Unset OWAMailboxPolicy
Introduction
OWAMailboxPolicy
no longer needs to be set manually with Powershell commands as it is now part of the default OWA functionality. If you have set up this policy manually for your users, you should disable it to ensure users won’t encounter unexpected behavior when sending emails from the OWA.
Disable OWAMailboxPolicy
To disable OWAMailboxPolicy:
Connect to Exchange via PowerShell
Import-Module ExchangeOnlineManagement Connect-ExchangeOnline -UserPrincipalName admin@domain.com
Check the available OwaMailboxPolicies and their value for
OnSendAddinsEnabled
. Make sure the default for this value is set toFALSE
:
Get-OwaMailboxPolicy | fl name, onsendaddinsenabled
Change the OwaMailboxPolicy for every user:
Get-User -Filter {RecipientTypeDetails -eq 'UserMailbox'} -ResultSize Unlimited | Set-CASMailbox -OwaMailboxPolicy OWAMailboxPolicy-Default
Close the Connection to Exchange:
Disconnect-ExchangeOnline
Cancel/delete the task to give new users the OwaMailboxPolicy
- Open the Windows Task Scheduler
- Search for the task that enables OwaMailboxPolicy
- Disable or delete the task
