Per GoDaddy: IMAP is NOT reliable with sent folders in Outlook and other email clients
One of my e-mails inexplicably vanished from my Outlook Sent folder immediately after sending it, and GoDaddy was NOT able to recover it. GoDaddy explained that IMAP is reliable only relative to the Outlook inbox, and is NOT reliable relative to any of the other folders in Outlook or other email client applications. (And then they offered to upsell me to their expensive Microsoft Exchange service.) Therefore, anyone using an e-mail client with GoDaddy's IMAP may have their e-mails disappear, as happened to me (and they cannot be recovered).
If anyone can recommend an e-mail client that is reliable with IMAP -- across all the folders -- I would appreciate that.
