New dynamic group AzureAD powershell

I am trying to make a dynamic group in AzureADMS, but I get the error message "A parameter cannot be found that matches parameter name 'MembershipRule'." This is my command:

New-AzureADMSGroup ` -DisplayName "IT"` -Description "IT-department" ` -MailEnabled $False ` -SecurityEnabled $True ` -MailNickName "IT" ` -GroupTypes "DynamicMembership" ` -MembershipRule "user.department -eq "IT"" ` -MembershipRuleProcessingState "On"

Could you please help?

Other inputs are also welcome.

I tried to reproduced in my environment and got similar error.

The error occurs as you may have had incorrect module AzureAD. So I uninstall Azure AD module and install AzureADPreview by running this command

 Uninstall-module AzureAD

Instead of Azure AD used AzureADPreview

Install-module AzureADPreview

After installed AzureADPreview, I runned your commands and got an output Successfully.
