OK, on our Exchange Webmail, the Certificate has expired meaning people are asked if they want to continue, and also Exchange Everywhere (rpc) no longer seems to work.
What is the best way to resolve this as:
a: I dont know who the best value for money is on a certificate and what type I should buy
b: I dont know how to install it, usually I would though IE, however on IIS, there appears no way of adding it for that particular section.
Thanks in advance,
