A. B. C. D.C.
The correct answer to the question is D. Change the coexistence mode to Skype for Business with Teams collaboration.
Explanation:
The coexistence mode determines how Teams and Skype for Business interact with each other during the migration process. In Islands mode, users can use either Teams or Skype for Business for communication, and the chat and calling experience is the same for both applications. However, this can lead to confusion for users who are not sure which application to use for communication. Therefore, changing the coexistence mode to Skype for Business with Teams collaboration will ensure that all users can communicate with each other without missing any messages.
Option A, ensuring that all users are signed in to either Microsoft Skype for Business or Microsoft Teams, is not sufficient to ensure that users do not miss chat messages. If users are using different applications, there is a risk of missed messages.
Option B, changing the coexistence mode to Teams only, would not allow Skype for Business users to communicate with Teams users. This would result in a communication gap and lost messages.
Option C, ensuring that all users have both Microsoft Skype for Business and Microsoft Teams installed and are signed in to both applications, is not necessary. It would be confusing for users to use two separate applications for communication, and there is a risk of missed messages.
Therefore, the best option is to change the coexistence mode to Skype for Business with Teams collaboration. This will allow all users to communicate with each other, regardless of which application they are using, and will ensure that no messages are missed during the migration process.
