I have acquired a client with apx 200 mailboxes on Exchange 2010.
The Exchange server is in a .local domain, and has a public security cert with multiple names, including the .local
The cert expires in November coincidentally with the ending of public certs to be issued with a .local extension.
I have read conflicting information on what needs to be done... from renaming the domain (ouch), to adding another front end server, to just forget about it, didn't need the .local registered anyway.
Really afraid once the .local is no longer part of the cert, internal users will start getting the dreaded Outlook security prompt.
Any Exchange guru's who are familiar with this issue, and know what I'm facing?
