Prompt: LodgeiT is unable to send client emails, please ensure that the mailbox is reachable or that the configurations are correct.
Due to LodgeiT logs, the issue occurs because the connection to user's Microsoft mailbox (in this case johndoe@gmail.com) is expired.
The sser needs to re-connect it https://go.lodgeit.net.au/settings/email, so all emails to their client will be sent
In this particular case the backend error message "AADSTS70000: The user could not be authenticated as the grant is expired. The user must sign in again."
