Are these messages it didn't work on also Plain Text?
Let's take one of these and try changing it to HTML or Rich Text, and then
change it back to Plain Text. In the Office Ribbon, select Other Actions |
Edit Message. Now, select the Options tab above the Ribbon. Select something
different (select Continue if you get a warning box). Save it, then repeat
to go back to Plain Text.
I can reproduce this, but it's affecting all Plain Text messages when I do
it.
Again, I can't imagine the Windows display settings are at play here because
it's not affecting all messages, but it may be worth checking:
I'm not sure which OS you're using. In Control Panel...
Windows Vista - Select Personalization | Window Color and Appearance | Open
classic appearance properties for more color options | Advanced...
Windows XP - Open Display | Appearance | Advanced
Check the colors set for Window Text (select Window from the Item
drop-down). What is set for Color 1 (Window background) and Color (Window
font)?
At this point, it may be worth attempting a repair on the MS Office
installation from Control Panel | Add/Remove Programs or Control Panel |
Programs and Features (Vista).
