Hello All,

We have a concern where we are unable to see mail contacts in the distribution lists. Like we have hundreds of mail contacts with the name of "Franchises", but we are able to see only 3 from different DL's. But when we check for the members of these DL's from AD or exchange management console we are able to see all the members, and when searched from outlook 2013 GAL, we are able to see only 3, rest cannot be found. Outlook address book has been download multiple times but issue still persists.

Also note we have 2007 and 2013 working at the same time with few hundred users to migrate, however the major chunk has been migrated. Also we tried updating the distribution list (exchange version 0.10) but it also did not worked out.

Any idea what could be be done in order to make these mail contact available as member to distribution groups.

Hi ,

Make sure the offline address is up to date on the exchange server ?

Get-OfflineAddressBook | fl *last*

If not update the offline address book by using the below mentioned command.

Get-OfflineAddressBook | Update-OfflineAddressBook

Hi,

According to your description, I understand that most contact named of Franchises not show in GAL, however it show as members of these DL's from AD or exchange management console.
If I misunderstand your concern, please do not hesitate to let me know.

First, please try to below command to update address list as Nithyanandham mentioned, then check in OWA and Outlook client:
Get-AddressList | update-AddressList
Get-GlobalAddressList | update-GlobalAdressList
Get-OfflineAddressBook | Update-OfflineAddressBook

If the issue persists, please run below command to check whether the value of HiddenFromAddressListsEnabled  is enabled.

Get-Mailbox | Where {$_.HiddenFromAddressListsEnabled eq $true} | FL Identity,Name,HiddenFromAddressListsEnabled

If so, we need to change it to False and try above command to update address list.

Thanks
