I have Comcast as my ISP. It is an IMAP account. When I changed over I created a mailbox on their server for EMAILs I have read but didn't want to delete. Until last week I had no problem seeing this mailbox on macOs Sierra mail. Then all of a sudden I can't see the mailbox.
I can see the mailbox on my iOS devices, iPhone 7 and iPad Pro 9.7. I also can see the mailbox in Outlook for MAC. Everything I tried, deleting and recreating the mailbox on the Comcast site, deleting and recreating the mailbox on my iOS devices and deleting the mail box on the Comcast site and recreating it in macOs Sierra Mail does not help.
Any Ideas?
