Missing web add-ins from ribbon in shared mailboxes on Outlook Online, but still having the event-based part functioning. about office-js

Hey @bogdanst24

Can you please share the network logs over to: [email protected] for further investigation?

[bogdanst24]

Thank you, shared the network logs

The mail we received from you is for a different issue.
Please collect the logs for the issue #4045 and send it over to [email protected].

Also, please use the Issue No - Issue Title as the subject.

I have reshared the logs through a link now, as the attachment might have been too big for our policies. The network logs are for the correct issue and reproducing it.

[bogdanst24]

Were any changes made? I can't see the issue anymore, meaning that the web add-ins are not functioning at all in the shared mailbox now (when opened as another mailbox).

The store is completely empty, the legacy in-client store doesn't allow installing any add-in, and deployment through the admin center targeting the shared mailbox doesn't do anything.

You should be able to install add-ins via legacy store using the URL : https://aka.ms/olksideload.

I am aware of this hack and am using https://outlook.office.com/mail/inclientstore instead as that is accessible even on shared mailboxes. However, it looks like addins cannot be side-loaded in shared mailboxes.

I just found this list of requirements for a web add-in to work in shared mailboxes, but something is not right.

What we have currently (deployed and used by customers:
Manifest with ReadWriteItem permissions, no SupportsSharedFolders set, and event-based behavior alongside the task pane.

Current behavior
The web add-in is not visible in the shared mailbox as a deployed web add-in and cannot be accessed. However, the event-based is still working just like I reported it initially with no option to open the task pane. The task pane part is expected.

Questions and issues

1. In this scenario, on shared mailbox opened in a new tab and a manifest without SupportSharedFolders set, Is it supposed to run at all if the requirements described in the documentation are valid? The fact that the event-based part is still running looks like a bug.
2. Is this entire list of requirements correct for a web add-in to run in shared mailboxes opened in a new tab? Grabbing requirements from different articles:

• SupportsSharedFolders set to true in the manifest, just after the DesktopFormFactor, with both VersionOverrides registered
• The Web add-in has to be deployed centrally. Does not work when sideloaded.
• The Web add-in is deployed to both the user and the shared mailbox. It is not enough to have it deployed to the user only.

Is this still an issue or does #4110 clarify your questions?

[bogdanst24]

Yes, this is still an issue

Hi @bogdanst24 - Which specific point is the list is still an issue?

[bogdanst24]

It is the main point of this report. Web add-in deployed only to the user (not deployed to the shared mailbox), with:

• event-based activation on "OnNewMessageCompose"
• no SupportsSharedFolders set

Current behavior: the web add-in is not visible in the ribbon, but the event-based action is triggered.
