Regarding the MS products on Mac - I have only installed Outlook for Mac because the web (Office 365) version of Outlook lacks most of the advanced functionality in the first place. I was hoping I will be able to apply a rule to existing emails (not only those that will come in future) or perform an action on batch of emails. In the end this is not possible on the Mac version either.
