Microsoft が提供する Microsoft 365 のサービス正常性(EX421831)にて、macOS のユーザーが Outlook for Mac デスクトップ クライアントで PW(パスワード)の入力が繰り返し求められる可能性があるアドバイザリが発行されていました。

なお、本事象は主にトルコ語が影響を受けていたことが確認されていますが、英語以外の言語にも影響があった可能性があります。

※ 英語を利用している場合、本事象の影響は受けていません。

そのため、一時的に主要言語を英語に設定するか、Outlook on the web を利用することでな回避策することができました。

現在は、最新バージョンの Outlook for Mac がリリースされたことにより、社内およびユーザー テストで、本事象が解決していることを確認しています。

今後は、影響が発生した URL 言語変換コードの検証を継続し、根本的な原因の把握と同様の事象の問題の防止に努めるとのことです。

この問題は、トルコ語または英語以外の言語を主要言語として設定している Outlook for Mac のデスクトップ クライアントにアクセスしようとした macOS ユーザーが影響を受ける事象になります。
