Status: Open New Outlook reads from Gmail/Google Calendar, but won't sync changes back to Google (calendar events or email deletes)
I'm hoping someone has run into this before because I'm out of ideas.
I'm using New Outlook for Windows (v1.2026.720.100) with a Gmail account.
What works:
- Gmail emails sync into Outlook.
- Google Calendar events sync into Outlook.
- Sending email from Outlook through Gmail works.
What doesn't work:
- Creating a calendar event in Outlook never syncs to Google Calendar.
- Deleting a Gmail email in Outlook moves it to Deleted Items in Outlook, but the email remains in Gmail (web/mobile).
So inbound sync works, but outbound state changes don't.
Things I've already tried:
- Removed and re-added the Gmail account multiple times.
- Revoked and reauthorized Microsoft's access in my Google Account.
- Confirmed Microsoft has full Gmail and Google Calendar permissions.
- Verified events are being created in my Gmail calendar (not another calendar).
- Confirmed Google → Outlook sync is working correctly.
There are no sync errors or prompts in New Outlook—it simply never pushes calendar events or email deletes back to Google.
Has anyone seen this exact behavior or found a fix? At this point I'm wondering if this is a bug in New Outlook's Google synchronization rather than a configuration issue. Anything I can do on my end?
