Hi,

maybe it is back pressure? How much free hdd space you have, in %, as well as RAM and CPU usage? Any errors in event viewer?

Regards,
Ivan.
I'm with Ivan - probably back pressure, so check your free space on the system drive of the Exchange server (or other hard drive where Exchange is installed if not the system drive). Also check the Event logs - if it is back pressure you'll probably see some warning events indicating what is causing the issue.
thanks , I found the problem in GFI after remove it all things working fine
