We will be upgrading exchange 2013 in our organisation to CU15.
I would like to determine if any of the integration between lync 2013 and exchange will be affected by this upgrade.
I have read that OWA integration of lync might need to reset after the change via the backup of web.config file.
But we do not use OWA in the organisation.
Is there anything else I need to check from Lync perspective before going ahead with CU install.
