Answer 1

Hello,

Many users seem to have this issue recently. Microsoft is actually aware of it, but still investigating this issue. The current workaround is published here: https://support.microsoft.com/office/users-get-errors-0x800ccc0e-0x800ccc0f-synchronizing-gmail-and-yahoo-accounts-in-classic-outlook-e5a7b684-7c5c-4848-ab2d-d48291451f67

Answer 2

Follow these steps to get Gmail working again in classic Outlook and know when to contact support.

1. Confirm IMAP is enabled in Gmail
   1. In a browser, go to Gmail and sign in.
   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. Fix Outlook’s connection to Gmail (Microsoft apps & services access) If Outlook previously connected but now fails with IMAP/auth errors, reset the Microsoft access grant:
   1. Close Outlook.
   2. In a browser, sign in to your Google account on Google.com.
   3. Select your profile picture > Manage your Google Account.
   4. In the left menu, select Security.
   5. Scroll to Your connections to third-party apps & services and select Microsoft apps & services.
   6. Under Access you've given to Microsoft apps & services, select Remove all access and confirm.
3. Clear old Google IMAP credentials from Windows
   1. Open Credential Manager from the Windows 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 hover over the name until the full name shows tp_google_imap_oauth2.
   5. Select Remove for each Gmail-related MicrosoftOffice16_Data:OAUTH2 entry (there are typically two per Gmail account).
4. Re-add the Gmail account in classic Outlook
   1. Start Outlook.
   2. Add the Gmail account again.
   3. When the Google sign-in window opens in the browser, sign in and, on the permissions screen, ensure the option allowing Microsoft apps & services to “Read, compose, send, and permanently delete all your email from Gmail” is checked.
   4. Complete the sign-in.
5. If Outlook shows “browser or app may not be secure” or similar Ensure Outlook is updated to a build that includes the Gmail sign-in fix:
   1. In Outlook, go to File > Office Account > Update Options > Update Now.
   2. The fix is available starting with Current Channel Version 2404 (Build 17531.10000) and later, and other listed channels.
   3. After updating, retry adding the Gmail account.
6. When to contact Microsoft support Contact Microsoft support if, after completing all steps above, Outlook still cannot add the Gmail account or continues to show IMAP/authorization errors. Provide:
   • Exact Outlook version/build.
   • Exact error text when adding the account.
   • Confirmation that IMAP is enabled in Gmail and that Microsoft apps & services access was removed and re-granted.
