Name: Export Shared Mailbox Size Report
|
||
Description: This script exports Exchange Online shared mailbox size report to CSV
|
||
Version: 1.0
|
||
Website: o365reports.com
|
||
|
||
Script Highlights:
|
||
~~~~~~~~~~~~~~~~~
|
||
1.The script uses modern authentication to connect to Exchange Online.
|
||
2.The script can be executed with MFA enabled account too.
|
||
3.Exports report results to CSV.
|
||
4.You can choose to either “export mailbox size of all the shared mailboxes” or pass an input file to “get usage statistics of specific shared mailboxes” alone.
|
||
5.Automatically installs the EXO PowerShell module (if not installed already) upon your confirmation.
|
||
6.The script is scheduler friendly. I.e., Credential can be passed as a parameter instead of saving inside the script.
|
||
7.The script supports Certificate-based authentication (CBA).
