I had several "Expired Certificate" messages come up in the server's event logs, so I used the "Fix my network" wizard to try and address them. The new certificates were created, but the errors persisted. I went into Administrative tools > Certificate Authority and 'revoked' the expired certificates. The errors continued. I went into IIS > [server] > Sites, right-clicked on Default Web Site, and selected Edit Bindings. I scrolled down to https|443|* and clicked the Edit button. In the SSL certificate section (with the "remote.[server].com" site), I clicked the View button. It listed the expired certificate. Back in the Edit Site Binding window. I clicked on the drop-down arrow for the SSL certificate and chose a different "remote.[server].com" site. When I checked "View" it now had the correct, up-to-date certificate. This solved the certificate error messages that Outlook users were getting, but the expired certificate errors still showed up in the server's event logs. I'm at a loss as to what to do next to get rid of them. Help!
