We just migrated from IpSwitch's Imail 8.0 to Exchange 2003. We have encountered some minor challenges accessing Exchange via the internet.
1) We have several users using Windows Mobile devices from Verizon. We're having challenges configuring exchange to allow a windows mobile device to "Suresync" to the server.
a. What ports do we open on the firewall? (Sonicwall PRO 4060) (Currently we have port 25 open to this server)
b. Is there additional configuration required on the Exchange 2003 Server. RPC over HTTP ?
2) Outlook web access works internally. However, after opening port 80 to the exchange server it is not possible to access the page from the internet. Any thoughts ?
2) Is WINS absolutely neccesary in an Active Directory environment. Presently we are not using wins and everything(internally) is working correctly.
Thanks in advance....
