Hello Adam Peck
I am following up to confirm if you were able to successfully provision the new email account for your employee. As a summary, this process is handled entirely within the Microsoft 365 Admin Center at admin.microsoft.com under Users > Active users. The most critical step in the Add a user wizard is ensuring a license containing the Exchange Online service plan (such as Microsoft 365 Business Basic or Standard) is checked; without this specific license assignment, the account functions only as an Azure Active Directory identity and will not have a mailbox allocated to receive mail. If you see the user created but they cannot access Outlook, please verify the license assignment status in the user's properties.
If the issue has been successfully resolved, please consider accepting the answer as it helps other people sharing the same question benefit too. Thank you!
