OME - Attachment blocked for non-Office 365 receivers

Hi,

 

I already created a support ticket in the portal, but have been waiting for two days for the engineer to "ask around".

 

I executed the following powershell commands to allow XML files in the Outlook portal, this works fine:

Get-OwaMailboxPolicy | Set-OwaMailboxPolicy -BlockedFileTypes @{Remove = ".xml"}
Get-OwaMailboxPolicy | Set-OwaMailboxPolicy -AllowedFileTypes @{Add = ".xml"}
Get-OwaMailboxPolicy | Set-OwaMailboxPolicy -BlockedMimeTypes @{Remove = "text/xml", "application/xml"}
Get-OwaMailboxPolicy | Set-OwaMailboxPolicy –AllowedMimeTypes @{Add = "text/xml", "application/xml"}   

 

But now the user sends a OME encrypted message to a receiver not using Office 365, attaching an XML file. The receiver gets an HTML page which the receiver logs in to and can view the message. This is also fine.

 

But when the receiver wants to download the XML file from the OME encrypted message it is blocked by "OWA"...

Does anyone have a solution to this?

This would force us to an alternative solution.

Zipping the XML file is no option for us.

Afaik OME uses a "sandbox" OWA environment, meaning the changes you have made to the OWA policy will not apply there. Best ask this question on the AIP Yammer network where all the AIP/OME folks are at: https://www.yammer.com/askipteam/
