add a source tag for Office 365 IPs to NSG Rules
Consider adding support for multiple address ranges in NSG rules or add a source tag for Office 365 IPs.
Currently it is a nightmare to add all addresses for Exchange Online. We need a NSG policy for each address range :)
We’re addressing this need with “Service Tags” which allow network security group rules to refer to Azure services such as “Storage” or “Sql” and the list of IP addresses is maintained transparently by the Azure platform. See here for more information: https://docs.microsoft.com/en-us/azure/virtual-network/security-overview#service-tags
We’ll be adding tags for additional Azure services over time.
