exchange 5.5 and nokia 9210
i've got problem with reciveing mail from MS Exchange 5.5 to Nokia 9210. I can dial-in with 9210 in to the network, i have configured proxy settings, internet works ok. i can send e-mail, but when i try to check content of mailbox on exchange server, there is an error. In exchnge's logs error message apears (user's alias and domain account is "tsan") :
"Logon attempt by URZ_MARSZ\tsan from 10.82.3.80 to tsan has failed: EcGetMailboxDN() call failed with error :requested mailbox is not available on this server. "
