Microsoft Teams Guest Users Chat Tab Missing

Been seeing some rumblings around Tech Community about guests not being able to chat in Microsoft Teams even thou Guest settings are set to allowed. After some troubleshooting and testing I had a hunch that it could be the coexistence mode settings and sure enough it was.

Cause: Skype Coexistence Modes

In my test scenario I switched my tenant over from Teams Only to Skype Only and waited overnight, and I woke up to a missing chat tab with my guest user. So we definitely have a root cause for the issue. The question is it by design? I Expect the other two Skype coexistence modes to also effect chat for guests.

Work Around: Teams Only Coexistence Mode

A work around would be to set your users that should be Skype Only manually to Skype Only coexistence mode per user. Once this is set, I personally would give it some time to bake. Next switch your Org setting to Teams Only. This should now revert the guest user to be able to chat and maintain your users upgrade mode.

The side effect to this method is your new users will be provisioned into Teams Only mode. So you would have to remember to change their coexistence mode when creating their accounts. This could also cause delays in the message routing as well so you will want to plan accordingly.

Conclusion

So far I haven't received any feedback on this item but I do not think it's by design. Not sure if it will get fixed or not, but right now the work around is the only method for allowing guests to have chat. This seems to have started appearing recently since the updates to the Coexistence Modes starting to enforce their intended behaviors (Disabling chat etc.). 

If I get anymore information about this I will update this blog. 

Updated Teams Out of Office Presence Behavior

Recently I went on a few day vacation and happen to notice some new changes to how presence works when Microsoft Teams automatically sets your status to "Out of Office" while using Automatic Replies or adding Out of Office meetings to your Exchange Online calendar.

Lets take a quick dive into the history of this feature and what has changed.

Previous Exchange Online OOF Presence Integration

Back in April of last year Teams released an update that would set your Teams status to Out of Office anytime you set Automatic Replies via Outlook/OWA or scheduled an appointment on your calendar with the "Show as" set to "Out of Office". This would hold your status as "Out of Office" throughout the duration of the event with the purple icon along with your Automatic reply if one existed shown below

Many users would complain that they couldn't change their status and that they were traveling for work and originally were confused by this when it first hit Teams. I never realized how many people used meetings in their calendars to block off their Out of Office until this feature launched. This caused some behaviors to be adjusted and left many with frustration of how this forced effect worked. The Teams team seems to have taken a good step closer to solving these exact scenarios.

Updated Exchange Online OOF Presence Integration

I'm not 100% sure when this feature came into play, but I would bet it was with the custom status update recently since this new integration disables the custom status so I think it makes use of it to make this work in this new way.

When you set your Automatic responses or OOF calendar meeting, when Teams polls this information (seems to be roughly every hour) it will now set your status in Teams to a new %CurrentStatus% - Out of Office format. What this means is you can now set your status to Available/Busy/DnD while OOF is active and you will get new status icons (white background) indicating your current status. You also get the same Automatic Reply message as well on hover cards.

Your status is set to the default purple icon and "Out of Office" status for all away statuses including being idle.

The new out of office statuses in Teams: 

What this means is you can now be out of the office and actually see if people are available for communication. This comes in handy in scenarios where people are out of home base, but traveling to customer sites and set their OOF for the trip and they still want their availability to show to colleagues. This is also useful if you want to to show your availability because you don't manage your work life balance properly and for some reason want to work when you're on vacation :).

Other Exchange Online Presence Integration 

It doesn't appear that the other presence integrations have been messed with at this point, such as your status being set to Busy when you have a meeting in your calendar etc. I

t's good to see Microsoft starting to tweak and improving some of the little things throughout the Teams product and hopefully we will see many more like it in the coming months.
