Teams Join Button not showing up

[pabloortega]

Hi all, hopefully someone has experienced this issue before.

When creating a Teams meeting invite and inviting a Cisco Room Navigator + Room Kit room, the join button fails to appear on the panel, it shows the meeting is in progress but there is no way to join it. I can dial the sip and get access to it but it is not a viable solution.

Hybrid Calendar is enabled and the OBTP is too in the settings. This is sporadic but have noticed a workaround that is quite annoying. Changing the Teams invite to plain text allows the Cisco device to detect it as a Teams meeting and the Join button shows up, sending it in the default HTML text the room won't show the Join button. 

Any help would be truly appreciated.

I had the same issue, Cisco Room Kit EQ + Cisco Room Navigator. The Join button wouldn't show up on the touch pad. The issue was intermittent but most of the time the button would be missing.

This was the fix:

PS C:\Windows\system32> Connect-ExchangeOnline

Set-CalendarProcessing Rsc_Mtg_MeetingRoomName -DeleteComments $false
Set-CalendarProcessing Rsc_Mtg_MeetingRoomName -DeleteSubject $False
Set-CalendarProcessing Rsc_Mtg_MeetingRoomName -AddOrganizerToSubject $False
Set-CalendarProcessing Rsc_Mtg_MeetingRoomName -ProcessExternalMeetingMessages $True
Set-CalendarProcessing Rsc_Mtg_MeetingRoomName -DeleteComments $False > Customer

PS C:\Windows\system32> Get-CalendarProcessing -Identity Rsc_Mtg_MeetingRoomName | select DeleteComments, DeleteSubject, AddOrganizerToSubject, ProcessExternalMeetingMessages

DeleteComments DeleteSubject AddOrganizerToSubject ProcessExternalMeetingMessages
-------------- ------------- --------------------- ------------------------------
False False False True

Having the same problem. Seems to be intermittent and not consistent. Has anyone else seen this?
Is this problem independent of type of controller (Navigator or Touch 10)? the webex hybrid calendar is in the cloud so that's where the invite is parsed. Just confirming.

It sounds like you are experiencing a compatibility issue between Microsoft Teams and the Cisco Room Navigator + Room Kit room system. This is a known issue that has been reported by other users as well. One possible cause of the problem is that the HTML code in the Teams meeting invite is not fully compatible with the Cisco device, causing the Join button to not appear.

One workaround that you have already discovered is to change the Teams invite to plain text, which seems to resolve the issue. Another possible workaround is to try using a different device to join the meeting, such as a laptop or mobile device, which may be more compatible with the Teams meeting invite. If the issue persists, you may want to reach out to Microsoft and Cisco support for further assistance. They may be able to provide more specific guidance and solutions to resolve the compatibility issue.

How exactly did you add the teams invite in plain text? Did you - the teams invite contains an embedded hyperlink so its not very straightforward

Here is my standard blurb for making this work: 

• Adjust the Exchange room resource mailbox settings to avoid common pitfalls.
  https://help.webex.com/en-us/article/qtrehbb/Known-Issues-with-Hybrid-Calendar-Service#id_83211
• Required. Do not delete the meeting body from the invite once accepted by the room.
  Set-CalendarProcessing -Identity “room name” -DeleteComments $false
  Note that anyone that has more than free/busy permissions to the room resource mailbox will be able to open the invite and join these meetings as if they were invited. You may want to adjust the default permissions on the calendar if this is a concern.
• Recommended unless privacy concerns prohibit it:
  Do not delete the meeting title so it can be shown within the room and the signage panel outside the door.
  Set-CalendarProcessing -identity "room name" -DeleteSubject $false
• Optional. Recommended if the title will be deleted so the room has something to show:
  Suffix the organizer’s name to the meeting title. For example, “Jonathan Schulenberg Test Meeting” with the subject or “Jonathan Schulenberg” without the subject.
  Set-CalendarProcessing -identity "room name" -AddOrganizerToSubject $true
• Optional. Enable this if you want users to be able to forward an external meeting invite to the room vs. creating a new invite and copy/pasting details into it:
  Set-CalendarProcessing -identity "room name" -ProcessExternalMeetingMessages $true
• If you have a link protection service such as Microsoft ATP, ProofPoint, etc. you will want to create exemptions for the meeting join URLs to avoid tripping Hybrid Calendar up. This is a common cause of failures since the RegEx match is performed against the HTML link href attribute, not the displayed text. I’m not aware of an authoritative source document for these but suggest starting with:
• https://*webex.com/*
• https://teams.microsoft.com/l/meetup-join*
• Google Hangouts is missing because I don’t have an example URL to look at.
• Zoom isn’t relevant here because the endpoints join those using SIP

Thanks for this Jonathan - thanks to your guide, we have the Join meeting button back on our systems! Much appreciated!
