I am trying to resolve an issue where an employee doesn't see certain user pictures when composing or receiving email. Our organization has small photos of all our users that appear on the bottom section of an email. I am not an exchange admin, but just trying to get troubleshooting ideas or thoughts on why certain pictures don't show up. For this particular user, her own picture along with 5 other people in our organization, only show the blank default "picture" (the white outline image of a person against a grey background). All of our other users have no problems with either her picture or the other 5 people she has a problem with. It's only her account...and only those five other user pictures that don't show up.
Troubleshooting steps I've already taken:
I had this user log into one of our loaner laptops and configured outlook for her. The problem followed her to this and another computer...so not computer specific.
Deleted her ost file, and when I opened Outlook for the first time since deleting her ost, pictures showed up once she received an email, but when composing an email, pictures did not show up. I closed outlook and reopened it and now the pictures (for those certain people) don't show up any longer. I deleted her accout and outlook profile and the same thing happend.
