Managing the New Exchange Online OWA Document Collaboration Feature

Posted on


For those Office 365 Admins who are responsible for Outlook Web Access (OWA) and the new Document Collaboration feature, allowing Office 365 Web Apps to render the attached document and provide document editing and collaboration. While this is a great new addition, as Exchange previously would not allow or provide the ability to edit these attached documents, as the Exchange Information Store did not have that capability.  So now instead of having to save the attached document to a local PC, fileshare, SharePoint Online, etc and then edit the document, the attached documents can now have full editing capabilities, which is FANTASTIC!


So your next question might be “How do I manage this?  While I like this capability, my users may not be ready, I need to get everyone trained on this before rolling this out. How do I manage this?

Steps to Manage Enablement/Disablement of OWA Document Editing

  1. Connect to Exchange Online via PowerShell
      1.  $LiveCred = Get-Credential
      2. $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $LiveCred -Authentication Basic -AllowRedirection
      3. Import-PSSession $Session
    2. Once connected, you will manage this OWA Document Editing Capability by managing the OWAMailboxPolicy attribute for the Exchange Online tenant level for all users:
      1. Tenant
        1. Set-OwaMailboxPolicy -Identity OwaMailboxPolicy-Default -WacViewingOnPublicComputersEnabled $False -WacViewingOnPrivateComputersEnabled $False

Note – When using this new feature notice that the attached document has three elipsys (dots) which give users the ability to select if they want to download, otherwise clicking the document will open the attached document into Editing View:
