I still try to use my Hackintosh as much possible, though it's not quite as much as I like. Because I use it reasonably often, I now like to keep up to date with things like Office 2011 for Mac updates from Microsoft.
I saw just the other day that there is a new update. See this link:
It takes Office to version 14.3.7, and the file is 113 MB. I have downloaded it and installed it, but, as my production mailbox isn't touched by Enterprise Vault I can't tell you whether it works still with the Enterprise Vault Mac Add-in. So remember to give it a try yourself in a lab environment before the update for Office is pushed out to users.
