We would like to migrate our Exchange 2010 environment to Exchange 2013. we currently use the Exchange 2013 server only with test mailboxes and to receive mail from outside the company. but since we changed it, the following event log messages appeared in the monitoring log.
The total number of messages in shadow queues exceeds 75000
but when we check the queue in the exchange toolbox we can't see any messages in one the Shadow queue's.
further we don't have any problems with sending or receiving mails.
How can we resolve this issue.
Vincent
