I had some issues with webmail on Wednesday with error messages. Since then, my inbox has ended up with -1 unread emails. I've tried a couple of bits including marking everything as read/unread, moving out the emails from the inbox and then moving back, checking the folders for rogue emails. However, no luck with any of this.
BT email app is fine as is via Thunderbird. I am still having some issues with errors related to emails loading and also downloading attachments when the email is the first one in the inbox.
Any ideas?
