About 2 exchange certificates

Hey Experts,
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?
Please advise!
Kind regards,
Kim

my two cents

dont use self signed certs use Godaddy or competitor level wildcard certs and SSL your exchange EWS urls autodiscover etc from the one wildcard cert.

self signeds are for cowboys in my opinion. #1

Dear Wayne88,
There are no known services attached to the certificates, as shown in the screenshot.

Please confirm?
Kind regards,

I just checked and, no they don't end with that thumbprint.
Can I assume that it was my predecessor messing around trying to create a self-signed cert, having issues with the owa IIS not willing to cooperate (certification errors popping up), and that the decision was made to get an external authority to provide a valid certificate?
