Duplicated Lync contacts in Outlook (Lync 2010, Lync 2013, Outlook 2010, Outlook 2013)

-
This is an well-known bug in Lync with Exchange/ Outlook.
 
It seems like, the Lync-Outlook connection is somehow bouncing.

There are several solution, based on your Lync environment, but independent from the Outlook version.




First with Lync 2010 Client:


You need to start navigating to the Client OPTIONS and uncheck under contact the "Save my Lync contacts in my personal contacts folder on the Exchange server check box"




If you have Lync 2013 (15.0.4517.1005 or newer) or Lync 2010 (4.0.7577.4419 or newer) installed there is only one other option.
Lync 2013 Client Update May 2014: http://support.microsoft.com/kb/2880980

- Lync Server 2010
  Upgrade your system with CU5

- Lync Server 2010 CU 5 and Lync 2013 (any CU)

You must change your Lync Client Policy

Set-CsClientPolicy -Identity Global -EnableExchangeContactSync $False

another option is, since not all clients are affected, you build another ClientPolicy with this option disabled.

New-CsClientPolicy -Identity OutlookContact -EnableExchangeContactSync $False




Deleting the Contacts:

After you have changed this setting and they are applied to the user, he is able to delete the duplicated contact in Outlook.
If you still facing problems deleting the contact, go to Outlook Web Apps and delete them in a browser.

      Hi Luis,
      since I'm not the ultimate Office365 guru. But in Office 365 are not Client Policies with in-band provisioning.
      You should be able to find this settings in the Office ADMs (Templates) and restrict the same.
      As info, Client Policies in in-band provisioning will always overwrite office template/ registry settings

How to hide users from GAL if they are AD Connect synchronized

How to hide and un-hide users from Global Address List (GAL) in Exchange Online if they are AD Connect synchronized Hiding User from GAL isn't possible if those are synchronized form On-Premises Active Directory. The local AD is the leading system for all important attributes, like SMTP, UPN and hiding from GAL. Especially during a cross-tenant migration, you do not want to see not migrated user in the GAL. Those User aren't actively working until their cut-over day. Since the Exchange Online attribute  msExchHideFromAddressList s is an AD on-premises parameter, we have two possible ways hiding user in BME from GAL.   Modify the AD Connect for your teant with a custom rule, by using a extensionAttribute to set the HidefromGAL. In this rule, for users which have an entry in the extensionAttribute, hiding / un-hiding will be controlled by AD Connect This is the best option for Cross-Tenant Migration, if you run 2 or more AD Connect system We direct modify the AD hide at

Lync Edge Server FQDN and IP PORTS (Version 1.2, Update 26.11.2014) As we all know, we can configure Lync Edge Server in several way. 1) Single Edge Server with a SINGLE IP ADDRESS 2) Single Edge Server with MULTIPLE IP ADDRESSES (3x IPs) 3) Multiple Edge Server in a Pool, with MULTIPLE IP ADDRESSES (Zx 3 IPs) Regardless what we are going to configure, there are common / well-known TCP Port necessary making Lync work, which are: Access: Port: 443 and 5061 Conferencing: Port: 443 and (444) AV: Port: 443 (I have not listed other ports, e.g. STUN or the dynamic port range. This is not required for the topic discussed here) External FQDN with single IP address: What can we see here? If we are going to choose a single IP address, we would have TCP Port overlapping. Therefore the only way avoiding this is assigning other ports. Additionally we will also see and are reminded that Lync highly depends on DNS. If we have single IP, we must have use single, unique FQDN fo

There is an update regarding MFA Multi Factor Authentication. If you are guest with a different Tenant, the MFA Settings are now reflecting the settings of all tenants in a different way.
