Blocking Outlook on the web offline access

[PMorgan_1116]

Hoping for some confirmation/clarification...

I believe I understand that both Set-OWAMailboxPolicy -AllowOfflineOn NoComputers and Set-OWAVirtualDriectory -AllowOfflineOn NoComputers can be used to prevent/block offline access using OWA.  If we are wanting to block offline access for ALL users (internal and remote), which is the correct cmdlet to use?  I guess I'm having trouble distinguishing exactly when each cmdlet would be appropriate.  Thanks in advance for any help!

You can use either. The first one gives you more granularity, as you can have different OWA Mailbox policies applied to different users. The second one is "global" toggle.
