Hi All!

We have Exchange server 2003 with almost 2000 users, when we start the server, everything works fine for half an hour, and then outlooks shows connected to Microsoft exchange, but nobody gets email, or when they send emails, it stuck in Queue, Please let us know what are the steps we should take.

Thanks is advance!

Look in the event log
Look at perfmon on the disk counters for disk reads and writes/sec
How much RAM
Got enough DCs
How many disks
What config are the disks?

"My car is broken, what is wrong with it?" - we need rather more to go on. Detailed tracing in the event log will provide error messages that can be used to help you.
