I received my vouch copy from the OP within a short period of time after my request. I checked the email and password, yes it’s working.
The email is in format “sample@****.********.edu.**” so there is .edu.** in the end but it’s fine. I checked the actual site but it’s in different language so googled about login options and found that I can access this email at
https://portal.office.com/ and
https://login.microsoftonline.com/Yes, it worked. I was successfully able to change the password (but I couldn’t find any account recovery options to edit). There is no alternate email given in the account (and the alternate email field is blank and restricted to edit any information like name, alternate email) so I think OP won’t be able to change or recover account once sold (yet, I am not sure about it).
To see if this email address with such format is accepted or not, I tried to create an account on Prezi, went smooth and worked well.
I would rate 80 out of 100 considering the factors like price, email domain quality & overall user experience for this deal.
Thank you OP for giving me an opportunity to review your product / service. Good luck with the sale.
Best
