Updates on the new Outlook for Windows

Looks like there will be a very large part of the office userbase who will not be continuing the subscriptions to the ongoing upgrades of versions of Office licence versions (forced acceptance after 6 months?) and then maybe sandboxed Windows environments when security updates become unavailable.

I have a sandbox setup for Excel 2010 to deal with the changed/discontinued features, and basic facilities in the 2016/365.

Surprising thing is how much faster opening the 2010 version, loading files and processing is in that version -

with the added ability to deal with large workbooks containing complex formulas for data validation, and projections in only 4GB of RAM, as well as CF's and large data copy/paste actions without just (apparently, - well I'm not sure Excel actually stopped rather than sitting waiting for the OS to give it some more resources) stopping processing of the workbook.

I suspect the speed is partly associated with a MS design requirement to the coders restructure of the distribution of data and code into different modules (files).

as in a separate file to load for each action to deal with user interaction -

Error detection, handler load, message set (data file) output composer, output handler, display (panel)calling, user input detection, user input string assembly into passable variable, get the response handling code to pass the message, disconnect from the display panel, close the panel handler, and .... then reload the Excel base module that is now on the Pagefile!

But that's just the impression I get from the Resource monitoring software on 2010, and 365.

Not allowed to have data mixed in with code anymore - security concerns ?
