We are an IT enterprise and we are some IT managers to make support to our clients.

All IT managers need be owners form our customers Tenants to give support or make some actions in the Tenants Customer.

The option offered by Microsoft to do it is invite all IT managers accounts (from our tenant), make it members of a local group and give owner role to this group.

It was very usesfully if it was possible to invite or link a grop from foreign tenant (our tenant) and then don't be to invite accounts one-by-one.

Thanks
