Q: Where have my MS icons gone in Yosemite?

Same for me here... clean install of the latest yosemite on a brand new macbook pro ; the problem appears with various apps (not only MS) and is probably related to yosemite only... ; tried everything mentioned here without success. Hope this will be fixed soon...

Same here , tried everything, nothing has any effect.  Yosemite is sooo slow !!  So much I hate about it. !!  Simple things like having the spotlight window in the middle of the page. :lol: 

Indeed TinkerToolSystem 4 did the trick, and whatever the app for which you have icon problems (it restored icons for MS, torrent files, inc files, php, sitx, etc...) ! I bought it yesterday .

I wonder how the cache cleaning option of this app works because I have tried everything for manually cleaning os x caches without success...

To restore program icons (e.g., MS office, pdf, etc)

In Yosemite -> Open Finder -> Right click a document file -> select Show View Options -> Uncheck Show Icon preview

Hope this helps.

This solved it for me with exact same issues as others here.  Deleting /Library/Caches/com.apple.iconservices.store does the job. You will need to enter your administrator password for this. Follow up with a reboot.

1. Delete the contents (including hidden files) of the following Cache folders:
   1. /Library/Caches
   2. /System/Library/Caches
   3. /Users/{YOUR_USERNAME}/Library/Caches
2. Reboot

This worked for me.

Bought new MBP with Yosemite pre-installed a few weeks ago and had the same issue since I installed MS Office.

Deleted all files in all 3 folders as you recommended. (Just into trash) and restarted.

Problem solved, thanks!

I was trying everything without sucess ad finally Onyx worked for me. IMPORTANT: Make sure you check 'Icon services' in the User tab under Cleaning section, by default it is not checked and I think that is what solves the issue

Tried everything for weeks -- this finally worked for me! Thanks guimarca!

I tried everything from clearing/ resetting caches manually or with Terminal to cleaning the harddisk using Onyx and other programs. Nothing helped until I did the following: completely remove and then re-install Microsoft Office. I don't know whether this will be the solution for everyone here but I guess it's worth the try.  

Fix that worked for me but not for a friend of mine ...

Right-click the document icon > Show View Options

De-select "Show icon preview"

Never mind this ... do what JK9 suggests above (deleting the iconservices folder)

I don't think you need to go this far.  JK9 suggests deletion of a single folder/file within the Library > Cache folder, and this seems to have worked perfectly for me.

This provided the solution for me:

I lost the whole desktop (except for one icon) in front of a class today after plugging an HDMI cable in, via a Moshi adapter.

I'm using a MacBook Pro 17 Mid-2011 with the latest Yosemite. I was running a 1920X1200 screen on a 1920X1080 projector

After resetting the PRAM, deleting some plists and making a few other stabs in the dark, I clicked on my desktop, which revealed the "Finder/File/Edit/View/Go/Window/Help" tabs, then I chose "View>Show View Options." I slid the "Icon Size" to the tiniest possible size, then I slid the "Grid Spacing" to the largest possible size and did a "Command+A to select all. I dragged my one Icon to the left and voila! Icons! All of those rascals were hiding just off the right side of my screen. I guess there's more than 1920, virtually speaking.

I Have this issue come and go not just for ms files but ALL file Icons. Then some reappear but many files are "missing" the icon even though the are there. I have done several Disk verify and permission verify..because of slowness. If this is a Yosemite bug why has is not been fixed?
