I've been updating user images in AD over the last few weeks. For most users, that thumbnailPhoto attribute is pulled and viewed in Outlook correctly anywhere from an hour or so to 3 days after uploading the photo. For a handful, however, Outlooks sees some photos and not others even though it's been 3 weeks or longer since the photo has been uploaded.
Is it normal for it to take that long? Is there something keeping these users from seeing the photos?
I've tried manually downloading the global address list from their machine with no change.
