Microsoft 365 profile pictures will source photos from a few places:

1-Teams
The admin might have turned off the ability to easily edit the photo directly in MS Teams:
https://teams.office.com

2-delve/contact-info
In addition, the admin might have turned off the ability to view, access or change contact information in Delve:
https://delve.office.com

3-outlook
Further, the admin might not assign email accounts @domain.tld. As a result, we cannot login to email to access anything:
https://outlook.office.com

4-sharepoint
The following might work if MS Teams photo cannot be changed, Outlook365 is not being used and Delve is not available. If it allows the change, give 72 hours before it fully syncs the photo:
