Outlook 2016 setup - cannot create pst file the path is too long

Hello!
I am getting the following error when trying to setup an active sync (file -> Account settings -> manage profile -> email accounts -> New -> manual setup or additional server types -> Next -> exchange active sync) account in outlook 2016, is there anything I can do to fix this?

I am using the latest zextras version (2.6.7) on zimbra 8.5.0, also worth noting that setup works fine in outlook 2013 as well as mobile devices, the only issue is outlook 2016 it seems.
