We have a hybrid AAD/EXO environment, with all user mailboxes migrated to EXO - but still many on-prem app dependencies & synchronization is configured using AAD Connect.
We have a range of on-prem AD accounts that are being synchronized to AAD; and in Teams these on-prem accounts how up as an option when managing Team memberships, even though the synced on-prem accounts **are not** mail-enabled.
THE QUESTION: is it expected that NON-mail-enabled accounts can be discovered/added to a Microsoft Team as a members?
In this screenshot below, the 2nd listing is a standard on-prem account - without email/messaging - that's synced to AAD via AD Connect... doesn't seem like it should even be an option to add to a Team since the account doesn't have an email address:

Yes, it is expected that non-mail-enabled accounts can be discovered and added as members to a Microsoft Team. This is because Teams uses the Azure Active Directory (AAD) global address list (GAL) to discover users and groups. The GAL includes all users and groups in AAD, regardless of whether they are mail-enabled or not.
When you add a non-mail-enabled user to a Team, they will be able to use all of the features of Teams, including chat, meetings, and calling. However, they will not be able to receive or send emails from within Teams.
In the screenshot you provided, the second listing is a standard on-prem account that is synced to AAD via AD Connect. This account is not mail-enabled, but it is still listed in the GAL because it is a user in AAD. As a result, it can be added as a member to a Team.
It is important to note that there are some limitations to using non-mail-enabled accounts in Teams. For example, non-mail-enabled users cannot use the following features:
Overall, it is possible to add non-mail-enabled accounts to Teams, but there are some limitations to keep in mind. If you need to add a non-mail-enabled user to a Team, you should weigh the benefits and drawbacks before doing so.
