Hello, I have a user when she tries to forward an email to a group of users the server hangs, Server: Exchange 2003, Windows 2000, SP3 Client:Outlook 2003, Windows XP, SP2 (batched up to date) The user tries to forward chain letters usually less than 1 Mbyte to a local distribution list she created on her machine, the list includes around 110 users mixed, some from the domain and some from outside, all the email exists she doesn't receive an NDR for that list. when she tries to forward an email the outlook of every body else in the organization says Connection to Microsoft Exchange lost, Trying to connect to Microsoft Exchange server, this happens for few seconds, and then the outlook retrieve the connection and the email from that user arrives. This do not happen unless that user is forwarding emails to that group, if she is sending an email to one person, the server doesn't suffer. Nothing shows at the event log or from MOM. I tried moving her mailbox to another physical disk with the same symptoms. Any one expereinced such problem? thanks, r.
