Similar to your prior post, I believe these are the same root cause.

There is a current Known Issue with Gmail and Yahoo accounts. Please try the workaround in this article, https://support.microsoft.com/en-us/office/users-get-errors-0x800ccc0e-0x800ccc0f-synchronizing-gmail-and-yahoo-accounts-in-classic-outlook-e5a7b684-7c5c-4848-ab2d-d48291451f67.

As another alternative, the steps to clear the credentials in Credential manager under Manual Workaround Step 2 in this article may also work, https://support.microsoft.com/en-us/office/unable-to-add-a-gmail-account-to-classic-outlook-4d9530c5-3f40-4e6d-9b45-4477f160828f.

Follow these steps to fix Outlook sync issues with a Gmail account:

Enable IMAP in Gmail
1. In a browser, go to Gmail.com and sign in.
2. Select Settings (gear icon) > See all settings.
3. Go to the Forwarding and POP/IMAP tab.
4. Under IMAP access, select Enable IMAP.
5. Select Save Changes.
Ensure folders are visible to IMAP
1. In Gmail settings, go to the Labels tab.
2. For Inbox, Sent Mail, Trash, and All Mail, make sure Show in IMAP is selected.
3. Optionally enable Show in IMAP for any other labels that should appear in Outlook.
Verify server settings in Outlook (if using manual setup) Use these values for the Gmail account in Outlook:
- Incoming mail (IMAP) server: imap.gmail.com, SSL required, Port 993
- Outgoing mail (SMTP) server: smtp.gmail.com, SSL required, TLS if available, Authentication required
- SMTP Port for SSL: 465; Port for TLS/STARTTLS: 587
- Username: full Gmail address
- Password: Gmail password (or app password if using that method)
Update Outlook to a fixed build (classic Outlook) Some Gmail sign-in issues in classic Outlook are fixed only in newer builds.
- For the error messages like “The browser or app may not be secure” or “We weren’t able to set up your Google account with IMAP…”, install a build that includes the fix:
  - Current Channel / Current Channel Preview / Beta Channel: Version 2404 (Build 17531.10000) or later
  - Monthly Enterprise Channel: Version 2407 (Build 17727.10000) or later
- After updating, retry adding or repairing the Gmail account.
If using an older Outlook build with the “Could not sign you in to Google – IMAP” error
- Make sure Outlook is at least Version 2008 Build 13127.20296, which contains a fix.
- If stuck on an older build, enable optional connected experiences as a workaround:
  1. Open Outlook.
  2. Select File > Office Account.
  3. Under Account Privacy, choose Manage Settings.
  4. Check Enable optional connected experiences.
  5. Restart Outlook and repair or re-add the Gmail account.
Refresh Outlook after changes
- After adjusting Gmail IMAP and label settings, allow up to 15 minutes for sync to refresh.
- In Outlook for Windows, use Send/Receive All Folders or restart Outlook to force a refresh.

If repair still fails after these steps, remove the Gmail account from the Outlook profile and add it again using the automatic account setup, ensuring IMAP is enabled and server settings match the values above.
