How to Fix “Share to Outlook” Not Working in Teams

Enable Outlook on the Web

Additionally, you need to enable Outlook on the Web. Otherwise, the “Share to Outlook” feature won’t be available. When you click on More options, there will be no “Share to Outlook” option displayed.

The quickest way to turn on OWA is to run this PowerShell command: Set-CASMailbox -Identity “UserName” -OWAEnabled $true.

Alternatively, you can use the new Exchange Admin Center (EAC) to turn on Outlook on the Web.
