Hi,
my experience regarding the new 9.10 version is related to emails only.
The Inbound Email did work after I applied a hot fix.
The Outbound Email from system account works but all other outbound email accounts (personal and group) do not work because of authority denial.
The progress made in Email setup towards version 7.9.14 is not integrated in 7.10.0. This should be integrated and shall resolve a lot of issues.
From my point of view Email is very important and the actual functionality and comfort does not meet standards from other email clients. Users daily and often use Email and this part should be a brilliant tool. Messages pop up behind menu bars and no html designs are not nice. Even though I appreciate suitecrm.
Best
Werner
