Upgraded from Exchange 2003 to 2010 a couple of weeks ago and everything seems fine, except one small detail;
Under Recipient Configuration when clicking "Mailbox", the list is empty. "There are no items to show in this view". All the other containers (Distribution Group, Mail Contact, etc) are OK and items are listed but not under "Mailbox".
When clicking "Recipient Configuration" (one level up) all items are listed, inclusive the mailboxes that are supposed to be under the "Mailbox" container... ..now how did that happen, and how can I fix it?
Thank you all in advance! :-)
