Coexistence mode defined by Microsoft and cannot be changed.

Question

Hey guys!

I'm trying to change the coexistence mode between Teams and Skype so that members of my organization who are still using Skype can communicate with the new members who only have access to Teams.

But when trying to change modes, I am blocked by the following message:

When trying to send a message from teams to skype I get the following error:

(my teams is in the pt-br language)

"We ran into a problem sending your message. Please share diagnostic code 504/1008 with your admin to help them troubleshoot the issue."

When trying to send a skype message to teams I don't have any error return from skype, but the message doesn't reach the destination.
