The company I work for is considering migrating to an on-site Exchange server, (we already run SBS 2008) but there is one issue I need to get verification on before we move ahead.
Currently, we are using a hosted IMAP service with Horde webmail. When remote users are logged in and their IP address changes, their webmail session terminates and they are forced to log back in again, which causes all manner of grief when they are overseas and using a low quality 3G service provider.
Does Outlook Web Access suffer from the same problem? How does it authenticate sessions? By IP address, or cookies, or some other means?
TIA!
