    Hi @Tyler Lam

    Welcome to our forum!

    Did you try to send emails with PDF attachments?

    If so, I'm afraid this is related to a temporary backend issue. Microsoft has taken note of it and is looking into it. Sorry for the inconvenience, please be patient and wait for this issue to be fixed and i will update here as soon as possible. Thank you for your understanding and support!

    In addition, I found a thread mentioned that it's useful to change email format, as shown in the below image. It's suggested that you could try the workaround.

    (In order to avoid the privacy leakage, I have hidden your emails address. Please remember to hide your personal information before your post.)
