Hello @romankorchak2, @Anonymous
the message which should be coming is send via Dynamics and a Flow called "Send Passwort Reset To Contact".
Go into advanced setting and under flows you will find that one. You can than have a look which mailbox is entered and which text shall be send as well as some protocols.
A common issue is that you use a mailadress as from which is not free for sending messages as others.
You will find more on that here: https://learn.microsoft.com/en-us/power-platform/admin/send-email-on-behalf
In some cases you also have to allow sending emails as other person in the exchange settings.
After that it should work fine.
Another way to troubleshoot is using the dynamics filter and use activities + activitytype E-Mail and see what's send or what the current status is.
