After update to 16.73 Outlook for Mac, Yahoo mail keeps re-syncing and reloading. Changes made in Outlook AND Yahoo are not syncing.

Prior to this update, I had no issue with Outlook for Mac and Yahoo. I just updated to 16.73 (23051401). After updating, I had many problems with the Yahoo mail from within Outlook. It worked for the first 15 minutes, then got login errors and IMAP errors. I deleted the Yahoo account from Outlook and then quit. I then went back to Yahoo and got a new app password. I restarted Outlook and added the new app password obtained from Yahoo. It worked for the first 15 minutes then started to suddenly empty out all emails in all folders. Then the emails would eventually re-sync and reload from Yahoo. This now happens constantly. I tried the same uninstall reinstall process again, and nothing changed. Now also changes I make within Yahoo via my browser are not reflected in Outlook and changes made to Yahoo mail within Outlook are not saved when the emails clear, res-sync and reload, and they are not reflected in Yahoo online either. It's stuck in a loop. New emails DO ARRIVE and get added to the loop. Also there is a constant attempt to recreate the basic Yahoo folders: Drafts, Archive, Junk, Bulk. I get error messages saying can't be installed because they already exist - which they do! Why is it trying to reinstall them as if it is a new connection with Yahoo?

My setup is the following using OUTLOOK for MAC - BUT NOT NEW OUTLOOK. New Outlook does not support all the folders I have created over the years for organization and am unwilling to lose. I have a 16 inch MBPro M1 Max chip. Running Monterey 12.6.5.

AS a side note, I have for the past year or more had problems where white-listing emails does not work. Outlook is putting emails of people I email with regularly into SPAM. I whitelisted many of them, but Outlook is ignoring the classification and still putting those emails into SPAM.

    Microsoft recently released (Mar. 2023?) FREE Outlook for the Mac. It is a native standalone app in that it does not need Office 365.  It supports local – on my computer files – and you can switch to the legacy Outlook if desired.

    See it here > https://techcommunity.microsoft.com/t5/outlook-blog/outlook-mac-for-all/ba-p/3757787#:~:text=Outlook%20for%20Mac%20is%20now%20free%20to%20use&text=Whether%20at%20home%2C%20work%20or,and%20calendar%20app%20on%20macOS.

    My question – has anyone tried the new Free Outlook and was the switchover from Outlook 365 for the Mac easy?  More importantly did it solve the problem we all have encountered? Thanks.

    You can switch back from the Outlook menu - New Outlook entry on the menu is a toggle.

    General information about new Outlook and screenshots-

    The new Outlook for Mac - Microsoft Support

    From

    Set preferences for Outlook for Mac - Deploy Office | Microsoft Learn

    Most preferences can be changed using the Terminal, or via a script.

    One of these commands should block it, hopefully even for updates -

    defaults write com.microsoft.Outlook EnableNewOutlook -Integer 0

defaults write com.microsoft.Outlook EnableNewOutlook -Integer 1
    Category Details
    Domain com.microsoft.Outlook
    Key EnableNewOutlook
    Data Type Integer
    Possible values 0 = Switch hidden <br>1 = Switch displayed, default off <br>2 = Switch displayed, default on (default) <br>3 = New Outlook enabled with switch hidden

    Having the same issue on Macbook M1 with Big Sur and outlook.

    Decided to try my old work macbook that has been sitting on the shelf for 2 years with Outlook 16.54 and BigSur.

    And it had the disappearing inbox issue everytime I delete an email.

    So if the problem appeared now on a computer that worked 2 years ago then it must be in the server end. The blame passing is awful. Microsoft if your program doesn't work you figure out how to work with everyone else to make it work. We pay for a subscription for ongoing support and you should know how to fix it better than us.

    If Yahoo made a change that affected the older versions, it's not Microsoft's fault... but it will take time for Microsoft to figure out what is causing it and to fix it.

    Yahoo did make some changes to the server around the same time as the 16.73 update, so its not Outlook at fault.

    Perhaps, however I've also been using Mac's Mail app and it has not had any of the sync issues that I've experienced with Outlook.

    I'm hoping that Microsoft works to address the issue...otherwise I'll have to go back the Mac's Mail and Calendar apps. Would be a shame because I like the look/feel of Outlook.
