Outlook 365 Inbox not updating
Yosef Fridman .. I had the same issue. Turns out all I had to do was Reset the View. (Pity I'd already gone down the rabbit hole trying new profiles, etc. Oh well!)
Just putting this up here to save others some time, I hope.
What ended up working for me was none of these solutions (I tried them all), but rather running the Outlook tool which is part of the Microsoft Support and Recovery Assistant. There are about 10 different issues it diagnoses and solves with Outlook, one of which is problems receiving/sending email.
If it matters, I am a business Outlook 365 user; some documentation implies it only works with business users - but you might as well try it if none of the other solutions presented here work. The page itself lists "Microsoft 365 for home" as one of the supported environments, along with Office 2019, Office 2016, Office for business, Office 365 Small Business Admin, Office 2010, and Office 2013.
