I haven't dealt much with SBS Exchange / certificates.
This network is getting this popup recently. Clicking on details, I see the certificate expired a couple weeks ago - I think that's when the users started getting the error message.
Realistically, what is the argument for paying the money to get a new certificate vs. removing the old one ( any tips on how to do that)?
This is a location that is not concerned about security - everyone in the office knows everyone else's passwords / they don't change their passwords, they are really frugal.
How do I explain why they need / should spend the money for a new certificate (and who do you like getting them from?) or what's the downside of just removing the expired cert?
