Messages awaiting directory lookup large when restoring emails

On a day to day basis, this queue is fine.  Email never queue's up.  

However, we use GFI mail archiver and sometimes have to restore large amounts of email and that mail sits in the queue for a long time and slowly goes out.  Last night at midnight, I restored 8000 emails to a single mailbox and it just got finished at 10:20 AM.

Is there something wrong with the way I have setup Exchange?  Why are the mails taking so long to work through the queue?  Any help is greatly appreciated!

When sending mail the Exchange Categorizer will connect to the global catalog server to perform LDAP queries. If the global catalog server is unavailable or if the response is slow then the messages may remain in the "Messages awaiting directory lookup" queue..

I looked at both kb's and I am not sure if they apply to my situation.  Under normal conditions, the queue is always empty.  It's just when I push a large amount of messages from my archiving program does this occur.  Is that natural behavior for 3000+ messages?

What if a lot of these messages have 2-4mb attachments, will that increase the time?

3000+ mails with 2 - 4 MB attachments is certainly a load on server but it wont last for hours... to understand the exact reason you need enable the diagnostic logging.

Enabling diagnostic logging will fill up your logs, so make sure that you have set appropriate log file size so that you wont miss any other valid logs. Else enable logging and push the messages to reproduce the issue..
