Recently it was notice that the co-existence mode is different from some users in our organization?
One particular user is onco-existence mode for Teams Only Modewhile others are onIsland Mode only.
I have also tried to change the Co-existence mode from Teams Only mode to Island mode but I got an error that says"This user is hosted in the cloud and needs Teams only mode to assign an instance of TeamsUp grade Policy"
Do you have an idea why I cant change that to Island mode.
I have attached a screen shot of the error message.
