We're trying to use Lync 2013 to talk to one of our satellite offices.
I can initiate a meeting with them and can share my desktop. However when they try to share their desktop they get the following error message: "An error occurred during the screen presentation"
I have found this article - http://www.ucfoc.us/2013/04/lync-2013-unable-to-share-screen-error.html - which suggests that the that problem could be down to one of two updates. We've checked and neither update is present on these machines.
These users are on a separate Office 365 tenant to us.
How do we rectify this issue?
