Using Word/Outlook 2010 on Windows 7 Enterprise.

This behavior started out of the blue recently.

Each time I start a new sentence in Word or Outlook and if the new sentence starts with the word The, Outlook or Word autocorrects it to use lowercase.

I've checked the autocorrect settings:

Outlook: File > Options > Mail > Spelling and Autocorrect > Autocorrect Options
Word: File > Options > Proofing > AutoCorrect

...but I cannot find any entry that would produce this result.

I've tried adding a new entry:

replace . the with . The
...but that doesn't work either.

I've checked the beginning of each AutoCorrect list to make sure that there isn't an entry in the symbols section. No luck.

Any ideas?
