Anyone run across this issue
We have a new environment with Server 2016 fully patched .net 4.6.2 & Exchange 2016 CU8 (but issue occurred on CU6 as well). I am seeing 90%+ cpu load on a VM with 8 CPUs, 24 GB of Ram. This environment only has 60 users so the load shouldnt be that high. They are all in online mode as they work out of Citrix. The 2 highest process at about 60% are the MAPIFrontEndAppPool & MapiMailboxAppPool
We have similar and larger environments with the difference between Server 2012 R2 and Exchange 2016 without any issues. Has anyone read about any issues with Server 2016 & Exchange 2016?
I have an open case with Microsoft but wanted to reach out and see if anyone has seen this in their environments.
