    Hi @Mustafa Guzel

    Welcome to our forum!

    For better research, please provide more details about this case:

    Does the problem occur in the Outlook desktop client?

    What type did you add to Outlook(POP/IMAP/Exchange)?

    Here are a few steps you can try to resolve this:

    Check Sync Settings: Ensure that your Outlook app is set to sync all emails.

    Update Outlook: Make sure both your Outlook app and web version are up to date. Sometimes, updates can fix sync issues.

    Check Filters and Rules: Ensure that there are no filters or rules set up in your Outlook that might be causing emails to be hidden or moved to different folders.
