Can’t verify domain in Office 365

Share this:

Hello my friends,

If you are getting the following error message and you are sure that all DNS entries were added properly, you may be right! I’m having this issue with my personal domain where I associated and validated the domain a long time ago with a test account for an articles series and even though my Office 365 trial account has expired for months I can’t use that domain anymore.


The solution? There is nothing that you can do at your end, you must open a ticket with Microsoft Support and they will give a couple of options: allow you to log on your old account and delete the domain from there or start a internal process to clean up the domain (I’m not sure about this one because I haven’t got there yet but it seems like that is the plan B).
