We have a Windows 2012 RDS environment with user profile disk configured.
We have a user who use Outlook in his RDS session. His Office 365 mailbox is only 3GB. There is a OST file in his profile disk which grows very fast in 24 hours to a size of 10GB. After that, his Outlook/RDP session becomes very sluggish and hung..
Anyidea of why this might happen?
