Issue: Active/Inactive users on CoreView seems wrong
CoreView relies on multiple sources of data from PowerShell, Exchange Web Services, Graph, Management API, Azure AD Audit, just to name a few.
Data retrieved can have various latency (up to 72 hours) and some can be completely missing due to tenant configuration/restrictions.
Solution:
Here is step-by-step guide to troubleshoot the problem:
1. Check if anonymous report is enabled On your tenant, this scrambles all data and makes usage stats impossible to retrieve. (Moreover stats data are still available in clear in many places on Microsoft Portal like: Teams Admin Center, Exchange Admin Center, Azure AD Admin Center.
Connect to Microsoft Admin Center - Settings - Org Settings – Reports
Verify that settings like in the picture below:
2. Check Exchange Activity
Exchange Last Date is a complex matter on the Microsoft side, it is revised continually. Now the most precise information is retrieved from Graph and it's available in the Exchange Activity Report:
https://portal.coreview.com/Admin/20210104132649/#/exchangeReports/ExchangeEmailActivity
This date is updated by Microsoft if there are Mail Read or Mail Sent in the selected date range.
This data are retrieved from Graph API: https://docs.microsoft.com/en-us/graph/api/reportroot-getemailactivityuserdetail?view=graph-rest-1.0#response
Last activity date refers to the last time the user performed a read or send email activity. It is mapped on the field Last Exchange User Action Date.
Note: it can happen that a User’s Disabled (Blocked Credentials) are marked as active in CoreView, this means that another user is accessing their resources (mainly happening for Mailboxes, OneDrive)
3. Check Teams Activity
Teams Activity is retrieved from Teams Users Activity Report:
