Hi ​@Dimitri 

The root cause is that the Teams Lucid integration requires users to be authenticated with Lucid, even if the document permissions are public.

As a result, non-licensed or external users are unable to access the board directly within Teams, open it in their browser is only possible for now.

Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards

Thanks for replying Huma - that’s a real shame and one of the main reasons to use the share in team's function! 
When facilitating a board, the best way to grab people's attention is to share in teams and collaborate on a single interactive piece of glass. How can we request this as something to resolve? Adding everyone in the team's meeting as a guest to the board without a lucid login would solve this and must be on someone's roadmap - if it isn’t could it be? 

Hi ​@Luke T thank you for chiming in! Thank you ​@Dimitri for your post and ​@Humas1985 for your help here! I would be happy to provide some clarification when it comes to the MS Teams integration and non-Lucid users. 

A workaround here could be our Guest Collaborators functionality. When adding guest collaborator links into MS Teams (either via pasting directly or using the insert link option), non-Lucid users can view previews of the documents (as long as they click on the carat to expand, otherwise no preview will be shown). To interact, they will need to click "Join now" which will open a link outside of MS Teams and bring them directly to the document. 

For channel tabs and calendar tabs (which would allow a logged-in user to interact directly with the boards while staying in MS Teams), those look to only be functional for logged-in users.

I hope this helps! Cheers

Thanks, Zuzia - that’s the problem though! Its outside of the team's window. The best collaboration takes place in single windows. Ive used it with other solutions and it speeds up collaboration lots! IT would be great to not have to work around this restriction and have it supported in Lucid.

Hi Huma,

Thanks for the explanation.

Agree with Luke, the key user story here is:

As an authenticated and licensed Lucid user, I need to engage my non-licensed user on a teams call via a seamless share and collaboration session within one interface.

1. Licensed Lucid user, runs a teams call and invites a non licensed Lucid user
2. Licensed user wishes to use the Spark board to collaborate, brainstorm and draw with the non-licensed user
3. Licensed user clicks share board, either prepared before call or on the spot
4. Non-licensed user can see the board and can either interact with the board or at bare minimum, see the licensed user’s input.
5. Once non-licensed user leaves the call, the permissions for editing the board are lost and the licensed user can either share the link via other channels (email, message etc.) or keep it private to his/her own usage.

Otherwise, the integration has limited value, and it’s just faster to share screen on a browser window and send the guest a link that does not require authentication, defeating one of the main integration points for intra-Teams collaboration per call.
