Outlook Anywhere for Non-Domain Client
I'm having a problem connecting non-domain client to exchange 2010 using outlook anywhere 2007.
1. I tried to vpn to our network and it successfully connect outlook anywhere to our exchange server, but if i disconnect to vpn i got this error "the action cannot be completed. The connection to microsoft exchange is unavailable.Outlook must be online or connected to complete this action."
2. Our OWA is working fine for the external email users.
3. Tried the testexchangeconnectivity and got this error..
