Updating offline address book
First, the original touchscreen-based client which started in OCS on the CX700 and was updated for Lync.
If you have had the Lync client running continuously at any time for more than 2 hours and this synchronization message is still displayed, there is likely an issue.Four common problems and their solutions are listed below.1] The Persistent Message “” in the Lync Client When the Lync client is run for the first time it chooses a random time between 1 – 59 min to download the Lync address book (from the FE server).Previously the only supported devices that used the Office Communicator Phone Edition client were the Microsoft reference-design “Tanjay” family of devices: the Polycom CX700 and LG-Nortel IP8540.Both phones were identical and used the exact same software so a single installation package was distributed and updated on a regular basis.It was supported in HMC 4.5 – Exchange 2007/Exchange 2010 /hosted – Both the products were dropped by Microsoft.
From Exchange 2010 SP2 Global Address list segregation was supported commercially and internally, It was easy to view and manage through Management Console.
Lync Server 2010 now has multiple versions of the update package, as they are both different clients (with different interfaces and features) as well as different device designs between vendors.
The Lync Phone Edition client now has two different interfaces.
This makes it possible to lock down any given user to viewing contact details only of the employees they are supposed to see, creating an impression that the user is in a different Exchange / Office 365 organization. It was possible to do this in on-prem Exchange 2010, Exchange 2007, and even as far back as Exchange 2003.
But it is a somewhat new concept in Exchange Online and Office 365, and there isn’t a great deal of information on it out there yet.
Scenario 1: Two Separate Entities in One Exchange Organization or Two Separate Departments in One Exchange Organization.
