Outlook: message to distribution list stuck in outbox

[Leighton]

Hi,

Currently my work place is experiencing problems sending
messages to distribution lists. A message can be sent to
an individual contact, or even multiple contacts entered
manually, but when a message is sent to a distribution
list contact it sits in the outbox and remains un-sent.
We have currently been upgrading PC's around the office
from Outlook 2000 to Outlook 2003. Our server is running
Microsoft Exchange Server 5.5, and our email accounts are
set to 'microsoft exchange server'. Should you require
more information to help me out please don't hesitate to
ask.

Thanks in advance,

Leighton.

Me again,

Thought I'd answer my own post should anyone else have
this apparent problem at some stage. I applied the
Service Pack 4 to our exchange server (5.5) and it
appears to have rectified our Distribution list problem.
SP4 does appear to have been applied at some earlier
stage, so maybe just refreshing the distribution lists
(remove then add again) would have solved the problem.

regards,

me.
