Before modifying your desktop Outlook settings, ensure you have your synced mobile device handy, as mobile email settings often override desktop configurations and can cause hidden synchronization issues.

Solution 1Recommended

Unblock the Sender on Your Connected Mobile Device

If a contact is blocked on your synced mobile phone, it can cause emails to move to the Deleted Items folder across all Outlook platforms, even if the sender does not appear on your desktop blocked list.

A common but overlooked cause for this issue is mobile device synchronization. When a contact is accidentally blocked in the native email app on your smartphone, that command syncs to your Microsoft 365 or Outlook account, automatically deleting incoming messages from that sender.

1
Open the email on your phone

Launch the email application on your mobile device and navigate to the 'Deleted Items' or 'Trash' folder to find the affected message.

2
Access sender details

Tap on the message to open it, then tap the sender's name or email address located in the 'From' field at the top.

3
Unblock the contact

Look for the block/unblock options in the sender profile menu and select 'Unblock' to restore the contact's permissions.

Unblock the Sender on Your Connected Mobile Device
Synchronization Applied: Once unblocked on your phone, the synchronization will update your Outlook account, and new messages from this sender will stay in your desktop Inbox.

Frequently Asked Questions

Why do my emails go straight to the Deleted Items folder?

This usually happens due to background inbox rules, a sender being accidentally added to a block list on a synced mobile device, or the 'Ignore Conversation' feature being inadvertently activated in Outlook.

Will a blocked contact on my phone affect my desktop Outlook?

Yes. If your email account is synced to your smartphone, blocking a contact in the mobile device's email app will often cause emails from that sender to be automatically moved to Deleted Items across all devices, even if they don't appear in the desktop Outlook blocked list.

How do I check for hidden inbox rules in Outlook?

It is best to check rules via Outlook on the web, as it displays all server-level rules. Log in to your webmail, click the Settings gear icon, navigate to View all Outlook settings > Mail > Rules, and review the list for any rules that might be redirecting your messages.
