Delays in sending emails....

Good Morning ~

I have a strange problem with only a few of my Outlook
clients. It seems that our emails do not get sent out,
whether they are internal or external, unless we close
out of Outlook and reopen the client. I tried repairing
MS Office, I deleted my profile and reconfigured it, but
neither of these things helped. I really don't think
it's my Exchange Server, because there are no emails
waiting in the queue.

We are using Outlook 2000, and the majority of the people
having this problem do have offline folders setup.

Any hints on why this could be happening?

Thanks in advance,

Sunnie
