Incoming email goes directly to Trash folder

Use the following checks to resolve incoming mail going to Trash instead of Inbox:

1. Check for rules in Outlook and on the mail server
   • In Outlook for Windows, review all Rules (including client-only rules) to see if any move messages to Trash/Deleted Items or another folder. Disable or delete any suspicious rule.
   • If the account is with an ISP or webmail provider (for example, AT&T, Comcast, etc.), sign in to the provider’s webmail interface and check its filter/rule settings. Some providers apply server-side filters before Outlook sees the mail. Remove any rule that moves messages to Trash or deletes them.
   • This scenario matches a resolved case where an AT&T webmail filter was silently moving all messages to Trash until the filter was removed.
2. Check Junk/Spam settings on connected devices
   • If the mailbox is also configured on a mobile device (for example, a Samsung phone using the default mail app), open the mail app’s settings and review any Spam or Blocked/Spam addresses lists.
   • Remove any entries that should not be treated as spam (for example, the entire corporate domain or own address). Misconfigured spam settings on a mobile device can cause messages to be moved to Junk/Unwanted/Trash folders even when Outlook itself has no rules.
3. Verify Outlook features that move or delete messages
   • In Outlook, check that the Ignore feature has not been applied to important conversations. When a conversation is ignored, all future messages in that thread are automatically moved to Deleted Items instead of Inbox.
   • If a thread is being ignored, stop ignoring it so new messages in that conversation stay in the Inbox.
4. Confirm no hidden or unusual folders are being used
   • In some cases, rules or server-side filters can move messages to folders such as RSS Feeds or custom folders that are then auto-deleted. Review folder list and any special folders (RSS, Archive, etc.) to ensure no rule is diverting mail there.
5. If the issue persists
   • After removing any problematic server-side filters, mobile spam settings, and Outlook rules, restart Outlook and send test messages from multiple senders.
   • If messages still go to Trash, use the mail provider’s webmail to see where new messages arrive. If they appear in Trash there as well, the problem is still on the server side and must be fixed in the provider’s webmail settings or by their support.
