Hey folks We had a problem with our antivirus-software (trendmicro) and exchange, so we had to re-create the SystemMailBox on our Exchange2k I did it like its shown here : http://support.microsoft.com/default.aspx?scid=kb;%5bLN%5d;316622 I did it like method 1 Ok, so far so good. My problem now is, that i cant create new user in my ad. Ok, actually i can create a user, with its mailaccount,too. But 1) you cant login with outlook2k 2) this user has no email adresses assigned 3) in the securitytab of the mailbox from the new user there is only "self" in it (there should be many more) I´ve searched for system in my ad, and found 2 user: the old and the new systemMailbox. The strange thing is: the new on is deactivated, the old one is not. And in the ESM both mailboxes are connected! What now? I really got no idea. Please help :-( Mit freundlichen Grüßen / Best Regards Marco Zentarra Systemadministrator ONLine Distributions GmbH Heinrich-Hertz-Str. 4 D-59423 Unna Tel. +49 / 2303 / 98601-305 Fax +49 / 2303 / 98601-601 eMail: mailto:marco.zentarra@xxxxxxxxxxxxxxxxxxxxxxxxxx http://www.communication-companies.de <http://www.communication-companies.de/>
