+Name:           Get Shared Mailbox Permission Report 
+Version:        2.0
+Website:        o365reports.com
+
+Script Highlights: 
+~~~~~~~~~~~~~~~~~~
+
+1.The script display only “Explicitly assigned permissions” to mailboxes which means it will ignore “SELF” permission that each user on his mailbox and inherited permission. 
+2.Exports output to CSV file. 
+3.The script can be executed with MFA enabled account also. 
+4.You can choose to either “export permissions of all mailboxes” or pass an input file to get permissions of specific mailboxes alone. 
+5.Allows you to filter output using your desired permissions like Send-as, Send-on-behalf or Full access. 
+6.This script is scheduler friendly. I.e., credentials can be passed as a parameter instead of saving inside the script
