Why am I getting an error when attaching files in Outlook?

Question

"I am encountering an error when trying to attach files to an email in Outlook. Every time I attempt to attach a file, I either see an error message or the attachment doesn't go through. What could be causing this issue, and how can I resolve it? Are there any common reasons for this error, such as file size limits, connection problems, or issues with Outlook settings or updates?"

Hi @Mohit Pandey

Welcome to our forum!

Agree with @mukeshkumar korrapati . Attachment size may have an impact.

In addition, Outlook blocks certain types of files from being sent and received as attachments. For details about the types of blocking, please refer to:

Hello Mohit,

If you are attaching file more that 20 MB outlook won't accept. Send the file from onedrive. If it is less than 20 MB and still faing error try outlook web and check if you are faing any error. Let me know the result.
