I own the domain richel.org . It is registered at hover.com, and I have Olm.net host a website for me with that domain name.
Now to verify my ownership of the domain name, Microsoft wants me to add a txt record at my DNS hosting provider.
Well at my registrar I am able to do that myself. Hover.com allows me to add such a record. I added it, and waited more than 72 hours, nut nslookup couldnt find it and neither did MS.
In its wizard for registrars/providers Office 365 offers Hover.com, but not Olm.net. I have now removed the new record from Hover and asked Olm.net to add it, which they have just done for me.
Suppose after a few hours the OLM.net newly added DNS-record responds (with NSLookup, how can I then verify this in Office 365?
