Hi Patrick, I assume that the second sentence is around the wrong way? I think I understand what you're doing now, but why its doing it is hard to say. Obviously it isn't default behaviour. The only thing I can think of, if the AD exchange settings are correct, is some type of client or server based rule set on that user. Worth a check, go into outlook, tools, rules wizard and see if any are set. Else you'll need someone elses help.

From the exchange system manager i did the message tracking i found out the mail send out from user@xxxxxxx to user@xxxxxxx it will auto send a mail locally. i had checked active directory for user basu account those delivery option and restriction is same as other users. If i send from usera@xxxxxxx to user@xxxxxxx there is no problem at all.
