If you are getting the error "insufficient memory unable to load font when openning word" when you try to open a word file or new email message in out look following steps will able to fix it for your.
1. Restart the Computer. In my case it worked and restart fix lots of computer related problems.
2. Try to boot up in safe mode. If the error is not coming up then most probably one of the Addons will be causing the problem. Try to isolate the Adon that gives the problem and uninstall it or install the latest update might fix the problem.
3. Corrupted Font or Printer Driver files may cause the problem as well.
