Outlook getSelectedItemsAsync does not populate conversationId in results

[maoueh]

In issue #4960 (comment), it was suggested to use Office.context.mailbox.addHandlerAsync(Office.EventType.SelectedItemsChanged, () => { ... }) and getSelectedItemsAsync to overcome the fact that ItemChanged is fired only for a pinned taskpane.

However, the getSelectedItemsAsync seems to be bogus by not populating the conversationId field of the selected items.

Your Environment

• Platform: Mac
• Host: Outlook
• Office version number: 16.89.3 (24092813)
• Operating System: macOS

Expected behavior

With an Outlook extension that defines a taskpane which has multi-select APIs enabled, use the following code:

  Office.onReady(() => {
    console.log('Init after Office Ready', Office.context.mailbox.diagnostics.hostName)

    Office.context.mailbox.addHandlerAsync(Office.EventType.SelectedItemsChanged, () => {
      console.log('[Outlook] SelectedItemsChanged event')
      Office.context.mailbox.getSelectedItemsAsync(result => {
        if (result.error) {
          console.error('Error getting selected items', result.error)
          return
        }

        console.log('[Outlook] SelectedItemsChanged result count', result.value.length)
        result.value.forEach(item => {
          console.log(`[Outlook] - Item ${item.itemId} - Conversation ID ${item.conversationId}`)
        })
      })
    })
  })

When the selection changed, you will see the following logs:

[Log] Init after Office Ready – "Outlook" (index.tsx, line 22)
[Log] [Outlook] SelectedItemsChanged event (index.tsx, line 24)
[Log] [Outlook] SelectedItemsChanged result count – 1 (index.tsx, line 30)
[Log] [Outlook] - Item AAMkA...QQKOAAA= - Conversation ID undefined (index.tsx, line 32)
[Log] [Outlook] SelectedItemsChanged event (index.tsx, line 24)
[Log] [Outlook] SelectedItemsChanged result count – 1 (index.tsx, line 30)
[Log] [Outlook] - Item AAMkA...QS4FAAA= - Conversation ID undefined (index.tsx, line 32)
[Log] [Outlook] SelectedItemsChanged result count – 2 (index.tsx, line 30)
[Log] [Outlook] - Item AAMkA...QQKNAAA= - Conversation ID undefined (index.tsx, line 32)
[Log] [Outlook] - Item AAMkA...QS4EAAA= - Conversation ID undefined (index.tsx, line 32)

Current behavior

The conversationId is undefined always when receiving the results back from the getSelectedItemsAsync.

It should be populated.

Steps to reproduce

1. Implement an Outlook Add-In with a taskpane and multi-select permissions.
2. Use the code provided above
3. Select messages in the inbox
4. Inspect the printed logs and observe that conversationId is undefined.

Provide additional details

It appears this could be a bug with the Outlook native client only (maybe just on OSX too). Indeed, I've performed the same test using Outlook for Web and there, the conversationId field is properly populated.

Context

Trying to overcome the limitation that ItemChanged which is emitted only for pinned taskpane even though our taskpane even when not pinned is still visible and as such, doesn't react to user changing messages.

We worked around the current issue by using itemId and retrieving the message in question and finding its conversationId. This is incurring extra calls in the backend as the itemId here is a mutable ID so we need in the backend to first convert to immutable ID (which we store internally for messages) via a Graph API call to TranslateExchangeIds to make the mutable itemId immutable and perform the lookup correctly.

Useful logs

See logs above, see following screenshots which is my test session.

@maoueh
Just to confirm, are you saying that it works as expected on Outlook Web, but not on Mac?

[maoueh]

@neprasad-microsoft Correct.

[maoueh]

When I say Mac, just to be clear I'm talking about the native Outlook Mac app

[maoueh]

I hadn't the chance to test native Outlook Windows app yet.

Hi @maoueh
My apologies for the confusion. 'conversationId' is a part of API set 1.14 which is not yet supported on Mac. This is in our Feature backlog, but unfortunately, we do not have any timeline for this. Thanks for your patience.
