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...
Second question re. your reply - keeping an exchange server on prem, it's just acting as a management console basically since non of the mail data is stored locally nor does it pass through that server, correct? So I could set up a tiny VM with just Exchange whatever version installed and not have to worry about space for the data, nor CALs since the client licenses are now O365?
After migration you could. Check out hybrid license thou cause the server still needs a license. It’s free, if you already have an exchange license thou you can still use that but eventually you’ll want to change. But your right no cals needed if moved to cloud and used for management only. Just server license being what you had or new server with hybrid.
