Mac/Outlook/SecureAnywhere

We just got our first client that has more than 1 or 2 Macs.  We put SecureAnywhere on 14 of them, and since then, multiple Mac users report that their Outlook freezes several times a day, and they have to force quit and reboot their machine.
 
Some of these users have very large mailboxes in 365.  The user who called it in her mailbox is 49 Gig.  I figured that it might be hanging when webroot is scanning the offline cache file, so I went to create an Override for the path ~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles, but when I click Path/File to install the Overide, it says endpoints must be running version 9.0.1 or higher.  The Mac agents that I just downloaded 2 weeks ago are version 8.0.10.18.
 
So #1, is there any wasy for me to exclude the Outlook cache folder on a Mac, or #2, is there any other known issue that I did not find with a search that might be going on here?
 
Thanks ahead,
