There are a number of obstacles which impede easy access to LAN Email. The remote software depends connection through the X.25 packet-switched network often connecting through 2 or 3 different networks. Navigation beyond one network is not always reliable.
Remote software is difficult to configure.
Remote requires that the entire user mailbox be downloaded. This means that one large Email attachment can mean stay online for up to an hour or more just to get correspondence. It is possible to set up in advance, accounts at the regional office, but they also suffer from limitations. Accounts can only be used in the Regional Office itself making the account less useful if the P.O. is doing a lot of traveling in the region. Two or more Email addresses then appear in STDA for the P.O., resulting in duplication and missed Emails.
