Hello, @IniobongNkanga-8038
It's been a long time since I've heard from you, have you solved your problem yet? Did my previous reply help you？ If it was useful, you can mark it as an answer. Thank you for your understanding and support.
Thanks for posting your question in the Microsoft Q&A forum.
As Amit Singh said, can you provide a specific screenshot of the reported error? Are they using an Exchange account? Does the mailbox have a license?

Hi,
To better understand your issue please share the necessary information-
If there are any specific error messages when trying to send or receive emails?
Is the mailbox size is full?
