Update Teams mobile app by October or lose your calendar
A nice little summer job for someone
Microsoft has shortened the deadline for updating the Teams mobile app from late October to the start of October. Users of iOS and Android must update to avoid losing calendar access. The web and desktop versions remain unaffected. Automatic updates will likely handle the process for most users. Managed devices require administrator intervention to ensure an updated app is deployed.
Microsoft will disable EWS in Exchange Online on October 1, 2026, marking its retirement after feature updates ceased in 2018. Users with older versions will experience calendar loss once EWS is disabled.
