Outlook distribution list update not updating

They do for my colleague sitting next to me, so I don’t think it is a server misconfiguration or something like that.

Is there any way I can force a manual update of the Offline Address Book (OAB) in Outlook or reset it completely otherwise?

If the update mechanism appears to be broken for you, it could be because of a corruption in your OAB or in your mail profile.

In that case, you can completely reset it by deleting the files making up the OAB or by recreating your mail profile.

Another way to make sure that you get a fresh copy of the OAB is by renaming the oab-files to when Outlook is closed.

They are stored in the following location: which itself holds subfolders with named after Account GUIDs.

The inbox had literally thousands of emails in, all of which had been handled and cleared away previously.

In Outlook 2013 and Outlook 2016, you’ll find that this option is no longer available as full details are also used to build the Contact Card.Rather than waiting 24 hours for Outlook to update the Offline Address Book on its own, you can force an update via the Send/Receive menu button.You can disable the option “Download changes since last Send/Receive” to make sure you get a complete fresh copy of the OAB but this could take longer to download.I'm wondering if anyone has anyone has any tips that could help me address this issue. Are you using web or public folder distribution for the OAB? I created an alternative OAB, connected it to the Default GAL, made that OAB the defualt OAB, and tried to download it through Outlook.
