we have issues wherein we have tons of user accounts in Office 365 tenant and we have many additional Azure tenants wherein we invite users as guests to these tenants they are then linked to Azure Devops instances.

We are going through an ongoing process of migrating users email addresses, the problem is once Office 365 is updated with a new domain the guest tenants are not updated. While it is possible to script update every user in every tenant it is not possible to update the users email attribute.

This then has a knock on affect with Azure Devops licensing and authentication to Azure.

The only workaround we have is to script remove every updated user from every tenant while recording their group memberships and re-invite them to the tenants and re-add them to the groups and then
we have send a list of user addresses to Azure Devops support so that they can port across the users in each Azure Devops instances.

Can you please make this simpler, when dealing with thousands of users this is a total hassle
