Outlook mobile Inbox contact icons

[Simon Barratt]

Does anyone know what controls the icon now displayed in Outlook mobile for iOS?

I am seeing many emails now using the companies logo, including Microsoft.

How do I configure my company logo to appear in this way?

Thanks

Did you find a solution ? I have the same question.
Thanks for answering my question.

@Marc_de_Leuwfrom what I was able to understand, it is part of the business branding initiative MS has in beta. http://business.microsoft.com

Exactly what I was looking for :)
Do you know if this beta program is also responsible for the company-specific icons in the Microsoft Authenticator?
