Outlook 2000 auto check mail?

Hello there,

I have 2 PC’s that RAS dials into a Exchange 5.5
I can’t find the auto receive mail, so I can set a time to dial every say 15 mins to collect mail.
I have a dial up connection set. This is just that the staff sometimes don’t bother checking their mail and to try to make it easier for them.

I am pretty sure I have seen it in previous versions of Outlook. I have researching on the net but only auto receive feature is in the internet mail service on LAN connection. So I am just wondering if this is possible with Outlook 2000.

I hope this makes sense
Any suggestions would be greatly appreciated.

Regards
CJ
