Email rules for shared mail box

We recently introduced a shared mailbox to our office365. I added an alias called flaschenpost@newcubator.com to it, to receive all their mails including the invoices. Now I needed a rule to forward the invoices to our invoice@newcubator.com mailbox. Creating a rule for the shared mailbox is easy when you know where to look! In short: you have to open the shared mailbox in a separate browser tab and then create the rule under the settings menu as normal. To open the mailbox in a separate tab click on your profile icon and then on open new mailbox / Weiteres Postfach öffnen. Enter the name of the mailbox and voila! Now you can create rules for that mailbox.
