Low disk space - C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Temp

Hi all,

I'm running Exchange 2013 Version 15.0 ‎(Build 847.32)

The following directory is 30GB in size and is growing: c:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\data\Temp

Is it safe to delete these temp files?

Thank you
