I've had a Cox email address and account for roughly 20 years.
But over the last several months my older emails have started disappearing, everything before a given date. Initially I lost all emails in my inbox from about two months back, then about one month previous, and now everything before one to two weeks back! (Today is Sept 24 and all my emails before Sept 12 have been deleted.)
I primarily use two IMAP email clients, Mac Outlook and Mac Airmail 3. The lost Cox emails are automatically reflected in both email clients. If I move an email to another folder or star/flag it, it remains accessible, but if I don't act on it in time, it is soon lost. This is very frustrating, as several critical emails I needed to access have vanished into the ether.
I have only used 185 MB of my allotted 2 GB, so I'm not close to approaching my quota. I can find nothing in settings or elsewhere to change this action. This problem has occurred similarly in both the old and new Cox email formats.
Hope someone can help. Thanks!
