Hi all.

I am trying to load user folders with call to list user folders , and later emails for given folder with call to list emails in given folder .
In both calls common part is:

GET /users/{id | userPrincipalName}…

On Azure portal userPrincipalName parameter is editable:

Is it a must to use Object ID (below) for accessing user and so forth ?

For my use case it would be of great benefit to use User principal name , but what happens if someone changes it ?

Thanks in advance,
Dragan
