Items not Sync'ing for one user.

Hi

I have a support team that shares 3 mailboxes. Everything works fine for all
users except one.

UserA can sync and view up-to-date mailboxes / tasks for 2 of the 3 group
mailboxes. The team uses the TASK TO field to assign emails to members of the
team. When someone tasks UserA an email it does not show on his Outlook
client, but does show for everyone. This is only the case with one of the
group mailboxes. Works fine with the other two mailboxes.

We have tried removing and adding the mailbox - recreating the user profile
- logging onto a different machine. WinXP - Office 2003 SP3.
Permission have been set according to the group which the all the member
belong to.

Any ideas?

Thanks
