I need advice on how to add a specific email address to the list of trusted senders. The main goal is for emails from a specific address to automatically download images and HTML content. I need to do this globally for all users. Is there any way to configure this in Exchange, or deploy it via Intune with a policy?

    Dear @Anand Bahuleyan,

    I hope you’re having a good day. 

    Yes, there are options to manage this centrally, but there is an important distinction between adding a sender to Safe Senders/Trusted Senders and forcing Outlook to automatically download images.

    Adding a sender or domain to users' Safe Senders lists can be managed centrally through Exchange Online PowerShell using Set-MailboxJunkEmailConfiguration and the TrustedSendersAndDomains property. This is the closest Exchange Online provides to an organization-wide trusted sender configuration.

    For example, administrators commonly use Exchange Online PowerShell to populate Safe Senders for multiple mailboxes rather than asking users to configure them individually. However, the second part of your requirement is where things become more complicated: Automatically downloading images and external HTML content is primarily controlled by the Outlook client, and behavior varies between Outlook for Windows, Outlook for Mac, Outlook on the web, and Outlook Mobile.

    Because of this, there is no single Exchange Online setting or Intune configuration profile that guarantees automatic image downloads from a specific sender across all Outlook platforms.

    My recommendation would be:

    1. Use Exchange Online PowerShell to centrally add the sender/domain to users' TrustedSendersAndDomains configuration.
    2. Verify which Outlook clients are in use (Windows, Mac, Web, Mobile), because image-download behavior may still differ depending on the client.

    I hope this helps clarify the available options and the limitations involved.

    Warm regards,
