Hello,
I was wondering about something concerning a transition between a MOSA and an EA.
For example, let's imagine that my company has 1,000 users. We have purchased 1,500 are Exchange Online Plan 1 licences on a MOSA and want to move to Exchange Online Plan 1 on a Enterprise Agreement.
My questions are the following:
1. There will be an overlap in time when the two subscriptions will coexist. My Office 365 portal will show 1,500 * 2 = 3,000 Exchange Online Plan 1 licences. In case no users have been created since, we'd have 3,000 - 1,000 = 2,000 licenses left. If I create a new user, will it be created on the MOSA or on the EA subscription ?
2. How will the transition happen when my MOSA is actually cancelled? Will I need to reassign all the users to the new Exchange Online subscription?
3. Will there be a service interruption?
Thank you in advance for your answers.
