Right now, file transfers are either enabled or disabled. But some org security groups have heartburn over files leaving the corp network, or going to federated contacts due to data leakage. A policy option to limit file transfers to just internal endpoints, or just org users, would be nice
Would like to see a Lync Report for File Transfers which includes information on the file that was transfer, including name, date, size. Currently all I can see in L2013 reports is who sent a file to whom, with no additional info.
Right now, when you create the mirror, you specify a temp file share for it to copy files to. It would be nice if it cleaned up those files when it was done with them.
