Hi Pat Berscheid,
You may try the following suggestions.
1. Install the latest update for Lync 2013.
2. Try disabling Outlook cached mode, put it on Online mode and then close Lync and open it again.
If the issue still persists, you may try this.
a.
Navigate to X:\share\1-WebServices-1\ABfiles\000000000\000000000 folder. (ABS file share)
b. Delete all the files in this folder.
c. Run
Update-CsUserDataBase to force Back-End to re-read all the user-related information stored in Active Directory Domain Services.
d. Run
Update-CsAddressBook
e.
Delete local cache files on client computer.
%userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\sip_UserName@Domain.com
f. Sign in Lync and wait for the Lync client to download the latest Address Book.
Hope this can be helpful.
Best regards,
Eric
