Exchange 2019 is currently not supported.  I believe the timeline for support isn't until next year, 2021.  I would recommend checking with support later in the year to see if this has changed.

Hello,

Have you any news about the support of Exchange 2019 ?

We are waiting on it to finish to migrate from Exchange 2013 to Exchange 2019.

Thank you,

Regards,

Emanuel
