PopDeepTestProbe Issue

Question

I've recently built two Exchange 2019 servers in a DAG to replace our 2016 servers which are in their own unique DAG. They are not yet active but are ready with the exception of an Exchange HealthSet failing on one of the servers.

Running Get-ServerHealth -Identity 'Server' -HealthSet 'POP.Protocol' shows the PopDeepTestMonitor is Unhealthy.

Running Invoke-MonitoringProbe -Identity:"POP.Protocol\PopDeepTestProbe" -Server:Server | fl returns "WARNING: No mailboxes were found to use in the DeepTest probe."

I've tried rebooting the server multiple times along with recreating the Exchange monitoring mailboxes multiple times. Nothing has solved this issue. Does anyone have ideas?

I'm also seeing this issue now.Running Get-ServerHealth -Identity 'Server' -HealthSet 'ActiveSync.Protocol' shows the ActiveSyncDeepTestMonitor is unhealthy. &nbsp;If I run Invoke-MonitoringProbe -Identity:"ActiveSync.Protocol\ActiveSyncDeepTestProbe" -Server:Server| fl I receive the below error messages.Error &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;: Index was out of range.
