Hi @xiffus1987 ,
PowerShell said this, but I miss "Exchange Server 2016 Basic CAL" there.
According to this official link, the Get-ExchangeServerAccessLicense cmdlet returns a collection of these license names:
- Exchange Server Standard CAL
- Exchange Server Enterprise CAL
- Exchange Server Standard Edition
- Exchange Server Enterprise Edition
So per my understanding, it's expected that the Basic SAL is not included in the results returned.
Then when it comes to the question you asked, would you please elaborate it a bit more so that we can understand better about the situation? From your description, are you currently using the Basic SAL in your environment and are trying to configure the OWA features? What exactly you wanted to configure and what you mean by "All functions except Outlook on the web"? More additional information would be appreciated.
Furthermore, considering that the the issue sounds relevant to the licensing, personally I'd recommend also contacting Microsoft licensing support as they would be more familiar with license related questions and might provide more information about this.
