Why would two users throw errors with the API?

[snow84]

I've been using Powershell to call the API to get lists of reports users have access to. I'm using the UPN.

Invoke-PowerBIRestMethod -url https://api.powerbi.com/v1.0/myorg/admin/users/email@domain.com/artifactAccess -Method GET

This works fine for 99% of users (I'm iterating over the list of people with licenses). But there's two people (who definitely have licenses and access to reports) who throw errors.

This is the error in Powershell:

Invoke-PowerBIRestMethod : One or more errors occurred.

For example in Outlook you can examine the user properties. The "Email addresses"  tab lists all aliases. The one in caps is the primary.

[lbendlin]

is that their primary email (the one in caps) or one of the aliases?

[snow84]

How would I know if it was an alias? I'm looking in the microsoft 365 admin center and they're listed as having the license under the account

[lbendlin]

how is their email address format different from everybody else's ?

Basically everyone, including the two of them, is firstinitiallastname@domain.com
