Errors in mail account and IMAP settings

Errors in mail account and IMAP settings

Hi, I recently removed my organization in Zoho control panel. As a result, my personal email's mail account, IMAP and forwarding settings stopped working with "Oops! We were unable to retrieve your accounts details. Try again later."
Is there anything for me to do? Also, is IMAP still available for my old account on the Free Plan? Thank you.
