I'm having issues when syncing my Mail.app with my Gmail account via IMAP. The loading icon will constantly be cycling next my Inbox with an exclamation mark stating: This issue occurred after I had trouble sending an email with an attachment exceeding the file size limit (40.5MB). Then, it started keep trying to sync the email even though the email is too large lending to errors. I removed and re-added the Gmail account and now this error is occurring. I am not sure what to do now, but any help is appreciated. Thanks.
