The source image coming from AD was/is low quality.ĮXO user photos can be updated by users individually or if high res source photos are available this import can be scripted. Out of scope of this discussion for now.Įxchange Online user photo is low quality (and in turn so is the SPO photo and SfB photo) Uses the high resolution Exchange image if available, otherwise uses the AD thumbnailPhotoĪlso stores its own photo. PnP image upload solution uploads these as 200 x 200. I have seen as small as 120 x 120 and as large as 300 x 300. Large changes depending on the source image but is always square.
NOTE: Updating user profile photo via Delve profile is actually updating EXO profile photo and not performing any actions directly in SharePoint Online. Sometimes we see that a user must ‘touch’ their profile before the sync will be performed. It generally takes up to 72 hours to see changes to EXO photo here. Three renditions of the EXO photo are automatically created in SharePoint after upload to EXO. If not provided, Exchange will reference the AAD thumbnailPhoto in some instances but only if the thumbnailPhoto is less than 10Kb. Provided manually by users or a bulk import can be scripted if source photos can be located and named appropriately. Usually synced from AD DS via Azure AD ConnectĮxchange Online as property of the mailbox On-premises AD DS in the thumbnailPhoto attribute
User photos: the diagram User photos flow in Office 365 Where applications store and fetch user photos Changes such as these will continue to evolve). Prior to the Delve user profile page, the SharePoint user profile page referenced images stored in SharePoint rather than Exchange. Please note the date of this article (August 2016) and be conscious that Office 365 is changing rapidly and the following recommendations may have changed (e.g. It aims to demonstrate where user photos are stored and where different applications fetch user photos from (if they don’t store the images), and leads to some recommendations about user photo synchronisation. I have put together a flow diagram to represent how this actually works. Photos are stored in Active Directory (AD) on-premises, Azure Active Directory (AAD), Exchange Online (EXO), SharePoint Online (SPO), and at first appearances possibly elsewhere as well (where does my Delve profile picture live, what about my Skype for Business (SfB) avatar?). The user photo story in Office 365 is not so straight forward.
