With the Latest releases and changes in D365 Customer Service, new tab has been added in a Queue Record. When Existing Queue is Opened, user cant save the record without ticking Omnichannel Conflict Tab. If by mistake user ticks it as Yes then the Queue gets converted to Messaging Queue(Advanced Queue), there is no option to revert it back and product team confirmed, its not possible to revert from backend as well. The Only option is to create new Queue. If the Queue is in use since years and is used in various places e.g. External Integration, Processes(Flow, Workflow Plugin etc) then whole functionality will break.

This isn't and ideal solution and as a human anybody can make a mistake by setting Conflict tab to Yes and Save the record. There is no warning either that Queue will be converted to messaging Queue.

Steps to Reporduce

1. Login to Dynamics
2. Open Advanced Settings -> Settings -> Business Management-Queue
3. Open any existing Queue and go to Conflict Tab (Queue Type will be null)
4. Set to Yes and save
5. Queue will be converted to Messaging Queue
6. Reverting Back to Entity Queue is not possible

User should have option to revert it back
