Teltonika RMS - New invitation

Hi when adding a new user via email invitation to a particular email address on new Teltonika RMS account I get an error below.

Email message delivery was not successful due to error:
Mailbox does not exist (SMTP status code 5.1.1)
Verify that the email address is correct and try resending the invitation again.

The email address was previously used on another RMS account and was deleted.
We have moved it over but it seems its stuck.
Its a particular email addresses which I can share via PM.

Its not a antispam issue or mailbox issue as the error appears within a matter of seconds.
I need to speak to someone in support.


In order to resolve the issue that you are currently experiencing, additional provision of further confidential details, including your personal RMS information, is required. Due to the public nature of this forum, private communication here is not feasible. Hence, it is recommended that you reach out to your designated sales manager or the reseller. They will be able to assist you in addressing this matter more effectively.

Kind Regards,
