I'm getting random "U0050014 Cannot open attachment file '<some UNC path>', error code: '121', error description: 'The semaphore timeout period has expired.'. " Errors when sending files as attachment. I'm on v10 preparing to upgrade to v12.1 and this occured after migrating an engine from an older Windows OS to a MS Server 2016. Anyone experience this before?
