By default if your Lync SIP address doesn't match your primary SMTP email address, then Outlook integration will not work. You can resolve this by disabling the client policy DisableEmailComparisonCheck using the following PowerShell command.
Set-CsClientPolicy -DisableEmailComparisonCheck $true
Hi,
ReplyDeleteThanks for the post! I was looking for a solution regarding this issue. You just saved hours of troubleshooting!

Glad it helped!
ReplyDeleteWhat are the consequences then? Does the Outlook integration simple not work, or does the system simply use other methods to discover the mailbox, thus increasing the time or load on other Lync components? I've just worked with some messed up environments where it's a mixed bag, some are "correctly" setup, others are not.
ReplyDeleteYou need to set this to allow mismatching email and sip domains, however in my experience its pretty volatile and some things will work in some environments and not others. This post may help you out further - http://www.lync.geek.nz/2014/04/lync-2013-exchange-integration.html
