hello, in the previous version of outlook office365, it happend that when using re-occurent mailadresses together in seperate mails, the adresses where somehow linked together. So after sending three or four mails to the same group of mailadresses it was only required to start typing one of the mailadresses and you would get the option to select them all together out of the dropdown. Now in the latest version this seems no longer possible.

Is this related to a setting or is it just on of these features that get lost as development continues?
