Yes. Our policy is to automatically delete messages in your “Trash” or “Spam” folders that are more than 15 days old. Removing these messages will help you avoid wasting storage space on unwanted data, but still provide ample opportunity to review and relocate any accidentally or erroneously filed messages.
Automatic removal only operates “Trash” (Deleted Items) and “Spam” (Junk). You can still use your main Inbox and any other folders to store messages as long as you like.
If you are using POP3 style access, you download your mail into your Local Folders inside a mail program like Outlook. Since those Local Folders are stored on your computer and not on our servers, those emails on your own computer are not affected by our automatic purges.
