If you are still on Outlook Mac 2011 then this article explains the new features in detail. However at high level the best improvements are:
– Speed thanks to the new database engine which also makes archiving large batchs of mail a lot quicker through out tool
– More accurate and faster search.
– Better network stability and faster synchronisation to server

If you do install/upgrade it is possible to run Outlook 2011 side by side with the new Office 365 version (ver 15.x). This is a common scenario if you wish to import your 2011 accounts in to the new Outlook. Our Outlook Mac Archive Tool (OMAT) does not support archiving from both Outlooks simultaneously and there are important issues to understand while you have them both installed:

– OMAT makes heavy use of the Outlook scripting interface. When Outlook is not running, if you run our tool manually or by schedule then it will automatically open the ‘last opened’ Outlook to perform the archiving.
– If you have one of the Outlooks open and running our tool will attach to that Outlook and attempt the archive on that version.
– If you have your email accounts setup in both with the same name then it will archive in the active Outlook and not the other. If you have different account descriptions it will fail to archive as the account name stored in it’s profile settings will not match.

Given all these conditions we recommend not running our tool while you have both installed. Complete your account migration and then re-enable our tool on the latest version of Outlook.

If it’s essential to keep archiving during your transition then given the above conditions we recommend you only manually run our tool with the version of Outlook open that you want it to run against and have the profile settings appropriately configured for its account setup.
