Yes people, this really does work (and very well).
1. Install the latest wine from the community repo.
sudo zypper ar http://download.opensuse.org/repositories/Emulators:/Wine/openSUSE_13.1/ wine
sudo zypper ref
sudo zypper dup -r wine
sudo zypper in wine samba-winbind
2. Install office
WINEARCH=win32 WINEPREFIX=~/.office wine /setup/directory/setup.exe
3. The office apps should now be in your menu, if not… (change OUTLOOK.EXE for whatever you’re opening)
WINEARCH=win32 WINEPREFIX=~/.office wine ~/.office/drive_c/Program Files/Microsoft Office/Office14/OUTLOOK.EXE &
4. Add a library override for riched20:
WINEARCH=win32 WINEPREFIX=~/.office winecfg
Go to the Libraries tab, type “riched20” in the “New override for library” box, then click Add, then Apply.
If you need to configure Outlook:
First open Outlook, and tell it to NOT configure mail at this time (configuring mail within Outlook appears to be broken).
WINEARCH=win32 WINEPREFIX=~/.office wine control
Click on Mail. The rest is the same as if you were configuring on Windows.
Here are some more specifics for actually installing Office: http://appdb.winehq.org/objectManager.php?sClass=version&iId=17336
Only the 32-bit installer works. I happen to be using MS Office 2010 Professional Plus.
