hallow, I just created a few user accounts in exchange server 2007 and put then in group but these users can sent emails but they cants receive emails, I removed them from active directory then recreate them again in AD and make new mailbox in exchange server again and the same issue cant receive emails. I made another group and I put one of the user in that group but the same thing happen.
I have more than 1000 users and all working fine, and its internal mail.
thank u
