With Satya Nadella at the helm, Microsoft seemed to have taken a markedly different path of late, co-operating with users and other vendors instead of using their installed base to destroy standardization efforts and crush competition.
I never use or install Microsoft Outlook on Microsoft Windows machines, not just because Outlook is a very weak mail client compared to free alternatives, but because the primary target for malware authors is a Microsoft Windows PC with Outlook, Office and Internet Explorer installed on it. If you use a different browser, and don’t have Outlook installed at all, you decrease the likelihood of contracting a zero-day infection (meaning malicious software for which there is no cure yet) significantly.
But Microsoft is up to their bundling and tying shenanigans again*… I’ve just discovered you need Excel to use the Group Policy Analyzer, and you can’t install Excel from the Office 365 pack without also installing the latest version of Outlook. Bundling their low performance, high cost, standards violating email client with the Excel software beloved of clerks and accountants everywhere.
For now I install Office 365, use Excel to receive the GPO analysis, export the tables, and then uninstall Office 365.
* also other shenanigans, apparently?
UPDATE: @fuzzyfungus points out that as an enterprise license holder I can use the deployment tool to install individual office components (although only after uninstalling the suite).
