Length of time for keeping emails in In Box
I keep certain emails in my In Box that I prefer to keep for more than 6 months and they disappear. I cannot find them. Only one month at time will be retained in my In Box for some reason. I want the option to choose how long to remain in IN BOX.
Emails will not disappear as long as the account is active.
If you are noticing that emails are being deleted this could be due to how the account is being accessed outside of yahoo.com or the Yahoo App.
We see this when a 3rd party email client such as Outlook or a stock mobile app is being used.
