please fix it ASAP, that monstrous quick delete button malfunctions, and takes a lot of space, which can be used much better! It is worth of some freeware solution, not serious office mail client!
please add possibility to include more mailboxes, offline and online archives to search folders function, currently only subfolders from one mailbox can be selected for search folder. this will help a lot people using categorization of mails to effectively build custom views.
I am very sad, that after all previous versions, also Outlook 2016 did not fix the dialogue window:
Attach Item > Outlook item , which is very small and even does not allow size adjustments. It is very unconvenient to search for a message, which I want to attach, in such a small window, adding some search would be great as well...
