I'm using Outlook 2010 at work (Exchange). My account is also synced to my Android phone+tablet. For me there is no other solution than to able to add this new calendar to my Outlook, so that I'm able to see all of my calendars side by side, etc...
My spouse uses Hotmail (Outlook/Live or whatever it is these days). She uses this account with her Windows 8 laptop, iPhone and iPad. She's also able to use Google Calendar if that would make this work...
Is there a way for us to have one calendar that we would both be able to edit on all of our devices?
I've done some googling for the better half of the day without any success - I'm starting to think that this is not even possible...
