I’m having the same issue–slow insider track updates to Outlook (Microsoft 365 subscription through work ver. 16.41 (20091202), but I’ve never clicked on the “New” Outlook toggle.
New messages have stopped being moved from InboxSpamSieve (started with the slow insider update before this one). SpamSieve still works fine with Apple Mail.
Using OS 10.14.6.
Thanks for any advice or a fix?
