Hello,

This usually happens when you send emails through Outlook and the recipient’s server flags the message as suspicious. Possible reasons include the type of attachment, the format of the email content, or the message being blocked as spam.

Make sure the body of the email does not contain spam-like phrases or too many links.

You can use online spam testing tools such as: https://glockapps.com/
