Outlook OAB offline distribution


Our exchange administrator has made a mistake and delete all external contacts... Now he's recreated them but with the wrong policy (invalid mail addresses), and although this mistake was also fixed manually - the new OAB does not propagate to external users who are not connected to the LAN, and this time he does not know how to fix it..

Is there a way to send the OAB as file and MANUALLY replace the existing one in Outlook?

Thanks in advance

Are those user able to receive email using Outlook from outside the network? If yes, then it will update their OAB usually every morning around 5 a.m.

If you want to push the oab then run:
Get-OfflineAddressBook |Update-OfflineAddressBook

When you say it does not propagate to external users, is Outlook Anywhere configured in the environment?

Since I'm an end-used and doesn't have access to the Exchange/IIS in this case, I know for a fact that the OAB is not being synchronized properly using Outlook Anywhere, probably due to a firewall/IIS issue - and the sys admin is not care to solve it. SO i'm looking for a `creative` method to get an offline copy of the OAB and send it to the relevant users so I will be able to receive mail again!

If those users are using OWA, they should not face issue

If they are using outlook anywhere, then you need to ask them to update OAB manually over Email

You may create screen shots and send them step by step instructions over mail.

Alternatively you may try below TechNet Article to Manually deploy offline address book files.

Run Test Email autoconfiguration from Outlook and verifiythe OAB Url.If it is failing then make sure that autodiscover is working fine Externally

Export the contacts from Outlook in PST and import it back to External Client
