Microsoft Retired Teams and Google Workspace Calendar Sync: What to Do Now (2026)

Quick Answer: Microsoft retired calendar syncing between Google Workspace and Microsoft Teams in October 2026 and offers no replacement sync; the Teams Meeting add-on only adds meeting links. For two-way Google ↔ Outlook or Microsoft 365 calendar sync, use a sync tool; SYNCDATE does this per person or for a whole team on one bill. We make SYNCDATE, so weigh this as our view; Microsoft facts are quoted from its own documentation, read 3 November 2026.

If your company keeps email and calendars in Google Workspace and uses Microsoft Teams for meetings, a feature you relied on is gone. Microsoft ended the calendar sync that the Teams admin set up between the two. Your Google Calendar and your Teams calendar no longer update each other. This page explains what Microsoft retired, what it left in place, and how to keep a Google calendar and a Microsoft calendar in step without it.

What Microsoft retired

Microsoft's own documentation page on calendar syncing with Google Workspace says: "Beginning October 2026, calendar syncing between Google Workspace and Microsoft Teams will no longer be supported." It adds: "Calendars that were previously setup for syncing will no longer sync."

The same page names a second loss for admins: "Admins will no longer be able to manage their custom domain or calendar sync from the Admin app within Teams."

The Microsoft 365 Message Center carried the notice as MC1462469, titled "Microsoft Teams and Google Calendar sync retirement". It was published on 26 August 2026 for the service Microsoft Teams. Microsoft tagged it Major change, Retirement, User impact and Admin impact. Microsoft gives the month October 2026 for the retirement and lists "Act by: Oct 1, 2026". There is an archive copy of the notice if you cannot reach the Message Center.

As of 3 November 2026, the retirement month has passed. Microsoft named October 2026 and asked admins to act by 1 October 2026. We do not know the exact day it switched off for your tenant. Per Microsoft's statement, calendars that were matched through the Admin app have stopped syncing. Do not rely on any event that still seems to cross over.

Who was affected

The notice names the group: "Organizations currently using the calendar syncing capability between Microsoft Teams and Google Workspace through the Admin app in Teams."

In plain terms, this was the feature for businesses whose email and calendars live in Google Workspace while they use Microsoft Teams for meetings. A Teams admin matched Google accounts to Teams accounts. After that, Google Calendar and the Teams calendar stayed in step, so a meeting booked in one place showed as busy in the other.

If your people use Outlook or Microsoft 365 mail and calendar, and Teams on top, this retirement did not touch you. The same is true if you only use Google Calendar and join Teams meetings by link. It hits the mixed setup: Google for mail and calendar, Teams for meetings.

What Microsoft told admins to do

The notice asks admins for three things:

• Notify affected users that calendar synchronization will stop in October 2026.
• Retrieve and retain any account matching information from the Admin app in Teams before the retirement date.
• For users who need to schedule Teams meetings from Google Calendar, recommend the Microsoft Teams Meeting add-on for Google Workspace.

Microsoft says the retirement lets it focus on "supported integration experiences, including the Microsoft Teams Meeting add-on for Google Workspace". The add-on is in the Google Workspace Marketplace.

Microsoft announced no replacement sync feature. That is the part to plan around. The add-on is a different tool for a different job.

The Teams Meeting add-on is not a replacement

The Teams Meeting add-on creates a Teams meeting link from inside Google Calendar. You add it to a Google event, and the event carries the join details. That is useful, and it is the right answer to "can I still create Teams meetings from Google Calendar". The answer is yes.

The add-on does not copy events between calendars. A meeting in your Google calendar does not appear in a Microsoft calendar because of it. A meeting in a Microsoft calendar does not block time in Google. So the add-on solves the meeting-link problem, and the double-booking problem stays open.

The native options that remain

After the retirement, these are the built-in ways to get one calendar's events into another. Each has a limit, and none is two-way.

• The Teams Meeting add-on for Google Workspace. It adds a Teams link to a Google Calendar event. It copies nothing.
• A published calendar address. In Google you publish a calendar as a secret iCal address and subscribe to it in Outlook. Or you publish from Outlook and add it in Google with "From URL". This is one-way and read-only. The receiving calendar refreshes on the provider's own schedule, often after hours.
• Sharing a calendar with a person. Sharing works inside one provider. It does not cross from Google to Microsoft 365.
• Doing it by hand. You invite yourself, forward invites or re-enter events. This works for a handful of events and fails the first week you are busy.

A subscribed iCal calendar is the closest to a free fix. It shows your Google events in Outlook so colleagues see you as busy. It cannot carry an event back, and a change can sit unseen for hours. If someone books you in Outlook, Google does not know. For a light, one-way need that is acceptable. For a calendar people book into on both sides, it is not.

What a replacement has to do

The retired feature kept two calendars in step in both directions. Any replacement has to match that, or you will trade one problem for another. Check these points before you pick a tool:

• It works both ways, so an event added on either side shows on the other.
• It updates fast enough that two people do not book the same slot.
• It lets you choose what the copy shows, so private details stay private.
• Each person can set it up without a tenant-wide change.
• A company can run it for many people on one bill.

How SYNCDATE covers it

SYNCDATE connects Google Calendar and Outlook or Microsoft 365 through their own APIs. You pick two calendars and a direction. Mirror copies in both directions. Push copies one way. The direction guide explains the choice.

New syncs copy events as Busy. A two-way Mirror between calendars you own keeps the real titles. You can change either before you start. Google and Outlook changes usually reach the other calendar in under a minute. A safety poll every 15 minutes on paid plans, and every 2 hours on Free, catches anything a notification misses.

Each person connects their own accounts, so nobody needs the Teams admin for this. A Microsoft 365 tenant may need an IT admin to approve the app first. The workspace admin page explains the approval.

This does not give you Teams meeting links inside Google Calendar. Keep the add-on for that. SYNCDATE only keeps the calendars in step. The two work side by side: the add-on creates the meeting link on the Google event, and SYNCDATE copies the event to the Microsoft calendar.

For a whole company

The Teams sync was an admin feature, so many companies will want an admin answer. The Team plan gives every seat Pro limits on one bill, with five seats minimum. The admin sets sync rules for the team once and never sees members' events. People then connect their own calendars under those rules.

That matches how the old feature was used: one person in charge, many people covered. The difference is that each member's events stay with the member.

What to do this week

• Ask your Teams admin whether they saved the account matching information Microsoft asked them to retrieve. It lists which Google account matched which Teams account, so it tells you who relied on the sync.
• Tell affected people that the automatic sync has ended. Say that new meetings will not cross over until they set up another method.
• Install the Teams Meeting add-on for anyone who books Teams meetings from Google Calendar.
• Pick a sync method for the calendars people need in step. Use an iCal subscription only for one-way viewing. Use a sync tool where people book on both sides.
• Check for gaps. Look at the week ahead in both calendars and fix any event that is missing on one side.
