I have 2 laptops with W10 and 2 Lumia 650 Windows Phones. Both laptops run Mail version 17.9330.20915.0 outlook 365 and outlook.com. Both Lumia 650 run Mail version 17.9330.20916.0. At this moment I have Calender and Contacts synchronized between Mail and outlook.com. However I don’t know how to synchronize this arrangement to include outlook365′ own calender and contacts. This is not a question of how to synchronize incoming mail, this works fine, but it is how to make outlook 365 Calender and Contacts synchronize with the existing arrangement. Shall it be possible if I install Akruto?
