AD request does not return all requested attributes

Hi,

my C# .NET 4.8 application is requesting contacts from a Active Directory. The request contains the list of attributes that should be returned. That works very good for really a lot of customers.
Of course one customer has a problem. In this case the attribute "mobil" is not returned.
I see, that this attribute is contained in the request.
The customers admin took a look at the AD with a AD administration tool, I do not know the name, and does not found any difference to the other attributes.

Do you have any idea, what could be the problem?
Thanks
Christian
