我有一个AD用户无法在手机上同步电子邮件。使用https://testconnectivity.microsoft.com进一步调查显示 Exchange ActiveSync返回了HTTP 500响应
具有完全相同AD组的其他用户可以正确同步。我已经三次检查他是否已正确输入他的域/用户/密码。什么可能导致这个问题/在哪里可以寻找更多的线索？
https://testconnectivity.microsoft.com的输出：
Attempting the FolderSync command on the Exchange ActiveSync session.
The test of the FolderSync command failed.
