So I’ve been working on a client where we needed to push out some settings via registry key as there was no corresponding in-band provisioning.  So I decided to take to the Bing’s and see if I could find them all.  I found Tom’s blog:

Which gave me the list of possible values.  What I wasn’t sure about was what the values would need to be and then found a few keys that Tom didn’t have in his blog post.  So I decided, why not go through the client page by page and see if I could find each registry key, what values would be supported and of course find the corresponding set-csclientpolicy value.  Why would I do this you might ask?  Because I’m a nerd and find this pretty neat.  So this will take a few posts to get through it all.

A few basics to be aware of.

All of the registry keys will be found in the HKCU:SoftwareMicrosoftOffice15.0Lync

Almost all of the values are DWORD values.  Unless otherwise noted that is what they are.

The values are 0 = unchecked/disabled and 1 = checked/enabled.  Unless otherwise noted.


Personal Tab


#1 Automatically start Lync Client

#2 – Saving Conversation History

This one gets asked all the time and I’ve confirmed, this data cannot be set via the registry.  This information, if not set by your administrator, is actually stored in the back-end database.  As a test, try the following: Go to client #1 and uncheck Save IM conversations … go to client #2, log out of Lync and log back in (with same user of course) and you will see it’s unchecked. 

One item to remember is that EnableIMAutoArchiving just stops the automatic saving of IM’s to conversation history.  A user could still use the CTRL+S to save it themselves.  You would need to also enable the DisableSavingIM client policy tag to completely stop saving of all IM’s.

You can learn all about this field here:

I’m in the process of finishing up this table.  I’ve found some old references for OCS 2007/R2/2010 but they don’t apply to the 2013 client.  So I’m going to continue to fish through the registry for them.  Once I’ve finished those I’ll move onto the next screen.
