I have been using Outlook for years as the "no bullshit" client for all the accounts I have and the biggest feature that has been missing for me is the ability to link to individual messages or threads, so I can just store links to these messages in my notes and plans instead of having to search for these messages each time. Weird that this is not mentioned as an important feature.
