Hi, we are looking for some instructions on how to disable OWA for all our users. This can be done for each users, but is there a way to do this for all users with something like PowerShell? Any advice / suggestions would be helpful. Many thanks
You can:
Disable the OWA app pool on each exchange server in IIS
or run in P to disable for all
Get-Mailbox | Set-CASMailbox -OWAEnabled $false
Many thanks, much appreciated.

Great to see that your query has been answered. Below is additional link about disabling OWA for reference: Use Exchange Online PowerShell to enable or disable Outlook on the web.
