We have built a cool reporting tool www.sswEagleEye.com that uses the Microsoft Graph API to produce insights into employees’ email data.

However, when an employee leaves the company, we are no longer able to access that former employee’s email messages. This makes sense normally, but not in our scenario.

We need former employees’ email data or we have incomplete and potentially misleading reports.

Suggestion:
Microsoft Graph API should provide a method to access former employees’ email data, either through a dedicated endpoint or by incorporating a flag or parameter in the existing API requests.
