Hi, I'm migrating about 50 users from G Suite to Office 365 Business email. Moving accounts and inboxes also as a one batch go.
Users are already set up in Office, with their default @company.onmicrosoft.com email. Gmail currently uses their own domain as @company.co.uk.
Haven't registered the company.co.uk domain with Office 365 Business yet.
I'm wondering if, as soon as I register the domain and start migrating the users, will they lose access to their @company.co.uk gmail, as Outlook will take over the domain or will they have access on both Gmail and Outlook? I'm only worried, since it's an own domain email.
Summed up: firstname.lastname@example.org is using gmail. I want that email to be in outlook, but afraid, that as Office acquires the company.co.uk domain, and able to use it's email addresses Gmail will lose access. Hope that makes sense.
