Microsoft が提供する Microsoft 365 のサービス正常性(TM295750)にて、一部の Android 11 のデバイスで Microsoft Teams の通話や会議の受信および発信ができない SI(サービス インシデント)が発生していることを発表しています。

この問題の影響を受けている Android 11 のデバイスでは、ユーザーが Microsoft Teams の通話や会議の発信が行えず、着信した通話や会議が 5 ~ 10 秒後に切断されます。

現在は、Microsoft Teams のモバイル アプリのアップデートの配信を完了したことを確認しており、Google Play ストアより最新のバージョンにアップデートする必要があります。

この問題は、Android 11 向けの Microsoft Teams の最新バージョン(1.0.0.2021163901)に Microsoft Teams のネットワークにアクセスする機能に影響するコード上の問題が含まれていたことにより発生している問題になります。

今後は同様の問題が発生しないように検証やアップデートの手順を見直すとのことです。
