Latest Message<\/th>\nTitle: Users may see a banner in the Microsoft Teams desktop app mistakenly stating they are on an old version <\/p>\n

User impact: Users may see a banner in the Microsoft Teams desktop app mistakenly stating they are on an old version. <\/p>\n

More info: The error states “You’re using an old version of Teams. Update the app to continue using Teams on this device”. This banner appears in the Microsoft Teams desktop app regardless of the version being used. <\/p>\n

Current status: We’ve identified that the service that detects the version of Microsoft Teams a user is using is mistakenly detecting new versions as old, resulting in impact. We’re updating the configuration of this service to prevent theses false detections and remediate impact. <\/p>\n

Scope of impact: Users on newer versions of Microsoft Teams may be impacted. This information may be updated as our investigation continues. <\/p>\n

Root cause: The service that detects the version of Microsoft Teams a user is using is mistakenly detecting new versions as old, resulting in impact. <\/p>\n
