Verify DKIM and SPF in Outlook

Hi,
Is there an Add On available for Outlook that will verify the received message for DKIM signature and SPF such as is available for gmail (in fact it is not an add on, but built in functionality in gmail).
The functionality we need is that an end user right clicks a message, choses "verify" (or whatever) and then sees the results:
DKIM - PASSED, FAILED or NOT PRESENT
SPF- PASSED, FAILED or NOT PRESENT
I know that this info is present in message headers, but it is cryptic and it is not possible to verify (easily).
The reason we need this functionality is because users often receive fishing emails, and simple verification would greatly increase security.

Thanks in advance.

Hi @DUSKOSAVATOVIC-4532
The only add-on I am aware of is the MHA. I use this all the time and its really nice.
It's not flashy but works

Thanks Andy. The add-on works for Microsoft's account. I have tested it on outlook.com. However, it doesn't work for non-Microsoft accounts. The reason is that it pulls headers from the server via EWS and REST, not from the message downloaded to Outlook. Unfortunately, it doesn't work for on premise Exchange either. Do you know of any third party solution that would provide similar functionality on Exchange server?

Hi @DUSKOSAVATOVIC-4532
Thanks for visiting our forum, here we mainly focus on general issues about Outlook desktop client, so I'm afraid that we may know little about third party add-ins in Outlook.

As you have mentioned above, the MHA add-in works for Microsoft's account but not for other email account. I really did a lot of research about your issue but failed to found other similar add-in. However, as I know, the MHA add-in also have web version(https://mha.azurewebsites.net/) and we could use the web version to analyze all the message headers we have. Unfortunately, we need to manually copy the message header to the web for analysis which might be inconvenient for you, just as a workaround for you to refer.
