I have changed e-mail and mobile phone and cannot connect the app to my existing Deco M5 network

My Deco M5 is perhaps 5 years old, and has been working perfect all the time.
Now I want to investigate if my Chromecast connects to the network.
But, my new phone did not have the Deco app installed, and my old e-mail address was deleted 2 years ago and I do not remember my old password.
So, I cannot log in to my existing account, and when I have created a new account with my new e-mail, then it wants to create a complete new network. Which I do not wannt since it is working fine.
I just want to get into the app.
How?

Hi, Sorry for the delay.
Only having the TP-link account ID might not help. To reset the password need to receive an auth code to this email, and you still need to access this email first.
Resetting the Deco and binding it to a valid email now will also save a lot of effort for future management. You can try to reset one of the satellite M5s first and set it up under a new email.
If you have any issues with the configuration, our hotline and chat live agents would be glad to help:

Hi, Thanks for the feedback.
Is the old email address still valid?
If we need to change the owner's email later, we need access to the old email to retrieve the password first. Otherwise, we have to factory reset the Deco(hold the bottom reset pinhole for 1s) and configure it again.

Thanks!
No, I have no access to the old e-mail account. So, I could not request a new password, since that would have been sent to the old e-mail.
Is there any help that i give you the value of the old e-mail account?
Would the serial number of the M5 help you?
I understand that on possibility would be to make factory resets on them and start again, but I do not want to do that, since that could give me other problems.
Best regards
