On MacBook outlook or Mac mail, I cant create and new email folders

[Spud312R]

Over the last few months, i have noticed that outlook mail and mac mail on my macbook, that i can not create any new email sub folders.

I have to go onto yahoo web mail and create them there `and wait until tyhe macbook app sync's

It looks like its a Yahoo email issue that maybe they have stopped this function from working by using a non Yahoo mail client, should SKY get involved in this with Yahoo if this is the case ??

Maybe Yahoo are trying to force you to use Yahoo email client with ads or PAY for the non ad version ....

My account is an IMAP not POP

Has anybody had this issue ?
