Hotmail email with business 365 subscription

Vince Viking 21 Reputation points

Is it possible to use an existing email address with a business 365 subscription so that I can utilize the increased sent email attachment limits etc and if so, how would I go about doing this? Would I still login to hotmail in the same way? (

    Exchange online and Hotmail are two different products. You can not use Office 365 subscription to improve the functionality of your mailbox, it will create a new mailbox for you.

    Based on my searching, you could buy outlook-personal-email-plans to expand your Outlook/Hotmail mailbox. But, I'm not sure if it can expand the allowed attachment size, you could confirm from the forum. The forum is support for Exchange related question.
