According to the error message, please run blew command to double check the health set on EXCH-MB02:
Get-ServerHealth -Identity "EXCH-MB02" -HealthSet "Outlook.Protocol" | FT Server,State,Name,AlertValue –Autosize
Please run Get-ServerComponentstate -Identity “servername” to check the state of server component, if the state is Inactive, please run below command to active relevant component:
Set-ServerComponentState <Identity> -Component “component name” -Requester HealthAPI -State Active
For second question, it can be ignored if there's no any transport issues in the productive environment.
For third question, it might be caused by mismatched configuration on the max receive size and transport size for receive connector. Please run below command to check:
Get-TransportConfig | FT MaxSendSize, MaxReceiveSize
Get-ReceiveConnector | FT Name, MaxMessageSize
If it mismatch, please run below command to modify the value of limitation:
Set-TransportConfig -MaxSendSize 25MB -MaxReceiveSize 25MB
Get-SendConnector | Set-SendConnector -MaxMessageSize 25MB
