I'm interested to hear you've had a good run with O365 - or organisation (100 people) have been using it for 3 years and it's a nightmare, weekly outages, very poor performance, browser compatibility problems with anything that's not IE, missing emails and to top it off absolutely shocking support.
Ouch, that does not sound good. I don't use their email service. I signed up to get the 1 terrabyte of OneDrive storage per member of my household, and almost as an afterthought then started using OneNote, Word, and Excel.
