Actionable Messages from Flow Approval not working in Outlook Web or Outlook 2016 for O365 users.

Hello,

I have a client where actionable messages are not working in outlook 2016 or web mail for the o365 users. You get the approval email, but seems like actionable messages are blocked. It works fine on my tenancy and other clients but not on his.

I think I know the issue, seems to be the barracuda spam filter. My question is what needs to be white listed in this case? Microsoft.com? or would maccount@mmicrsoft.com work? or maybe something else?

this is the main issue I believe, the following shows up in the mail properties "Authentication-Results: spf=fail (sender IP is <barracuda IP>)
smtp.mailfrom=microsoft.com"

Thanks,

Robby

Hi @rgaron,

Could you please share a screenshot of your issue?

Do you want to make a response to the approval email from Microsoft Flow within Outlook client or Outlook web?

I have made a test on my side and the actionable message works well. My flow's configuration as below:

The flow works successfully as below:

Please check if your Outlook client version have met the requirements for actionable messages. More details about Outlook client version requirements for actionable messages, please check the following article:

Outlook client version requirements for actionable messages

Best regards,

Kris

Hi Kris,

Thank you for the response.

How is your Exchange setup, hybrid or just cloud? My client with the issue is setup as hybrid.

My client's mail flow is setup like this: inbound mail goes to barracuda -> Office 365 (Exchange Online) -> On Prem Exchange depending on the user.

I setup the same setup over weekend and my actionable messages work fine, so not sure what the deal is and I really didn't do anything special, it just worked.

Here is a screenshot of my clients approval. It's basically the same if you scroll down to the bottom of you approval email you have screenshot here and click details. The approval is being done via Outlook Web.

This has been solved!. Ended up being a setting in Barracuda Cloud Control that my client uses for email security.
See below the screen shot. It's called content intent, by default this is set to Off. You either need to turn it off or set the Intent Domain Policy to ignore microsoft.com as shown below in the screenshot.

This also should not be factor when Flow allows you to specify the from field (providing you use an internal email address, which I believe you can only do anyhow) for the Approval action which I understand they are working on. Currently it's hard coded as coming from maccount@micrsoft.com (external account).
