Folders Limit


New Email
I have a Premium Account at
I was transferring my Outlook emails on IMAP.
Doing this I created Folders.
Now I get an error message every time I try to create a new folder: "Folders quota reached".
I have try in Web or different Mail App, Os, computer and networks and I am still having the problem.
I sent a support request. They confirm there is no quota or limits even for folders and are investigating my case !
Do You any idea ?
