How do I customize invitee profile picture in entra id b2b email invitation

Question

I use bulk invite when inviting external users. We have an admin user in entra id that initiates the bulk invite process. The user has a set profile picture, however, the email sent doesn't load the admin's profile picture.

Sample Invitation

Admin Profile Image

Looking at the documentation, it says that the profile image should be included in the email if set.

Am I doing it right? Or is there any documentation that I should refer to?

Hi @Bon Macalindong ,

I would first recommend ensuring that your image isn't too large. The thumbnailPhoto attribute can store a user photo as large as 100 kilobytes. Exchange Online accepts only a photo that's no larger than 10 KB from Entra ID/Azure AD. To be on the safe side, you can shrink the photo to 1080p wide and 72ppi.

I have also seen a few users report this issue due to accessibility settings in Outlook conflicting with the image rendering, so I would double-check these settings too. You can try temporarily disabling accessibility features to troubleshoot this. https://support.microsoft.com/en-us/office/make-your-outlook-email-accessible-to-people-with-disabilities-71ce71f4-7b15-4b7a-a2e3-cf91721bbacb

I would recommend testing by opening the mail in the Edge browser and ensuring that attachments are allowed under Settings > Mail > Layout.

Otherwise the inviter’s name and profile image should be included if they have one set up in Azure.
