Short and sweet post, I have been recently deploying a Skype for Business Enterprise Pool with Always On and run into the follow error
Chapter 2. Error
Checking for Compatibility of the database file location on the server instance that hosts the secondary replica.

Chapter 3. Solution
This issue was caused by the CsData Folder locations been present on the Secondary Replica, if you create the folder locations on the Secondary Replica and re-run validation all tests will pass successfully then you can continue. You will be able find out the folder locations by clicking the word “error”
