Hello,
I'm facing a strange problem where messages remain in submission queues with status "Active" and do not get delivered to the mailboxes.
Since the queue is a submission queue, everything points to the categorizer. Moreover, those messages suddently get delivered after half an hour appoximately.
There are many transport rules in the organization that are complex and long. This is causing the transport service to take one and a half minutes to start. Can these rules be the cause of the problem?
Furthermore, the messages that get stuck in the submission have certain recipients that are used in the transport rules in order to decide to act on the message or not.
Let me give an example of the rules:
If the message is from [long list of addresses] and the recipient is [member of distribution group or mailbox] then remove the message.
And one last thing, the actions on the rules are BCC and Remove. As far as I know, the remove action has to be the only action on a rule, those rules were probably migrated that way, should I update them and use the redirect transport action?
Thanks in advance,
Christos
