    More months have passed and this is still broken.

    It seems Microsoft cannot even support their own stuff properly.

    Too bad, i was looking forward to this

    I'm struggling to understand Microsoft's logic in releasing a major service that isn't functional and ignoring this specific issue for months.

    Our organization is now rolling out Co-Pilot, which shockingly requires the use of 'New' Outlook. How do they expect enterprise organizations to operate? This is a messy, frustrating roll out.

    The issue is not with the Calendar, it is with accessing the Shared Mailbox for the account. While I can add the calendar without any errors, this does not make the mailbox work.

    I am the administrator and I have given myself full read and manage permissions to the Shared Mailbox. Permissions is not the cause of this issue, rather a broken feature in the app.

    Hello All,

    Make sure your administrators have given you read and manage permissions for that specific Shared Mailbox
    Now, if a new calendar has been created by Shared mailbox you should be able to add calendar manually.
    Make sure the calendar you are trying to access has been shared with you.

    First click Add Calendar, then select Edit my calendar OR use Add from Directory.
    Type the name of external or shared mailbox email address and it should let you select it and add to list.

    I have finally been given a solution to this issue, after many, many back-and-forths with Microsoft. Not sure why they wouldn't release this information to admins when they started pushing New Outlook, but I'm at least glad to have finally found a working answer.

    Essentially, you need to follow the steps in this article.

    Troubleshoot shared mailboxes in new Outlook - Deploy Office | Microsoft Learn

    You will be setting the mailbox policy to true with the following attribute:

    -OneWinNativeOutlookEnabled $true

    I opted to use the second option, 'Custom OWA Mailbox policy' so I could test before pushing this policy to all mailboxes in our organization.

    I did eventually set the Default as well, and have not noticed any unexpected changes to the applied mailboxes.

    Hopefully others following along can apply this and finally have this issue behind them!

    When using Outlook in web browser I noticed I could add a shared folder and it showed up under my main inbox as expected. Seeing as there is no visual difference that I can see in new Outlook vs Web Outlook. I decided to just install Web Outlook as web app on my desktop (How to install website as an app).

    I have now used this for over two months and have only had issues when having to open .eml files I have to open in classic Outlook. But last I tried this in New Outlook it didn't work there either.
