my new outlook is not syncing from my gmail account

Question

Outlook is not syncing with Gmail... New email doesn't show up for hrs or not at all

Answer 1

Hi Michael Legato,

Welcome to Microsoft Q&A.

When Gmail mail arrives late (or not at all) in Outlook, it’s commonly related to the Google sign-in connection needing a refresh, background sync being interrupted, or a large Gmail folder set (especially All Mail) taking longer to sync/index.

Please try these in order:

1) Refresh the Google connection

• Close New Outlook.
• Google Account > Security > Your connections to third-party apps & services > remove Microsoft apps & services.
• Reopen New Outlook and sign in/add the Gmail account again.

Note: This doesn’t delete any Gmail mail—only Outlook’s authorization to access it.

2) Clear cached credentials (forces a fresh Google sign-in)

• Open Control Panel > Credential Manager > Windows Credentials.
• Look specifically for entries such as:
  • MicrosoftAccount:user=… (associated with your Gmail sign-in), and/or Generic Credentials that mention com.microsoft.Outlook
• Remove only those Outlook/Gmail-related entries, then restart New Outlook and sign in again.

Disclaimer: Avoid deleting unrelated credentials (VPN, other apps, work/school accounts) unless you’re sure they relate to Outlook/Gmail.

3) If your Gmail mailbox is large (reduce “All Mail” IMAP load)

If you have a big archive (tens of thousands of emails) and All Mail is syncing, Outlook may lag while it syncs/indexes. You can stop All Mail from being exposed to IMAP:

• Open Gmail on the web > Gear icon > See all settings
• Go to Labels
• Find All Mail and uncheck “Show in IMAP”
• Restart New Outlook

Note: This can significantly improve sync performance, but archived mail may not appear under an “All Mail” folder in Outlook (it remains available in Gmail on the web).

4) Repair / Reset (last resort)

• Windows Settings > Apps > Outlook (new) > Advanced options > Repair.
• Use Reset only if needed.

Disclaimer: Reset clears New Outlook’s local app data and you may need to re-add/reconfigure all accounts in New Outlook (not just Gmail). It won’t delete emails from Gmail, but it does remove the app’s saved setup.

Please let me know if this proves useful to you or if you would like further assistance.

I'm looking forward to your reply.

If your new Outlook is not syncing with your Gmail account, there are a few steps you can take to troubleshoot the issue:

1. Check Gmail Settings: Ensure that your Gmail account is set up to allow access from Outlook. You may need to enable IMAP in your Gmail settings.
2. App Password: If you have two-factor authentication enabled on your Google account, you might need to generate an app password specifically for Outlook. Use this app password instead of your regular Gmail password when adding your account to Outlook.
3. Account Configuration: Make sure that your Gmail account is properly configured in Outlook. You can refer to the instructions on how to add your Gmail account to Outlook, ensuring you follow the correct steps.
4. Check for Updates: Ensure that your Outlook application is up to date, as updates can fix bugs and improve functionality.
5. Re-add the Account: Sometimes, removing and then re-adding the Gmail account in Outlook can resolve syncing issues.

If the problem persists, you might want to check for any known issues with Gmail and Outlook connectivity, as changes in authentication methods by Google can sometimes affect syncing.
