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
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
It's interesting this issue doesn't affect your gmail accounts. So far according to comments in this thread, it's a Yahoo and AOL email accounts problem.
I've been having the same problem. To take it a bit further, I've watched when it fails. It reports Synch errors for all the folders I have. It downloads, successfully, but appears to upload back to yahoo, and fails. I get the balloon, and the empty inbox, where it starts all over again. i have 10k email so takes about an hour to Synch and fail and repeat.
I've also followed the directions and removed the Outlook cache on my Mac. No change. Very frustrating.
No answer. My current thinking is remove yahoo from my outlook and maintaining my Yahoo mail using the Mac Yahoo App or from a browser or my phone. It kills my efficiency and organization of emails though and very annoyed with this. And Yahoo's mail sorting and other shortcomings are their own issue. Also, the constant re-syncing and reloading slows down my internet and other mail. Microsoft FIX THIS!!
I hear you.. I downloaded Airmail from the App Store and it synced all of my thousandssssss of emails associated with my yahoo account... Getting used to the Airmail interface, but no sync issues that have put me out of commission for a few days. I can't handle the yahoo email on the web browser. good luck... :-/
Just to let you know, I am having the EXACT SAME issues as you, David, with the exact same Outlook behaviors, on my 2017 3.8 GHz Quad-Core Intel Core i5 iMac, also after the 16.73 (23051401) update using the Legacy version of Outlook, only with AOL mail instead of Yahoo. I have re-entered the correct new app password generated from AOL, but all to no avail. I thought at first it was due to SpamSieve, but turning it off and then uninstalling both the app and the required Outlook Script files, reinstalling the same, etc., all is to no avail. I have had this account for over thirty years and am unwilling to part with it without a fight, but I also don't feel like migrating to Apple Mail right now either. Another example of Microsoft genius, sigh. With luck, someone is watching this forum and has a good workaround until the next update! Hang in there, everyone...
