Office 365 Home and business essential
I am starting a small business company. I already have Office 365 Home (2016) subscription and desktop program (Excel, Word, OneNote) downloaded on my desktop. But I need Exchange and am thinking of buying Office business Essential. Are any problem about using these version together on the same desktop?
I recommend checking out this guide from Microsoft on how to upgrade from Office 365 Home to a Business subscription. Rather than purchase Business Essential separately, upgrading should allow you to easily migrate all your data & programs into the new subscription.
