After all these years, why is Outlook's "contacts" so BAD
For Exchange Online accounts, the suggestions are based on your internal relationships with your colleagues.
Signals are for instance what's been filled out in the "Reports To" field for your user and who else has the same value. This basically builds the Org Explorer.
Other signals are who you are in the same Microsoft Teams with and who you've recently communicated with in either Outlook or Microsoft Teams.
From my experience, the suggestions have become pretty good over the years when it comes to people I'm regularly in contact with or who are "close" to me within the organization. Obviously, when I want to contact a "random" person within the company, I need to type quite a bit of their name before it comes as a suggestion.
For POP3, these signals don't exist and it usually first comes up with people you've (recently) emailed before.
For completeness' sake, could you post your exact Channel, Version and Build number as reported in;
File-> Office Account
I guess when I'm in the corporate account, and it;s a big corportion, it's no surprise I've never heard of most of the names it pops up - but really I'd rather not see them, and just see names I've had contact with.
Another thing is, it's so inconsistent. With the same prompt (first few letters typed) I get a different set of choices every time. And something else, for eg: there is one, and only one, address that begins with the letter u that I email on occassion. That never - ever - shows up. I always have to type the whole thing, ignoring the irrelevant options I am presented with.
