Hi Vic,
Contacts and tasks can be transferred from your Outlook to the Office 365 account by exporting and importing data. Please take the following steps:
1. Export Contact from Outlook 2010
3. Export Outlook items to an Outlook Data File (.pst)
4. Connect Office 365 account to Outlook
5. Import Outlook items from an Outlook Data File (.pst)
Thanks,
Keats Ge
