Hi hoping someone can help, I have sent and email to someone I have emailed in the past this time in a reply, I have since had an email sent back to my junk from p*********@outlook.com saying that this could not be sent as It was too large to send. All seems rather suspicious, not sure if this is just a spam email although does contain the intended recipients email. Not sure what to do.

    Dear William6379

    Thank you for posting in the Microsoft Community.

    I understand your situation and needs. First of all, this postmaster email is not a spam or phishing email. It is an official Microsoft Unable to Send Mail error report. You can refer this link to know about it.

    Failed delivery messages from the postmaster at outlook.com, microsoft.com, or service.microsoft.com - Microsoft Support

    Outlook has a send size limit of 25MB. you can check if you are sending an email that exceeds the size limit and cannot be sent. You can refer to this link for outlook sending restrictions.

    I hope that my reply will be helpful to you.

    Please feel free to let me know if you have any further updates, thank you.
