We are running Zimbra Release 8.6.0.GA.1153.UBUNTU14.64 UBUNTU14_64 FOSS edition, Patch 8.6.0_P3 on Ubuntu 14.04.(New Installation). We have created a Address book and shared to a internal users. we are able to see the contacts from the address book in the user login, but when he tries to compose a message and try to select the contact, nothing is visible. Only Global Address List alone is visible. This is a global issue for all users who are accessing the server.
Please help us to resolve this issue.
