Mail Delivery System
For various emails, we are getting the following error:
This message was created automatically by mail delivery software.
A message that you sent has not yet been delivered to one or more of its recipients after more than 8 hours on the queue on bosmailout03.eigbox.net.
The message identifier is: 1q1pDc-00060D-TK
The subject of the message is: FW: worksheet
The date of the message is: Wed, 24 May 2023 09:55:58 -0400
Delay reason: SMTP error from remote mail server after pipelined sending data block:
451 4.7.500 Server busy. Please try again later from [66.96.187.3]. (S77719) [DM6NAM10FT066.eop-nam10.prod.protection.outlook.com 2023-05-24T23:08:21.858Z 08DB5C9A7A08FF05]
No action is required on your part. Delivery attempts will continue for some time, and this warning may be repeated at intervals if the message remains undelivered. Eventually the mail delivery software will give up, and when that happens, the message will be returned to you.

Hello,
It looks like this bounceback is being received when sending to a person using an email with Outlook, or a Microsoft related email. We are unfortunately aware of this issue as engineers continue to try to resolve this completely. While not ideal, we may have to ask you to try sending the email once more but from another email address not currently associated with your domain to ensure deliverability.
We sincerely do apologize for the inconvenience, and we will make sure to provide an update here on the community when the issue is fully resolved.
