OAB Users Photos

Question

Hi, I'm going crazy with the users's photos in Outlook (2019) OAB. We are in an Hybrid environment : photos have been sent to AD, sync with AAD Connect, they are present in AAD. Mailboxs are in EXO. No problem with the Webmail & Online Mode : everything is up to date. But when we use Outlook in Cached Mode, photo for some users is not display, for others it's an old one. Already try to : Clear Outlook Cache Recreate the profil Modify the "ThumbnailPhoto" attributes of OAB from "Indicator" to "Value".

After others research, I found that Users impacted has the value "hasPicture" set to False in their mailbox, while a photo is configured. Need help about this issue.
Regards.

Hi @WebGTA ,

When you are using Outlook in cached Exchange mode, the photo change may not take place immediately as it takes some time for OAB to update itself. You can force an OAB update and see whether it helps.

To force an update of the Offline Address Book (OAB) in an Exchange environment, you can follow these steps:

1. Update the OAB in Exchange Management Console (EMC): In EMC, right-click the OAB and select “Update”. This generates a new copy of the OAB.
2. Restart the Microsoft Exchange File Distribution service: After updating the OAB, restart this service on your server. This distributes the new copy of the OAB.
3. Download the OAB in Outlook: In Outlook, click “Send/Receive”, then select “Download Address Book”. This downloads the new OAB to your local machine.
