I have my own hosting server for basic email and websites with around 10 - 20 customers, I control the dns etc.. and have there sites on my server. I have sucessfully hosted my company email with just my MX records pointing at office 365, but i have a couple of customers that require exchange features the same as me, can i host there emails under my subscription so i can easily manage it or is it better on a seperate subscription? it is purly email hosting required (Exchange Online Plan 1)
Many thanks for your help
