Requirements

  • Windows 8 or 8.1

  • Windows Server 2012 or Windows Server 2012 R2

  • Windows 7 Service Pack 1 (SP1)

  • Windows Server 2008 R2 SP1

  • Microsoft .NET Framework 4.5 or 4.5.1 and either the Windows Management Framework 3.0 or the Windows Management Framework 4.0

  • Verify the service account has a mailbox, and is not hidden in the Global Address list

Microsoft Exchange Online

Microsoft Exchange Online message throttling policies set bandwidth limits and restrict the number of processed messages. Throttling is enabled by default in Microsoft Exchange Online. Currently you cannot set policies to disable throttling in Exchange Online; for details, refer to the Microsoft Outlook dev blog. Barracuda is working on a solution to provide this option in the future.
