Exchange 2010 - Audit who has shared their mailbox

[RabbieBurns]

How can I use Exchange Powershell to run a command that will show which users have shared their mailboxes with others please?

[RabbieBurns]

still not been able to find an answer for this on google. Is it possible?

@sukh I'm just wondering if you were perhaps able to assist here please sir?

The below script works for calendar permissions - pretty sure you could modify it for mailboxes.

 

get-mailbox -ResultSize unlimited | get-CalendarProcessing | select identity -expand ResourceDelegates | select @{n="Name"; e={$_.identity.Name}}, @{n="ResourceDelegates"; e={$_.Name}} | export-CSV c:\resourcedelegates.csv -NoTypeInformation

 

Edit - this will generate a 2-column CSV, NAme of resource - then delegates

 

If there are multiple users for a single resource it will re-write that line for each delegate.

Saying that - just been having a play. It could be as simple as

 

Get-Mailbox -ResultSize unlimited | Get-MailboxPermission | Export-Csv C:\Testing.csv

 

Just need to filter it down to "IsInherited = FALSE" and ignore all "User = NT AUTHORITY\SELF"

 

Gives you a list of all non-standard permissions.

you need to use the Get-mailboxPermission command to see who had the permission...

 

 

Get-Mailbox username | Get-MailboxPermission
