Disable Offline Mode

New Outlook

In the New Outlook, users can turn on Offline mode, which causes sent messages to be stored in the Outbox. When Offline mode is later turned off, these messages are sent automatically—without involving any add-ins, including the Zivver add-in. As a result, the messages are not classified or secured by Zivver. To avoid this issue, follow the steps below to disable the option for Offline mode in the New Outlook settings.

Note

Please be aware that there are scenarios where disabling Offline mode in the OWA mailbox policy does not work. For example, when your organization has users who primarily log in to the New Outlook with email accounts that are associated with a different OWA mailbox policy — for instance, one from another organization.

Prerequisites

• Exchange Online admin permissions.
• PowerShell is installed on your machine.
• ExchangeOnlineManagement module is installed in PowerShell on your machine.

Procedure

1. Open PowerShell.

2. Run the following command to connect to Exchange Online:

   Connect-ExchangeOnline
   

   A pop-up appears, prompting you to enter your admin credentials.

3. Run the following command to list all existing OWA mailbox policies:

   Get-OwaMailboxPolicy | Format-Table Name, Identity
   

4. Run the following command to disable Offline Mode for the OWA mailbox policy:

   Set-OwaMailboxPolicy -Identity "<policy_name>" -OfflineEnabledWin $false
   

   Replace <policy_name> with the name of the OWA mailbox policy you want to modify. If you want to disable Offline Mode for all policies, you have to run this command for each policy listed in the previous step.

5. Run the following command to verify that Offline Mode is disabled:

   Get-OwaMailboxPolicy -Identity "<policy_name>" | Format-Table Name, OfflineEnabledWin
   

   Replace <policy_name> with the name of the OWA mailbox policy you want to verify. The output should show OfflineEnabledWin as False. Example output:

   Name                                         OfflineEnabledWin
   ----                                            ---------------------
   OwaMailboxPolicy-Default    False
   

6. Run the following command to disconnect from Exchange Online:

   Disconnect-ExchangeOnline
   

7. Verify that users can no longer enable Offline Mode in the new Outlook by going to Settings > General. The option to enable Offline Mode should no longer be available.
