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

So after reading all the posts that New Outlook was supposed to work, I bit the bullet on Saturday and switched over. I added my AOL account and was presented with the option to either use Microsoft Cloud sync or stick with IMAP. I don't think Microsoft needs to store all my data since it's already being hosted on AOL's servers and didn't need to be in 2 places, so I opted to use the IMAP option instead. It took a good part of Saturday to sync up all my subfolders in my AOL inbox and in many cases I had to actually click the individual folder and tell it to sync and wait for them to populate. This went on for most of Sunday too. (I have a lot of subfolders and some contain several years' worth of messages.) So I thought everything was working fine. Then late on Sunday evening I quit Outlook and when I reopened it later, many of the folders I had populated were empty again and I had to to sit and wait for the data to sync. Is this the New Outlook's behavior if I don't allow it to sync to Microsoft Cloud? I would think that once a folder syncs it should stay synched, but this is not my experience at this time. Has anyone else who has switched to New Outlook, tried closing the app and reopening to see if the syncing holds, or am I missing something?

Appreciate the update!

I believe I'll give the "new" Outlook a try later today. I REALLY don't like the way I tense up now every time I open old Outlook and go from offline to online, lol. Not healthy!

Update time: been using the New Outlook now over a day and have had absolutely no glitches, belches from Yahoo or anything else. Everything works quite smoothly and the only negative I have found is moving folders, via drag & drop, is crippled. Otherwise, there are many new likeable/improved features such as contacts, message composing, etc.

The Settings are more robust and it takes a little time to learn all the changed screen navigation points so there is a slight learning curve.  For me, clearly the New Outlook is much better than the Legacy version and at this point I have no intention of going back.  Having said that I won’t unravel the folder structure I created to work around the Outlook/Yahoo beast just yet to be on the safe side.

Finally, I still don’t trust M$ because this was preventable and there was almost zero support and that was as dismal at it comes (typical for M$).  I’m still convinced M$ rocked everyone’s boat to push us overboard into the New Outlook.

Okay, RetiredGeek ... I'm gonna hold off trying to move my Exchange email to Apple Mail (I've encountered some issues) and will wait to see if you report back with continued success with "new" Outlook.

Hi Diane ... I actually don't need the On My Computer feature - I seem to be one of the few who never used it. My concern continues to be the constant emptying of random folders in Outlook during syncs with my Yahoo account. I'm a little gun shy at the moment, so I'm sitting tight to see if others are able to stabilize their situations with "new" Outlook. If it looks like the situation has been resolved via new Outlook, I'll probably make the switch to it rather than start over at my advanced age with Apple Mail.

Thank goodness I found this thread!I have been experiencing all the issues posted here for at least 2 months. If I had a dollar for every hour I've gone around and around with ATT because my passwords for my four accounts were continually being rejected, I could take a really nice vacation:) ATT kept telling me it was because someone was trying to break into my accounts. I knew that was highly unlikely since I use a pretty complicated password program, plus it continued to let me enter the "old" password! It did't occur to me that Microsoft was the problem until an entire Inbox would disappear & then reappear. or emails would reappear in the my Junk folder quicker than I could delete them! I had switched to the "new" outlook when I did the last update, but quickly changed back when all my folders accumulated over 2 decades disappeared too. When I switched to a Mac years ago, I tried Apple Mail, but found moving all my saved folders unsuccessful. Apple mail wasn't working, so I switched to Outlook for Mac. I'm encouraged by the solutions some of you have found and am going to give them a try after I can get my mail boxes cleared some on Yahoo. Thanks to all of you have given me hope for a return to mailbox sanity!
