Randomly delayed emails

[Colinest84]

Hello,
I have a client that is used Windows 2003 SBS with outlook 2007. When he sends emails most the time everything goes through fine. At random times he will send an email and it will not show up in the mail box of the recipient for anywhere from an hour to a day. I would think it was an issue with the server but there is another person working with him who sends out as many if not more emails and they always show up in minutes. Any ideas?


Thanks

Hi there,
It could have something to do with the cached settings on the client side...also possible is that the firewall (again on client side) needs MAPI exceptions.
Just a stab in the dark though
