IMAP mailbox listing error
Speaking Email supports an IMAP account type, and also uses secure IMAP to access most cloud providers (Outlook.com/Hotmail, Yahoo, AOL, iCloud).
This error is shown when your login to the IMAP server was successful but an error was returned when we try to read the contents of the mailbox. This is an unusual situation and may indicate a problem with your mailbox.
- Your mailbox may be busy or be restricting access due to too much activity. Wait a while and try again.
- Duplicate folders - if you try to access Exchange server via IMAP it will not allow any duplicate folders. These are allowed in Outlook and OWA (Outlook Web Access) so you can use these to find and delete any duplicate folders.
No such mailbox, can't access mailbox, or cannot find Inbox.
Try accessing your mailbox using IMAP from another mail client or use Microsoft's Connection Tester.
