Can I use my current SAN certificate for SMTP?
I currently have a SAN certificate in place for Exchange and it works for POP3 and OWA, though when setting up POP3 accounts in outlook I receive the certificate warning message..alot. When I run the "get-exchangecertificate" cmdlet the services currently on my thumbprint for my certificate are "I, P, W" and "I, S" on the default exchange certificate. How can I get the S onto my created certificate and will this allow outlook to stop warning me?

Also for your popr users getting cert erros make sure that the send connector and recieve connector have the same FQDN mentioned which the CERT is issued to

I tried running the same command earlier and after I enter the command the ">>" appears and nothing happens.

I looked on the Edge Transport server and there are 4 tumbprints of just "S" services. Probably from all the times a had re keyed the certificate. None of the thumbprints match the ones on the Exchange server.

But this shouldn't matter for client access right?

Shouldn't all users have the same email signature?

You wouldn't let your users design their own business cards, would you? So, why do you let them design their own email signatures? Think of the damage they could be doing to your brand reputation! Choose the easy way to manage set up and add email signatures for all users.

So when you run the command

Enable-Exchangecertificate -thumbprint  (yours certificate thumb print) -services "smtp"

Does it throw any errors ?

I finally got it to work. I was trying to just enable the SMTP by running the command you gave. Nothing happened. What I did do that worked was using your command but including the other services ("POP, IMAP, IIS") with the command and is asked me if I wanted to overwrite the default SMTP Exchange certificate.

Enable-Exchangecertificate -thumbprint  (yours certificate thumb print) -services "POP,IMAP,IIS,SMTP"

Here is the screenshot of the process.

Thanks.
