MacOS – Lync auto achieving correspondences in outlook “Conversation History” folder

See this link.

Basically, you have to edit the plist for Lync, and enter a registry key equivalent.

The explanation is below:

Basically, the equivalent to the registry keys for windows needs to be entered in the Lync config plist file on the mac, a file named MicrosoftLyncRegistrationDB.xxx.plist that you can find in ~/Library/Preferences/ByHost.

In it, you will need to create an entry for each segment of the reg key path for the DisableServerCheck flag (all lower case). It should look like this:

hkey_current_user\

hkey_current_user\software\

hkey_current_user\software\policies\

hkey_current_user\software\policies\microsoft\

hkey_current_user\software\policies\microsoft\communicator\

hkey_current_user\software\policies\microsoft\communicator\disableservercheck

The value for each of the path segments is "<>" and type string. For the disableservercheck flag, the type is "Number" and the value is 1.

You can use a plist editor (there's a few free ones for the mac, or you can also use Xcode) to edit the plist file. The screenshot below shows you how it should look like.

I just downloaded Lync from Office 365 and had the exact same problem. After a bit of googling I realised that my Lync version was 14.01 and there was an update to 14.09 available. Updating solved my log in problem. Very simple (And stupid: 1. Why does Microsoft not update the package at Office 365? 2. How can login be broken to start with?).
