Mail enabled security groups are not allowed

A common issue!

When you're trying to create a security group in Azure, and you're getting the error "Mail enabled security groups are not allowed", it's likely because you're trying to create a security group that is also a mail-enabled security group.

In Azure, a mail-enabled security group is a security group that is also a recipient in Microsoft 365 or Exchange Online. This means that the security group has an email address and can receive emails.

To resolve this issue, you have a few options:

  1. Create a non-mail-enabled security group: You can create a security group without enabling mail. To do this, simply create a new security group and don't select the "Mail-enabled" option.
  2. Use a different naming convention: If you're trying to create a security group with a name that is similar to an email address, try using a different naming convention. For example, instead of using "[email protected]" as the name, use "example-security-group" or something similar.
  3. Use a different Azure subscription or tenant: If you're trying to create a mail-enabled security group in a specific Azure subscription or tenant, try creating it in a different subscription or tenant. This might resolve the issue if there's a specific configuration or policy in place that's preventing mail-enabled security groups.

Remember to always check the Azure documentation and any specific requirements or restrictions for your Azure subscription or tenant before creating a security group.
