I have an office 365 account, and I noticed whenever I do a search, none of the keywords are highlighting. I verified the highlight feature is checked in Options>Search>Highlight search terms in results, and still no luck. Not sure what the issue may be. I am on Windows server 2012 with one email address and Yosemite using another, and the feature doesn't work on both platforms. Both are office 365 accounts.
Thanks
