I have inherited a small business customer who's only server is a SBS2011 (25clients).
The SBS on premise exchange server is heavily used, and as it has been some time I've still had to maintain an exchange 2010 I've lost a bit of knowledge about these inhouse mailservers.
I've noticed 2 warning events popping up from eventvwr with eventid 26: exchange web services, informing me that 2 exchange certificates will be expiring soon.
When I check the services they are used for, it says they are used for nothing. (check attachment)
I'm someone who likes this to be as clean as possible, so can I just delete these?
Or will I need to renew? And if so, whatfor?
