the problem was started, when one of the Ev system mailbox for a specific Exchange server has been moved from that exhange server to another , since that the archiving options work exteremly slow for all the users that has mailbox on that exchange server, and based on technot found it on symantec ,one of the solution is to move the EV system mailbox back to the original exchange server but unfortunately that didn't solve our issue.
so please can anyone help me to solve this problem?
