Gmail outage: Exchange ActiveSync is working again
The email processing of Exchange mailers in Gmail was disrupted for weeks. Google has resolved the issue without further notice.

In mid-December, it became known that Google's email app Gmail was having problems with Exchange ActiveSync (EAS). Emails could no longer be retrieved and processed correctly. Affected were counterparts to the Android app that use EAS for message exchange – such as Exchange, Tobit, or Zimbra. Google developers have now apparently silently resolved the issue.
In December, Google suggested uninstalling updates for the Gmail app as a temporary countermeasure, which made emails available again via EAS. Since then, there has been silence on the issue. In Google's IssueTracker, signs have now multiplied that the issue has been resolved without further announcement.
New client version or server-side fix
It is currently unclear what exactly fixed the error. One user reports in the IssueTracker that the Gmail app in version 2025.12.01.843385623 has corrected the faulty EAS synchronization for them. Other discussion participants explain that on December 12th, the sync problem was resolved without a further app update. Several users in the forum echo this sentiment – for example, with the version of Gmail 2025.11.17.834797744, which was current up to that report, message retrieval and processing works again for them.
However, isolated users continue to report similar issues. For example, contacts are still not appearing. This can possibly be corrected by clearing the cache of the internal contacts app in the Android apps.

Since mid-November, the first affected users have reported the error to Google in the IssueTracker. They described the symptoms as mails, contacts, and calendar entries in Gmail sometimes being synchronized but then occasionally appearing empty. This occurred with the use of the Exchange ActiveSync protocol for exchange with the mail server. The Gmail app in version 2025.09.15.810231445 was the last one with which synchronization still worked – which even prompted Google to suggest uninstalling updates as a temporary solution. Those who followed this tip should now reinstall the available updates and check if data exchange still works.
