Hi, I've got a problem when I try to use CDOEXM to create a mailbox. We have a system test with windows 2000 that have got the AD and the Exchange. I'm running the code from a client machine, whith the aspx page. When I try to create a user account it works fine, but when I try to create a mailbox I receive the message: "An operations error occurred." e.g. - maibox.createMailBox(LDAP://MYSERVER/CN=MYRECIP,CN=First Storage Group,CN=InformationStore,CN=MYSERVER,_ CN=Servers,CN=First Administrative Group,CN=Administrative Groups,_ CN=Email Externo,CN=Microsoft Exchange, CN=Services,_ CN=Configuration,DC=MYDOMAIN) What's up?
