Overall, Microsoft Outlook's support for BIMI is limited and inconsistent. While Outlook.com (the web version) may support BIMI, the desktop application generally does not. Microsoft promotes Actionable Messages as an alternative branding solution. Past logo display methods like Bing Pages and Brand Cards have been discontinued. BIMI adoption faces challenges due to varying support across email clients, the complexities of DMARC implementation, and the absence of widespread support in desktop Outlook. Some experts suggest integrating Verified Mark Certificates (VMC) with Microsoft Actionable Messages (MAM) to mimic the BIMI experience, although this can be expensive and requires a trademarked logo.

The consensus is that Microsoft Outlook's support for BIMI (Brand Indicators for Message Identification) is limited and inconsistent. While Outlook.com (the web version) may support BIMI, the desktop application generally does not. Microsoft previously experimented with logo display methods like Bing Pages, but these have been discontinued. Microsoft promotes Actionable Messages as an alternative branding solution. The adoption of BIMI across email clients is hindered by its patchy support and the complexities of DMARC implementation. Community feedback and expert opinions confirm the lack of comprehensive BIMI integration within Outlook, suggesting that relying on BIMI for brand visibility in Outlook may not be universally effective.

While Microsoft has not directly implemented BIMI (Brand Indicators for Message Identification) in Outlook, they have explored alternative methods for brand display. One discontinued approach involved 'brand cards' through a now-redirecting website. Currently, Microsoft supports Actionable Messages as a way to display branding. Integrating Verified Mark Certificates (VMC) and BIMI with Microsoft Actionable Messages (MAM) provides an alternative that mimics the BIMI experience, though this may require a trademarked logo and can be costly.

Documentation from various sources offers insights into Microsoft Outlook's support for BIMI. The BIMI Group specifies that Outlook.com supports BIMI but lacks details on the desktop app. Microsoft's documentation highlights Actionable Messages as a branding alternative without mentioning BIMI support. Documentation from DigiCert and Entrust provides general BIMI information and requirements, but omits specific details about Outlook support, focusing instead on Verified Mark Certificates (VMCs) and brand ownership verification.
