现在我收到两个客户的反馈,他们用户的手机outlook升级新版本以后无法更新邮件。后端服务器是Exchange server 2019 最新的CU及SU/HU ,这个有明确的ISSUE么?

    The issue of Outlook mobile apps being unable to refresh emails after an update could be related to several factors. One potential cause is the compatibility of the app with the Exchange Server version. Since you mentioned that the backend server is Exchange Server 2019 with the latest Cumulative Update (CU) and Security Update (SU/HU), it is important to ensure that the server is configured to support the latest TLS protocols. Outlook for iOS and Android requires TLS 1.2 or later for secure connections, and if the server is still using deprecated versions like TLS 1.0 or 1.1, this could lead to connectivity issues.

    Additionally, if the TLS certificate on the server is expired or not installed correctly, it can also prevent the Outlook app from refreshing emails. It would be advisable to check the TLS settings and the validity of the TLS certificate on your Exchange Server.

    If the problem persists, consider checking for any known issues with the specific version of the Outlook app that was updated, as there may be bugs or compatibility issues that need to be addressed by Microsoft.

    感谢您在 Microsoft Q&A 论坛中提出问题。

    为了更好地协助您排查该问题,我需要一些补充信息:

    受影响的移动设备是哪些?该问题是同时发生在 iOS 和 Android 设备上,还是仅限于其中一个平台?

    用户在刷新或同步邮件时具体表现是什么?例如:

    • 一直显示加载或转圈但无法完成同步
    • 无法接收到新邮件
    • 是否出现了具体的错误提示,例如“无法连接到服务器”或“无法同步您的电子邮件”等?

    用户是否可以通过 Outlook 网页版(OWA)桌面版 Outlook 正常访问邮件?

    如果适用,用户是否已经检查过设备的 操作系统是否为最新版本,以及是否存在未授予的应用权限(例如后台刷新、通知权限等)?

    在一些类似的案例中,该问题可能与 Exchange ActiveSync 设置防火墙配置 有关。请您在此期间协助检查一下相关设置。同时,请您参考以下资料:
