  • If the user is an administrator, i.e., if he belongs to certain privileged groups like Domain Admins or Organization Management, then make sure that permissions inheritance is enabled for the user and try again.

    Longer term, consider following security best practice and assign a separate non-mailbox-enabled for administrative tasks and remove the regular account from administrative groups.

  • Hi,

    To troubleshooting your issue, please run below command to check:
    1. Ensure ActiveSync feature is enabled, also check the allow and block device list:
    Get-CASMailbox | FL CASEnable,AllowDeviceID,BlockDeviceID,ActiveSyncMailboxPolicy
    2. Check the ActiveSync Device and its status of problematic mailbox:
    Get-ActiveSyncDevice <Mailbox>
    Get-ActiveSyncDeviceStatistics <Mailbox>

    If ActiveSync feature is disabled, please enable it and ensure current device ID not list in BlockDeviceID list.

    If this issue remain exists, check the IIS log (C:\inetpub\logs\LogFiles\W3SVC1) to find more information.
