Update 21/05/26 – 11:05 am (IST): Google has identified the root cause of the ongoing authentication and sync failures affecting Android users connecting Microsoft Exchange Online accounts to the Gmail app.

According to the latest incident report on the Google Workspace Status Dashboard, a new version of the Gmail Android app containing a permanent fix is currently rolling out. Users who install this latest update will be able to log in and sync their accounts successfully.

In the meantime, anyone still waiting for the app update to hit their device can continue using the Microsoft Web App as a temporary workaround.

Update 18/05/26 – 01:00 pm (IST): Google has officially acknowledged the ongoing authentication problems affecting Android users. According to an incident report on the Google Workspace Status Dashboard, the engineering team is actively investigating the issue preventing users from logging into Microsoft Exchange Online via the Gmail app.

While they work on a permanent fix, Google’s official workaround advises affected users to use the Microsoft web app to access their inboxes.

Update 12/05/26 – 09:17 am (IST): Fresh comments under Microsoft’s Exchange Team post suggest some of the confusion may not be limited to Gmail users alone. Admins say Microsoft’s own PowerShell command for spotting outdated ActiveSync clients can also pull up old Outlook for iOS and Android entries, even though Microsoft has separately said Outlook Mobile is not affected by this Exchange Online change.

Another admin pointed out that the command also does not tell you whether those devices are still actively syncing, which makes the results harder to act on. A Microsoft employee acknowledged a community-made script using Get-MobileDeviceStatistics as a “nice example,” so right now it looks like some IT teams may need deeper reporting to figure out which stale records actually matter and which ones can be ignored.
