E Mails more than 14 days have disappeared from the Inbox
I have been using a BTinternet.com mail account for many years. We have kept general old e mails in the inbox, copying a few into specific folders. My inbox is fed into Outlook using IMAP. I noticed today that Outlook was only showing 14 days history. I assumed initially it was a filter through to Outlook however I have now gone into my bt mail account through my bt and when I check the e mail on the web server only the past 14 days is available.
What has happened to the history and how do I restore it.
Interestingly the Outlook e mail and the web browser on mybt still has old e mails which had been saved in specific folders
