Been having random outlook drops on of the mailbox servers when I checked the logs I noticed the RPC service was throwing an errors stopping and restarting so I added this to the registry:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\MinimumConnectionTimeout DWORD value 120
that seems to have resolved the RPC service from stopping / erroring out / restarting but I keep getting the below error randomly which coincides with an outlook drop and reconnect for users:
