Hi,

Please try this:

In the upper right corner of the Lync main window, click Options (gear icon).

In the Lync - Options dialog box, click Personal.

Clear the Save my Lync contacts in my personal contacts folder on the Exchange server check box.

Having the same problem... tons of duplicates... no option in 2013 to deselect.

Any other solution?



Lync Server 2010 back-end should be CU5 or greater, then:

• Set-CsClientPolicy global -EnableExchangeContactSync $False
• Delete Lync Contact folder from the Personal contacts in Outlook. The folder will be recreated but no contacts.

I have the same issue: my screen looks like the one above so I do not have the option to 'deselect'.

Is there another way to solve this?

PD.- I'm also using Outlook 2013, Lync 2013 client, Lync Server 2010

Hi Michael

I'm having the same frustrating issue with Lync contacts and have tried your suggests here but the Lync contacts folder cannot be deleted in Outlook 2013. Do you perhaps know how to go about deleting it?

My setup is as follows: Outlook 2013, Lync 2013 Client, Lync Server 2010

Many thanks in advance.

Is your Lync Server 2010 CU5 or higher? Did you run the powershell command: Set-CsClientPolicy global -EnableExchangeContactSync $False

Sign out of Lync and back in.

Delete the Lync contact folder in Outlook, if still having issues try to do this while the Lync client is not running.

Yes all Lync updates have been applied (using Windows Updates) and have successfully run the ps cmdlet however Outlook 2013 still does not allow me to delete the 'Lync Contacts' folder. I have also tried closing Lync & Outlook and given around 60 mins for any syncing.

I'll try the Lync 2010 Cumulative Server Update Installer tonight and report back, thanks for your help.

Hi, if you want to remove Lync Contacts whether duplicate entries, you can delete from OWA application, it just manually delete one-by-one Contact list or using Shift then sort.

In Outlook 2013 their can not delete because Read only method.

Regards,

I have tried deleting these manually, but there are thousands and no way that I see to delete them in bulk.

All you just need to do is 4 steps on the Lync server

1. Check what you have on -EnableExchangeContactSyc by doing c:\get-csuserclientpolicy. And make        is set to false by doing Set-CsClientPolicy global -EnableExchangeContactSync $False if you only have one policy but if you have another group policy apart from the global e.g. Accounting and you want to apply it to the group. Do c:\Set-CsClientPolicy -identity "accounting" -EnableExchangeContactSync $False

2. Do C:\Update-Csuserdatabase (this update client database)

3. Do C:\Update-CsAddressBook (this update client address book)

4. Do C:\Invoke-CsManagmentStoreReplication (this replicate changes to all Lync servers)

Give it five minute and all should be fine but some users might need to exit from Lync and sign in again to see changes.

All of these contacts have a note "This contact was added from Microsoft Lync 2010."

I searched for this note and removed all contacts with the note in them.

Not too bad...
