Query on Address book

Question

Hi All,

I have renamed the display name and email address of an exchange online distribution list. I believe the address book updates once every 24 hours. Is it possible to manually update the offline address book so that users can see the new DL display name and email address.

Hi, @Glenn Maxwell

Yes, you can do manually update the Exchange Online Offline Address Book (OAB) so that users can see the new distribution list display name and email address.

Here are two things you can try:

1.Run the following command to force an OAB to be generated:

Update-OfflineAddressBook -Identity "Your OAB Name"

Once you update your OAB, you need to distribute it. Run the following command:

Get-OfflineAddressBook | Update-FileDistributionService -Identity "Your OAB Name"

In addition, you can manually download the updated OAB, as shown in the following figure.

2.The Microsoft Exchange Mailbox Assistant service on Mailbox Role is responsible for generating OAB. Restarting this service generates all OAB’s defined in the environment on a specific mailbox server, if it’s hosting an active organization mailbox.
