Performance counter updating error
Unauthorized Access Exception: Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange Server\v14\Transport' is denied. Ex Performance Counter.set_Raw Value(Int64 value) Last worker process info : System. Although CAS role has also service named Microsoft Exchange RPC Client Access I did not see this issue if CAS Role is installed on server without Mailbox Role.
The time service detected a time difference of greater than 5000 milliseconds for 900 seconds.
Otherwise, all mail flows through the Exchange 2013.
I don't believe this is connected to the presence of the 2007 install; I just thought I'd bring it up just in case.)Has anyone seen a similar issue?
If Ex Mon shows you high RPC requests from one user mailbox, open his mailbox and look for corruption in calendar.
Sort the calendar items by “list” and then by “size”.
