Draft folder is black, does not save an email draft, and has other folders in it?
My Mac does not save my drafts of emails for one of my gmail account because the folder seems to be messed up. As you can see in the attached picture, the draft folder icon is black and will not open anything. There are other folders in the Draft folder including one for Important emails. I do not know how they got there or how to remove them and fix my draft folder. I saved a draft thinking it was saved, but I cannot find any of the drafts I thought I saved. I don't know how my draft folder got corrupted but it no longer saves email drafts. I have several gmail accounts and all the others are working fine. Can anyone tell me how to fix this so Mail on my Mac will again save email drafts to the draft folder?
