My suggestion is to completely move over to Office 365 and use ADFS for SSO. Hybrids are not easy to maintain and much more expensive. As &nbsp;you are paying both On-prem and cloud license fee.

I currently have a hybrid exchange environment, office 365 tenant using ADConnect to sync all identities. &nbsp;<br />
<br />
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.<br />
<br />
Is this as simple as creating an account, and assigning a license? &nbsp;Which will then in turn create the mailbox? &nbsp;Or do attributes have to be accounted for and is there a better process for this?<br />
