Outlook anywhere

Well, you haven't given us much to go on. No error messages, no details of your network topology.

So I'll start with a simple suggestion. Use Microsoft's remote connectivity analyzer tool. It has a test specifically for Outlook Anywhere. That will at least help us know what questions to ask...

I did as requested and loaded the SBSCERTIFICATE.CER
then put the details into my computer

and I still get a message:
"the action cannot be completed. The connection to MS Exchange is unavailable. Outlook must be on line or connected to complete this action."

(Taking note that the connection to Outlook works with the VPN connected)

The settings of the email in the connections part were:
connect using  my local network - TICKED
Connection to MS Exchange using HTTP - TICKED

Exchange proxy settings are:
https:// remote.mydomain.com
connect using ssl -TICKED
(also tried  puting a tick in  "Only connect to proxy servers that have principal name etc" with the line "msstd:remote.mydomain.com")

Used BASIC AUTHENTICATION

Got it work. Was putting the certificate in wrong place.
