Name : Find the Teams Meetings Attended by a Specific User Using PowerShell
|
||||||
|
Version : 1.0
|
||||||
|
website : o365reports.com
|
||||||
|
|

|
Script Highlights
|
||||||
|
-----------------
|
||||||
|
1. The script exports user specific Teams meeting report.
|
||||||
|
2. The script retrieves user specific Teams meeting data for 180 days, by default.
|
||||||
|
3. Allows you to obtain audit Teams meeting attended by specific user for a custom period.
|
||||||
|
4. The script can be executed with an MFA enabled account too.
|
||||||
|
5. It exports audit results to CSV file format in the working directory.
|
||||||
|
6. Automatically installs the Exchange Online module (if not installed already) upon your confirmation.
|
||||||
|
7. The script is scheduler friendly.
|
||||||
|
8. The script supports certificate-based authentication.

||||||
