Microsoft が提供する Microsoft 365 のサービス正常性(OD286672)にて、OneDrive 同期クライアントにサインインしようとすると真っ白な画面でフリーズすることがある 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。

この問題は、Microsoft Exploit Protection EAF (Export Address Filtering) 機能を有効にして、2021 年 9 月のセキュリティ更新プログラムをインストールしたユーザーにて影響する可能性があります。

なお、管理者が [Windows セキュリティー] – [アプリケーションとブラウザーの制御] – [エクスプロイト保護の設定] – [プログラムの設定] – [OneDrive.exe] – [エクスポート アドレス フィルタリング(EAF)をオフにする] を選択することで影響を軽減できる可能性があります。

また、KIR(Known Issuer Rollback)を使用して、この問題を軽減することができるとのこと。

なお、影響を受ける更新プログラムをインストールして問題が発生している企業の管理対象デバイスでは、利用可能な MSI ファイルを経由してインストールされる特別なグループ ポリシーをインストールして構成することで軽減できるとのことです。

  • ・Title : Users will see a frozen white screen when attempting to sign into the OneDrive for Business sync app
  • ・User Impact : Users will see a frozen white screen when attempting to sign into the OneDrive for Business sync app.
  • ・More info : This issue might affect users who have the Microsoft Exploit Protection EAF (Export Address Filtering) feature enabled and have installed the September security updates.
  • We’ve confirmed that users with Mobile Device Management (MDM) enabled devices can add the following reg key as a workaround :
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides /v 2767781516 /t REG_DWORD /d 0 /f
  • We’ve also confirmed with affected users that disabling Export Address Filtering (EAF) is a potential workaround to alleviate the impact. Admins who wish to do so can navigate to Windows Security > App & Browser Control > Exploit Protection Settings > Program Settings > OneDrive.exe > Turn off Export Address Filtering (EAF) and mitigate the impact.
  • ・Alternatively, this issue can be mitigated using Known Issue Rollback (KIR) : https://techcommunity.microsoft.com/t5/windows-it-pro-blog/known-issue-rollback-helping-you-keep-windows-devices-protected/ba-p/2176831.
  • ・For enterprise-managed devices that have installed an affected update and encountered this issue, it can be mitigated by installing and configuring a special Group Policy installed via an MSI file available for :
