Migrating from Exchange 2019 onPrem to Exchange online - new onboarding process

Question

Hello,

currently we have an Exchange 2019 Server in Hybrid configuration with Exchange Online. During our user onboarding a mailbox for the user is being created by a business rule:

Depending on the department we are running a script to assign a group for licensing a M365 license and setting an AD attribute for a scheduled task which will later on migrate this onprem-user-mailbox to Exchange Online:

Now we are in the process of migrating every user to Exchange Online and decomission our onprem Exchange and replace it with the Exchange Management Tools. Therefor we need to redesign our onboarding process. According to https://www.adaxes.com/help/EnablingDisablingRemoteMailboxes/ Adaxes would automatically create a remote mailbox if a M365 license is assigned. Now we are assigning licenses via group assignments and not via direct assignment. What would be the best practise with Adaxes to create new Remote-Mailboxes in this scenario for newly created AD-Users? Thanks and KR Christian

Hello,

Unfortunately, there is no possibility to achieve that. To be able to enable remote mailboxes via Adaxes, you need to have on-premises Exchange, not just the Exchange Management Tools.

Thank you for the fast response. Is this planned for a future release? Thanks and KR

Hello,

There are no such plans and it is generally not something that is expected to be used. Keeping just the Exchange Management Tools is something you can use during migration, but it does not have all the functionality on an Exchange server. If you do not need on-premises Exchange, you can just decommission it totally and proceed with using only Exchange Online.

THanks again for the reply. How would be the best practise in Adaxes user onbaording without onpremise Exchange and only Exchange online to deploy a mailbox to a user in exchange online? Thanks and KR

Hello,

The only thing you need to do is automate assignment of a Microsoft 365 license with access to Exchange Online. For details, see https://www.adaxes.com/help/AutomaticallyAssignOffice365Licenses.
