We apologize for the inconvenience. We currently don’t support the ability to open shared mailboxes or other mailboxes that you have permissions to access.
To open these mailboxes, you can access Outlook from a desktop browser (by requesting the desktop site in the browser settings) or use the Outlook mobile app that can be downloaded from the iOS and Android app store.

Not long ago I still could see my shared mailbox from my mobile from the browser, not anymore now.
This point myself I also raised 1 year ago and at that time there where already many inquiries about this. When can this function be facilitated, it’s part of outlook and my mailbox, now due the inability to access it not provides me the high end product and efficiency I am expecting from Microsoft!!
Access to shared folders it’s a must have for many, please sort it out!!
