Missing Email Folders in Transition to Yahoo Email

there is no phone support for yahoo , good luck with their cumbersome help system

After a long conversation with a Yahoo rep, I was able to find my missing folder!  It may have taken awhile to migrate, but it's there now.

@user_jm3y1​ How did you locate the Yahoo rep. All of my folders are missing. 

they provide no support. it really stinks since they forced this migration,

you would think that the would supply a minimum of support.

I have solved the problem. You could have made this Yahoo  migration much easier. When I called Xfinity help, he gave me the website of the 20,000 pages of Yahoo help, no phone, no chat, no email.

Thank you for the offer of help. But I was able to figure out the problem myself

I am very sorry the process was not easy. I am glad your concern was resolved. We are here to help if you need us!

I guess I should have shared this solution, because maybe other people can use it to solve their folder problem. My folders are missing on the Yahoo website. But on my Outlook client on the phone they were there. So I knew the folders were on the server. I looked around and looked at some documentation and it turned out that I just needed to widen the left panel of the Yahoo mail interface on the web and then narrow it again and voila, there were the folders. You have to be very sensitive because it's kind of like a very dim double arrow and you have to click it right on the border. This is Insanity.
