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.
Using older versions of Outlook for Mac in business environments

Hallo again Sudhanshu,
Just wondering if your computer has an Intel or the latest Mac silicone and what version of macOS you are running. Perhaps thats the reason the port change does not work in all cases.
Fix didn't work for me either. Best bet is to use the Mac Mail app to manage emails. The accounts are already set up in System Preferences, just need to toggle the mail on . It syncs fine with Yahoo, which allows the one-way sync to work with outlook should you choose to keep using it.
Hallo Sudhanshu,
Thanks for the heads-up. Better than MS!
Reading the posts this seems to work for some. Did not work for me. I will try again and maybe reinstall Outlook (again!) and see if it makes a difference.
Best Regards ........ Ronnie
switching to the 587 port has not resolved for problem for me. The Create Folder errors stopped, but the server reloads continue and the sync only works one-way: Yahoo to Outlook.
This might be useful...
https://sendgrid.com/en-us/blog/whats-the-difference-between-ports-465-and-587
Outlook on mac by default uses port 25 without SSL and port 465 with SSL for outgoing server.
Gmail seems to be working fine with these default port configuration but for Yahoo, looks like it prefers 587 for SSL.
Still trying to connect dots for the problematic behaviour and its resolution with port change to 587.

Sudhanshu
