Support for shared mailboxes
Office 365 shared mailboxes are very useful. Unfortunately, they do not load outlook web add-ins right now: see http://stackoverflow.com/questions/35059067/make-outlook-add-ins-working-with-office-365-shared-mailboxes/35065215
This would be terrific to have add-ins for such mailboxes especially for all CRMs related apps

Hello all! We are happy to announce that the feature was GA on Ignite Nov 8th 2019! Its now part of our 1.8 requirement set!

It looks like this has made it into Requirement Set 1.8
Any update on when we will be able to use it?

I hope the following helps everyone else who's expecting this feature (just like us):
I am not a Microsoft employee, but as per the latest community call (Sep 11, 2019) this seems to be in Preview. It will be released as part of 1.8 or 1.9 of the Outlook JS API (which is either November or early 2020 according to their expectations).
The above is based on the presentation given during the said community call.

Hi
I have updated outlook to 1904 version and tested in May 2019 shared calendar add-in is working. It suddently stopped working in the month of June. Does this feature removed from preview ? How do i find out about this feature being removed or for troubleshooting any information exists ?
Thanks

Hi, is there any update on when this will be available in targeted release/general availability? Also, is joining the Office insider program a requirement for testing this feature? the documentation only says "may have to join".

Is there already a targeted release date for this feature? We've been using it since April in the Insider version of Outlook and would love to use our add-in productive.

This would be a big relief for my daily work flow. I manage multiple inboxes and rely on using trello and wunderlist boards to add emails as todos. Right now I have to log in with a different computer to use the plug-ins and add them to trello/wunderlist.

This is definitely a must for add-ins like Phish Alert or Junk Email Reporting.

Our company has an App (CloudExtend Outlook for NetSuite) and our customers are asking about this daily.

Did anyone manage to read the current email in a shared mailbox (JS: office.context.mailbox.item) with the SupportsSharedFolders set to true or is it still not possible?

This issue is crippling add-ins that help with team-based workflows that use a shared mailbox. How am I supposed to use a shared mailibox for client's requests with one of the workflow-oriented add-ons? Come one, please!!

RAsta commented
Definitely a must since add-ins are extremely useful to solve enterprise problems like workload etc. But without being able for shared mailboxes this isn't useful for most cases.
An update would be very much appreciated. -

The ability for an outlook add-in to work with shared mailboxes would be something we would use all the time as we rely upon shared mailboxes and apps a great deal, but there are problems using them both together.

This is vital in order for the shared boxes to be usable. As of now it is half baked.

Outlook add-ins are working for shared mailboxes in Outlook 2016 for Mac.

Please implement support for shared mailboxes. Lack of this feature is crippling Salesforce's Outlook add-in.

Hi Office Extensibility Team,
Please provide an update on when this will be reviewed and possibly implemented.
To some of the earlier comments, what's the point of user voice if the #1 request is ignored for years with no update?
Regards,
Simon.
