I originally bought an O365 Business Premium subscription because I wanted email, invoicing and customer management. I found that the later two are only available to subscribers in the United States.
I have paid three times the cost for almost no value. I would now like to switch from my premium subscription to a home subscription. My question is, can I switch from exchange to outlook online? Will I be able to keep existing emails? Will I be able to use my custom domain for email? If I switch over, will I be able to keep my files in OneDrive without first downloading them then re-uploading them? I notice that OneDrive for business has a SharePoint url unlike OneDrive for consumers.
