Hi,
How exactly you "added Address book in outlook for all of my users"? If possible, please share your steps with us.
If you'd like to access these email addresses when you're working out of the office or using Outlook in offline mode, you can choose to add all these email addresses to your local contact folder by following the steps below:
- Open the "Address Book" dialog from the ribbon, then select the specific address book from the drop-down.
- Select all the contacts in the address book, right click and select "Add to Contacts".
This way, you will have the most up-to-date information from Active Directory in your local address book.
Please feel free to let me know if this doesn't help.
Regards,
Ethan Hua
