Does Quest Collaboration Services support Exchange Server 2019?
解决办法
Quest Collaboration Services version 3.10.1 was tested and found to be working with Exchange Server 2019 with same prerequisites as Exchange Server 2016, i.e. Outlook 2013 32-bit, Outlook 2019 32-bit version installed on QCS server rather than MAPI CDO, which Exchange 2016 and later no longer supports.
