We are currently using an Exchange 2007 self signed certificate that will soon expire. Since we have a small amount of users that are getting a hub transport certificate error anyway, we just planned on replacing the self signed certificate with one from our own internal CA.
Is that a big deal? Should we look at an external CA instead? Would I need to remove the self signed certificate BEFORE installing the new certificate? Anybody else been through this? Enough questions? Thanks all, Rob
