My Entourage 08 Calendars would not print. I have a iMac 24 running OS 10.4.11 with Office X and recently Office:Mac 2008 and the possibility of some older pieces of Office prior of OS X.
The problem is a conflict between some old pieces of Office X and the new Entourage 08 in your own account.
A crude but effective fix I found follows:
* ******Only make these changes within your own account or another corrupted account.***********
1. Open Entourage and under File/Export/ Archive all of the email, calendar events, etc. you need to preserve to a safe temporary file on your desktop.
2. I also saved my Custom Dictionary from "my account"/ Preferences / Microsoft/ Office 2008 / Custom Dictionary in the safe file.
3. If you still have the same files in an older version of Office X you want to preserve, you may desire to save those the same way.
4. Next go through your account only, and trash all folders and their files that have the name Microsoft, Office, or Entourage in the folder or file name and empty the trash. All of these file you have trashed will be replaced with new empty replacements with all your preference and data gone when you restart later.
Do not delete your document files that you have named and that end in .doc, .docx, .xls, .xlsx, .pps, etc.
Restart your computer and replace the files you saved such as Custom Dictionary and start Entourage and Import the archive file you save earlier, and you should be in good shape again and able to print the calendars.
Good Luck and ask Microsoft why they don't debug their stuff.
