Outlook Client for Mac: Resources added through the Bookings Add-in is not responding

The Microsoft Outlook Add-in Engineering team has fixed the issue with the Outlook add-ins and the release should be available in build number 16.65.825.0 (16.65.22082501) or later.

Depending on the release channel of your organization, it will influence when this updated build is made available.
We will continue to monitor the issue, as the updates are rolled out.

Despite two updates from Microsoft, both versions of Outlook (16.63 and 16.64) are still experiencing this issue with the Bookings Add-in on the Mac client.
Microsoft is continuing to investigate this issue, and we are still awaiting progress on the issue we have raised with them.

We have identified, that the issue is introduced with the newest version of Mac Outlook Client version 16.62. Versions below 16.62 still work as intended.

We have no options for mitigating this in our own Outlook Add-in and Microsoft has acknowledged the issue and put it in their backlog. See: https://github.com/OfficeDev/office-js/issues/2677/
Microsoft has not provided a timeline for a resolution but we will keep you updated on progress.

Current workarounds include:
- Postpone updating to Mac Outlook client version 16.62
- Use the Outlook Web Application
- Switch to the old Outlook Client for Mac temporarily. In the client, this is done by navigating to the top left corner and clicking on "Outlook", and then removing the tick from "New Outlook".
