I currently have a hybrid exchange environment, office 365 tenant using ADConnect to sync all identities.
I need to change the mailbox provisioning process (previously was creating an on prem mailbox, setting the primary SIP/UPN/Proxyaddresses) then giving a License and migrating the mailboxes.
Is this as simple as creating an account, and assigning a license? Which will then in turn create the mailbox? Or do attributes have to be accounted for and is there a better process for this?
