Hi Simbarashe,

This is purely office 365 online.

No on site AD or service.

Answer 2

Hello Dale Chapman1,

Good day! Thanks for posting in Microsoft Community. We are happy to assist you.

May I know if you have a hybrid deployment of on-premises Exchange Server and Exchange Online in Office 365?

The error message you are getting “This message could not be sent. Try sending the message again later, or contact your network administrator. You do not have the permission to send the message on behalf of the specified user. Error is [0x80070005-0x0004dc-0x000524].” Is usually happens when The value of the LegacyExchangeDN attribute changes during the mailbox move. This issue occurs if the old LegacyExchangeDN attribute wasn't added as an X500 address to the email addresses for the recipient when the mailbox was moved.

To solve this issue, you need to manually update the user's email addresses by adding the value of the LegacyExchangeDN attribute as an X500 address. To do this, determine what the X500 address is, and then add it to the user's email addresses. For detailed steps on how to determine and add the X500 address please see the attached document "0x80070005-0x0004dc-0x000524" error when a user sends updates to Calendar items that were created before Exchange Online migration - Microsoft Support

We look forward to hearing from you; Please understand that our initial reply may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution. Thank you for your cooperation.

Sincerely,
