Increase number of contacts in Lync 2010 and Lync 2013?
Recently users where complaining to helpdesk about unable to add contact on Lync client. This is common scenarios where user unable to add contact and then Administrator will check client and later Lync server setting.
After looking on server found that Maximum contact limit is 250 setup globally in our organization. Affected user added multiple nested Distribution list on their Lync client.
You can use below command let to get the contact limit.
Get-CsUserServicesConfiguration
If you want to increase or decrease number of contact to all user or group of user you can using different command let?
In my case I need to increase Lync number contact size to 500 contact for all user who has Lync access.
Set-CsUserServicesConfiguration -Identity "global" -MaxContacts 500
Above command will set server configuration too globally to contact size 500.
If you want decrease contact size then go to Lync Power shell and run below command.
Set-CsUserServicesConfiguration -Identity "Global" -MaxContacts "250"
Now you can see Get-CsUserServicesConfigurationto see the current contact limit.
Thank you.
