Redirect incoming emails on my iPhone

This is usually caused by a rule or mailbox setting rather than the iPhone itself.

Try these checks in order:

1. Check Outlook on the web first
   • Sign in to Outlook on the web in a browser.
   • Check Inbox, Junk Email, Deleted Items, Archive, and Conversation History.
   • Make sure the inbox filter is set to All.
   • If Focused Inbox is enabled, check the Other tab too.
2. Check for rules that move mail
   • In Outlook on the web, go to Settings > Mail > Rules.
   • Look for any rule that moves messages to Conversation History or another folder.
   • Disable or delete any rule like that, then send a test email.
3. Check forwarding
   • In Outlook on the web, go to Settings > Mail > Forwarding.
   • Make sure mail is not being forwarded unexpectedly.
4. If a conversation was ignored, restore it
   • Open the Deleted folder.
   • Select the affected conversation.
   • Open the ... menu and select Restore Conversation.
5. If using Outlook for iPhone, review conversation display
   • In Outlook for iOS, open the message list.
   • Tap the mail icon in the upper-right corner, then tap Settings.
   • Go to Mail > Email Organization.
   • Turn Group emails by conversation Off.
   • This changes how messages are shown in the list so messages appear individually.
6. Check Focused Inbox
   • In Outlook for iOS, go to Settings > Mail.
   • Turn Focused Inbox off temporarily so all messages appear in one list.

If messages are still being delivered into Conversation History, the most common supported cause is an Outlook rule moving them there.
