I hope this is the correct forum!

I have a Windows 10 PC and a Windows 8.1 mobile phone.
I use Office 365 (Home) and Skype. (installed on both devices)

I also use Akruto Sync to sync contacts, tasks, calendar items between the two devices.
I am using Akruto because my understanding is that Office 365 (Home) only supports Exchange for email. I need Office 365 (Home) because I use the Access database.

I am getting duplicate contacts on each device. If a person is both a Skype and Outlook contact, that person will appear as two contacts in my Outlook address book.
I also seem to have contacts in both my Akruto account and my Office 365 account.

So it is a mess!

Do I still need to use Akruto sync?
What is the simplest method to keep contacts, tasks, calendar items in sync between the two devices?

Thanks in advance
