We have purchased a handful of licenses for Office 365 E3 for a long term test / playground. To make the login look better we have added our production domain, so we can login as: MyName@mycompany.com but now that we're thinking about it, our real email addresses are in the same format MyName@mycompany.com ...I imagine we do not want to use our production domain for 365... since we will want to play with the online email too. Seems like an issue could arise if Office 365 and our production email have the same address. Can someone verify what we should do? (probably use a different domain for 365 than production...)
Thanks for your time
