I have 6 accounts on cox.net and today in two out of the 6 accounts, emails that I send are not saved and I get a message "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. The "sent" folders for these two accounts are grayed out. I have verified that the account settings have the right folder as the destination for the sent emails and have checked that all emails should be saved. I also get a message in Thundebird -The current command did not succeed. The mail server for account xxxxx responded [TRYCREATE} Mailbox doesn't exist. Mail goes out but no copy is saved. Only two out of 6 accounts are affected and I didn't do anything to them before this started happening.
