Use an Alias in Outlook 2016 for Windows

If you have set up an alias with us, you can also use it on your Windows computer with Outlook 2016.

We do not offer support for Mail clients (as there are simply too many, and we do not develop this software), but we are happy to provide instructions for specific use cases.
First, set up your mailbox main address in Outlook 2016. The mailbox address must be integrated into Outlook before you can use this feature.
