I have an O365 account I use only for contacts and calendar. This account is installed on my outlook 2010 win 7 machine, my iphone and my wife's iphone.
My phone and outlook work fine - add a contact or calendar event in 1, it shows up in the other OK.
but my wifes doesn't seem reliable - she adds things and it most often doesn't show up in my outlook / phone. And things I add now don't always show up on her phone.
any advice? I was thinking I could delete the account on her phone and recreate it... but want to know if there's some troubleshooting I can do otherwise
