A common enough occurrence with Office. But no, you do not need to reinstall all. Just need to visit FontBook's Edit menu, do a Look for Enabled Duplicates... and for each family that pops up as duplicated, do a Control-Click on its name and do a Resolve Duplicates.
Purging all MS fonts will only get you further grief when you try to use any of Office's apps and/or receive documents from other Office users.
FWIW, my font collection that dates back from 1993 when I got my first PowerBook, carries 344 fonts including all from about 5 Office iterations. All work, none are corrupted and there are no duplicates.
I do need to reinstall all of them
I did a look for duplicates and it was a 99% of them had duplicates, the entire office for Mac fonts were placed into the font book
I don't have office for Mac on here any more (had a school agreement licence), and the dupliacte fonts were causing my apps to crash
A office for mac update placed the fonts in there, I am still geting font errors in the console messages
Ok, if you insist...
On the left "Collections" column you should see a Microsoft collection. Control-click on it and knock yourself out. You may also want to do a Restore Standard Fonts..., in the File menu, afterwards just in case you got too eager and blasted any of the all-important system fonts.
Office didn't actually add anything to Font Book itself. It added a bunch of fonts to the /Library/Fonts/ folder. Font Book saw them and added the fonts to its list.
First, close Font Book.
Office created a folder named FontsDisabled in the /Library/ folder. You can delete that folder entirely. It also adds a bunch of older legacy TrueType fonts which conflict with the newer OpenType fonts. In the /Library/Microsoft/ folder, delete the following fonts. Note that they do not have a file extension.
Arial Rounded Bold
Comic Sans MS
Launch Font Book. The conflicts should be resolved.
They all were vaild, and I don;t know which ones I have in the fontbook Apple OS X ones or Microsoft Offices ones
I have 158 fonts right now w/ OS X 10.7.4, can anyone else check and see what it should be, and how Do I reinstall the OS X ones?
Here is one of the font errors
Opera: ATS: Invalid FontObjectID (234) - only low 16 bits are being passed in.
When I had all the dupliactes Opera and others were crashing
