Good Morning -
We have a RED 10 device setup in Standard/Split mode connected to a UTM 9.312-8. This week we updated a couple clients from Outlook OWA to the Outlook 2013 office application. Outlook is connecting to a hosted exchange server. Users at the main office (behind the SG135) have been using the Outlook 2013 office application without issue for over 6 months. The two users who are in the remote office behind the RED 10 are having issues staying connected. After launching Outlook 2013 it will connect and function correctly for about 10 minutes. Then outlook will lock up with a message about trying to connect to Microsoft exchange. At first we troubleshooted this issue under the assumption that we had an issue with outlook and our hosted exchange. Finally for testing purposes, we took both clients off of the RED and put them on a separate stand alone firewall and they no longer are having an issue. This tells me that the issue has something to do with the RED 10 device and the SG135 UTM. Does anyone have an idea on where to start to help resolve this issue?
