Cannot Synchronize Yahoo Business Account Inbox

[mickkev]

I cannot synchronize Yahoo Business account inbox.  Every time I try it, a message that reads "Error Synchronizing Mail: Invalid server response."  I do not have this problem synchronizing other folders  (e.g., Sent, etc.) of this account or other accounts such as Yahoo, Gmail, and Outlook.  Can someone help me?  This problem happens to all of my Android devices. 

By the way, I installed other email apps such as Yahoo Mail app.  They do not have this problem.

Yahoo often breaks something on their side.

If you'd like me to investigate, please capture the issue in the app's debug log with "raw session data" enabled, please see the link in my signature below.

It seems that lately Yahoo support has been better than before at fixing various issues (I've had two users lately who let me know the outcome).

As for other apps --

The definition of a "working email server" is not "works with app X" or "works with app Y".

There are many ways a mail app can interact with a mail server, and as long as that's within the formal definitions of what's valid -- it should be all fine. And then you've got other accounts in AquaMail as you've noted...

Thank you!  I will wait to see if Yahoo can fix this on its side.
