Import mail contacts from csv file to AD. What is the problem?

Question

PowerShell

There is a script through which I export mail contacts from a csv file:

Import-CSV -Path "C:\tmp\users.csv" -Delimiter ";" | ForEach-Object -process {New-ADObject -Path "OU=*,OU=*,DC=domain,DC=local" -Name $_.Name -Type Contact -DisplayName $_.Name -OtherAttributes @{'givenname' =$_.givenname; 'mail'=$_.emailaddress; 'proxyAddresses'=$_.smtp; 'targetAddress'=$_.smtp; 'mailNickname'=$_.Surname; 'sn'=$_.SurName;}}

The script runs without errors, contacts are created in AD, but if you go to ecp exchange and open the created contact, an error occurs:
A mailbox is created in the email settings, but the main mailbox remains empty:
What could be the reason?
The mail contact domain is different from ours.
