Outlook Missing in Mail Tab

[regression]

Yesterday I started having problems with GMail (via Google's Exchange servers). I wasn't getting new mail / calendar / contacts and the Outlook icon disappeared from my TF3D mail tab.

I went in this morning and discovered the mail / calendar / contacts were unchecked in the ActiveSync setup. So I rechecked them and everything is syncing again. However, Outlook still isn't showing up on the mail tab. I have tried soft resetting and turning TF3D off and on again. I am using the stock ROM.

Any suggestions on how to get Outlook to show up again on the mail tab?

Thanks.
