How to clear Outlook 365 Mail Auto-Complete

Question

I have tried all recommendations:- File &gt; Options &gt; Mail &gt; "Empty Auto-Complete List"- Delete NR2 file: I don't have one- Edit Registry: I don't have the key&nbsp;It's a useful feature, but useless now as it's cluttered up with outdated emails.&nbsp; Thanks.

Have you tried closing Outlook, then opening it again with the switch below?&nbsp;Outlook.exe /CleanAutoCompleteCache

To confirm, are you using Outlook on the Web, or Outlook desktop?

Type ahead cache is stored server side now with exchange online. I found this article to clear it however not sure if there is a newer one since but it should give you a place to start. https://gallery.technet.microsoft.com/office/How-to-reset-OWA-auto-5b2b3d3b

That script appears to remove individual email addresses from AutoComplete.&nbsp; How do I remove ALL email addresses?
