I have a Google Workspace organization: org.com
I create a new user: sneed@org.com
Where/when/how is the sneed+alias@org.com created? How is the user sneed@org.com doing this if they don't have administrative access to organization management?
> Where/when/how is the sneed+alias@org.com created?
Where: in gmail's alias list
When: at account creation
How: gmail/gw redirect everything of the form abc+xyz@domain to abc@domain
> How is the user sneed@org.com doing this if they don't have administrative access to organization management?
The user isn't doing anything, it's a "feature" of google mail.
