
2. Remove old Microsoft access for that Gmail account
   1. Close Outlook on all desktop computers.
   2. In a browser, sign in to the same Gmail account.
   3. Select the profile picture > Manage your Google Account.
   4. Select Security.
   5. Under Your connections to third-party apps & services, select Microsoft apps & services.
   6. Under Access you've given to Microsoft apps & services, select Remove all access and confirm.
3. Clear the stored Gmail OAuth credentials in Windows
   1. Open Credential Manager from the Start menu (on some systems via Control Panel > Credential Manager).
   2. Select Windows Credentials.
   3. Under Generic Credentials, find entries starting with MicrosoftOffice16_Data:OAUTH2.
   4. Expand each and look for those that include tp_google_imap_oauth2 in the full name. These correspond to Gmail accounts.
   5. Remove the entries for the affected Gmail account (there are typically two per Gmail account).
4. Reconnect the Gmail account in Outlook
   1. Start Outlook.
   2. If the account is still in the profile but not syncing, use the Sign in via browser prompt if it appears, and when the Google sign-in page opens, sign in and be sure to allow Microsoft apps & services access.
   3. If the account was removed, go to File > Add Account, enter the Gmail address, and complete the browser-based sign-in and consent.

If Outlook still does not sync messages or folders after this, verify that the account type for the Gmail address is set up as IMAP (not POP or another type) and re-add it using the automatic setup from Control Panel > Mail > Email Accounts > New.
