===== Cause ===== This issue can occur if the mail item(s) to be restored exceeded the message size limits (MaxReceiveSize) setting configured for the restore destination Exchange server. ===== Resolution ===== To resolve the issue, temporarily configure the maximum message size that can be received by recipients in the organization (MaxReceiveSize) to unlimited, before performing the restore.
  1. Check on the current "MaxReceiveSize" setting of the restore destination Exchange server, enter the following command in Exchange PowerShell:

    Get-TransportConfig | fl
    For more details on the Get-TransportConfig cmdlet, refer to - https://docs.microsoft.com/en-us/.../get-transportconfig

  2. Temporarily modify the "MaxReceiveSize" setting to unlimited, enter the following command in Exchange PowerShell:

    Set-TransportConfig -MaxReceiveSize unlimited
    For more details on the Set-TransportConfig cmdlet, refer to - https://docs.microsoft.com/en-us/.../set-transportconfig

  3. Perform the MS Exchange Mail Level again afterward to see if the problem persist.
Important: Revert the "MaxReceiveSize" setting to its original value afterward, or modify the setting according to the requirement of the mailbox users. ===== Keywords ===== exch, mail, brick, restore, restoring, exchange, ex-change, MAPI_E_CALL_FAILED
