Answer 3

The error synchronizing Gmail folders in classic Outlook is a known issue with Gmail accounts in classic Outlook and is typically caused by a problem with the Google/Outlook authorization for IMAP.

Use these steps, in order:

1. Confirm Outlook build and use the built‑in retry
   • In Outlook, go to File > Office Account > About Outlook and confirm that Current Channel Version is 2412 Build 18324.20168 or later.
   • When the sync error appears, select the Retry link in the error window.
   • In the browser sign‑in page that opens for Google, make sure to check the box:
     • “Read, compose, send, and permanently delete all your email from Gmail.” under Select what Microsoft apps & services can access.
   • Complete the sign‑in and let Outlook resync.
2. If Retry does not fix it, use the manual workaround Step 1 – Remove Microsoft apps & services access in Gmail
   1. Close Outlook.
   2. Sign in to the Gmail/Google account at google.com.
   3. Select the profile picture > Manage your Google Account.
   4. Select Security on the left.
   5. Scroll to Your connections to third-party apps & services and select Microsoft apps & services.
   6. Under Microsoft apps & services has some access to your Google Account, select See Details.
   7. Under Access you've given to Microsoft apps & services, select Remove all access.
   8. Select Confirm.
   Step 2 – Remove old Google IMAP credentials from Windows Credential Manager
   1. Open Credential Manager from the Windows Start menu (on Windows 10 this may be under Control Panel).
   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; these are the Gmail credentials.
   5. Select Remove for each MicrosoftOffice16_Data:OAUTH2 entry that corresponds to Gmail (there are typically two per Gmail account).
3. Re-add/reauthorize the Gmail account in Outlook
   • Start Outlook again.
   • If prompted to sign in to Google, complete the sign‑in and, when shown the permissions screen, ensure the Gmail access box is checked:
     • “Read, compose, send, and permanently delete all your email from Gmail.”
   • Allow Outlook to resync folders; the “synchronizing subscribed folders” error should stop.

If the error persists, also verify in Gmail settings (via the Google account) that IMAP is enabled, as missing IMAP can also cause the “We weren’t able to set up your Google account with IMAP” and related sync issues.
