Doesn’t solve the SSO issue though unless you change your login email

I create "job function" DLs. "Company-Region-IT Manager". Then give that DL it's own SMTP address. Then use that.

It's really nice when you have to hire someone new for the position. You add them to the DL and they're automatically in control of all those accounts.

I have no idea why more companies don't do this.

Or you don't have employees using their personal email to open corporate accounts.

Still on Amazon to clearly tell people it is this way so they can properly plan for it, but employee's email addresses really shouldn't be used for the root account.
