Question regarding UPN and AD pass through
Hello and pardon the question if I missed the answer elsewhere. We are finally migrating off on prem to O365. I would like to use pass through authentication but have questions about the UPN, pub...
Now keep in mind that's in regards to Exchange, you still need Windows Server Cal's for users if they still authenticate on-prem in any way.
OK. We are maintaining an on prem AD environment so should have more than enough Windows Server CALs for that purpose.
Thank you
