My Microsoft Exchange 2007 self-signed certificate will soon expires.
So, I have to renew it (... New-ExchangeCertificate -GenerateRequest ... etc.)
For the moment, it will be a self-signed certificate again.
But, We have since few months, new Android smartphone devices with ActiveSync accounts, using SSL.
So, what are the messages we can wait on these devices, after the certificate's renewal?
I would like to warn users from potential messages.
