Ok here is the situation...
All of our workstations have Office XP loaded on them, and our employees are using Outlook Exchange XP. We have some Execs that have laptops that are running Office 2007 and Outlook 2007. Now these people on laptops are set up to POP into our Exchange server, while all our desktops are directly connected to our Exchange 2007 Server.
When ever one of the users tries to reply to one of the Execs on POP, their Outlook errors out and Shuts down.
If the Exec sends the email via the web using OWA, then no one has a problem repling to them, it is only when they send an email when they are POPed in.
Exchange 2007 standard
Workstations loaded Windows XP and Office XP
Laptop's Loaded Windows XP, Offive 2007
Does this make since to anyone out there? Need more information, just email me!!
