This is an interesting issue we caught last week. For some reason permissions on the metadata share and application share were missing some key groups. Not sure why they weren’t configured or all of a sudden became un-configured but some key errors appeared when some one tried to initiate a live meeting session. Event ID 41038 reported an invalid metadata folder. Our main clue to resolve the issue.
Here is the link to permissions created during OCS pool creation in the metadata and application share.
So a quick tip is to check your permissions even if everything loads successfully during your OCS setup.
