??? Missing Mail Icon on TF3D Mail Tab

[TrudgingCitizen]

HTC Touch Pro from US Cellular
Using default TF3D
Slide over to the Mail tab
On the right hand side of the screen, I have a "create new email" icon and two envelopes that represent two different email accounts. However, I have three email accounts configured (two POP3 and one Outlook/GroupWise Mobile Server). Only the two POP3s are showing.

The GroupWise Mobile Server program pushes email to the Touch Pro's Outlook folder, updates contacts and calendar items as well. This is all working perfectly. The only thing not working is the icon for this email account isn't showing up on the main Mail tab.

... and since it's not an option on this tab, I can't select my GroupWise account and use the "create new email" icon or quickly scroll through the emails that show up as a big picture on the Mail tab.

Thanks in advance for any ideas on where I can start.

Thanks to the information in this forum, I learned how to do a screen print from my device. It's attached. It shows the screen that I'm asking a question about.
