Hello Ornelam

PLease have the AAD Connect installed first to have hybrid identities.
After that I would not bother with an on-premises messaging server anymore but go for M365, probably E3 license, for each user. All your configuration happens in the Office portal and the clients Outlook can be directed to get the mails directly from Exchange online. Saved my a lot of work and trouble.

I hope that helps.

Cheers
Rolf

  Hello Ornelam
  May this can help you:
  https://docs.microsoft.com/en-us/exchange/mailbox-migration/migrating-imap-mailboxes/migrating-imap-mailboxes
  And you do not need an Exchange server for the management. All is done in portal.office.com
  I hope that helps
  Cheers

Thank you. I want to migrate the existing mails, and to do that i should have all my users in the cloud, and i should give them an exchange licence. If i run ADconnect first, how can i be sure that than the exchange server that i want to install for management (i dont want to manage my user mail attributes with Powershell or ADSIEdit) will than know that the users have all their mail in Office 365?
