I can certainly go on and on about all that is wonderful about working with both Office 365 and CRM Online every day.
I can mention items such as having access to the complete hierarchy of my accounts and contacts easily accessible on my phone, to not having to wonder if the calendar on my phone, within my CRM system or on my computer has everything that I am suppose to know about, BUT
Screen shots, Videos, Words all wrapped up in one.
Enjoy!
