Emails Being Returned With Error Code

Hi there,

I’m writing to see if someone can help me. Our business emails are being returned with the error code below for the past few weeks and I’m at a loss as to how I can fix it. If anyone can help it would be greatly apprecitated.

Best Regards,

That sure looks like your mail host has a limit you exceeded. I suggest you contact them.

Have you tried looking for an issue regarding the official Microsoft help/support page?:
