"Recipient server did not accept our requests" error
You'll see this error message if Gmail isn't able to connect to the email server of your email's recipient.
What to do if you see this message
The problem usually goes away quickly without you doing anything. Try sending the email again later.
If you keep getting the error:
- Check if there are any mistakes in the recipient's email address.
- Contact the customer service department of your recipient's email provider. For example, if you're trying to send an email to firstname.lastname@example.org, contact Example's service department.
If you see this error when sending messages to someone at your work, school, or other organization, talk to your administrator.
