Meeting chat unavailable until you join the meeting

[avpacheco]

I've been having a recurring issue where I cannot access the chat for a meeting scheduled though Outlook as a Teams meeting (not associated with any Team or Channel). Another user scheduled the meeting and wants to share meeting documents before the meeting begins. However, every time I (and other attendees) try to access the chat, I receive a message that says "Sorry, chat is unavailable until you join the meeting." I've tried recreating the issue on my own, and every time I schedule a meeting (whether through Teams or through Outlook), I don't run into this issue. The other user is typically scheduling meetings with 50+ participants, and in my tests I'm only inviting 1-2 participants. Could this be the difference? We want to be able to share the meeting documents before the meeting, but find it annoying to have to email them out when we could just utilize the chat.

Hi @avpacheco 

It’s worth noting that, although the Chat with Participants link is displayed in the invitation page before joining the meeting, this will not work.

So keep in mind, if you click on this link, you’ll get a message warning that ‘Chat is not available until you have joined the meeting’.

Chat is only available after joining the meeting

@Mr_Trust_A 

I'm a little confused by that because I have scheduled other meetings and attendees accessed the chat just fine before joining. Why is the chat unavailable sometimes and not others?

I would like to add that I am trying to start some pre-meeting notes. I am following the instructions from here: Take meeting notes in Teams 

They instruct me to access the meeting chat, which apparently is not possible until I join the meeting.

@avpacheco could it potentially be due to internal vs. external?

For example, when I'm invited to another meeting by someone internal (user on our tenant) I can access the meeting chat prior to the meeting.

However if it is an external person inviting me to the meeting, when I try to access the chat I get the message 'Sorry, chat is unavailable until you join the meeting'.

@Mr_Trust_A This is 100% NOT my experience.  We join chat before the meeting all the time to inform colleagues that a prior meeting will run over or share a bit of relevant info.

@Mr_Trust_A 

this is due to a new setting in meeting options
this only happens for us if we set 'peeple i invite only'

you also have the abilityt o allow chats in meetins only

Just gonna add this to the conversation as it explains what is happening right now (rolling out as the roadmap link says) https://office365itpros.com/2020/11/24/new-access-rules-teams-meeting-chat-membership/

Yes I just read about that that’s great for us as we are starting a new term with our students

The requirement to join the meeting first before th chat function is available is great

@Mr_Trust_A, @avpacheco 

Good day...!!!!

I saw your query and found an option to start group chat before the meeting. Go to your outlook calendar ---> select the particular meeting ----->then go to the "meeting"/"respond" menu in menu bar ---> click on "contact attendees" --->"Reply all with IM". Once you clicked on this option, team group chat will open up with all attendees. Hope this will help you. Also find the screen shot for better understanding.

Figured it out!     

You need to right-click on the Calendar invite in TEAMS -- not Outlook.    It gives you the option there. 

You can do the IM participants in Outlook -- It just doesn't give you the meeting header and include it as part of the meeting
