Hi @Matej Čech
According to the screenshot you shared above, your issue seems to be related to RBAC, take a reference at the link here: RBAC hides the Office 365 Mailbox creation link
Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.
It’s all based around one missing role entry. To see that link you need access to the Get-RemoteDomain command. Members of Recipient Management do not have this.
New-ManagementRole -Parent "View-Only Configuration" -Name "Office 365 Provisioning Link"
Get-ManagementRoleEntry "Office 365 Provisioning Link\*" | Where { $_.Name -NotLike "Get-RemoteDomain" } | Remove-ManagementRoleEntry
New-ManagementRoleAssignment -Role "Office 365 Provisioning Link" -SecurityGroup "Recipient Management"
