I need to run a power shell script that allows me to see what shared mailboxes a particular user has access to.  I have tried running the cmdlet below but its not working.  Im using Exchange 2010.

Get-Mailbox | Get-MailboxPermission | ?{($_.AccessRights -eq "FullAccess") -and ($_.User -like 'DOMAIN\user') -and ($_.IsInherited -eq $false)} | ft Id*

I change the domain\user to replicate my domain and users alias.

Is there any other power shell i can use to pull of what i need?

Check the below link which has details how to extract those information from the Mailboxes

Hi

Thanks for the response.  I have checked this but this does not give me the details i require.  The problem is i do not know the name of the shared mailbox the user has access to.  I only know the name and alias of the user.  So i need to search which shared mailbox this particular user has access to?

Thanks

Hi,

To get the shared mailbox list, we can use the condition RecipientTypeDetails to filter out. Try something like this:

Get-Mailbox | ?{($_. RecipientTypeDetails eq sharedmailbox)} |Get-MailboxPermission | ?{($_.AccessRights -eq "FullAccess") -and ($_.User -like 'DOMAIN\user') -and ($_.IsInherited -eq $false)} | ft Id*

Best Regards.

Don't forget that Get-MailboxPermission has the -User parameter. This one should do it much cleaner:

Get-Mailbox -RecipientTypeDetails SharedMailbox | Get-MailboxPermission -User user@domain.com

Hi 

No luck with this one, i changed teh domain and user to reflect my domain and user 

Please note i have not pasted my Domain Name nor the Users name 

Remove the space from $_. RecipientTypeDetails

Get-Mailbox | ?{($_.RecipientTypeDetails -eq "sharedmailbox")}

Also include -ResultSize Unlimited to search mailbox more than first 1000

Get-Mailbox -resultsize Unlimited | ?{($_.RecipientTypeDetails -eq "sharedmailbox")} |Get-MailboxPermission | ?{($_.AccessRights -eq "FullAccess") -and ($_.User -like 'DOMAIN\User') -and ($_.IsInherited -eq $false)} | ft Id*

However I would do like this to get server side filtering with shared mailboxes and get faster result

Get-Mailbox -resultsize Unlimited -RecipientTypeDetails SharedMailbox |Get-MailboxPermission | ?{($_.AccessRights -eq "FullAccess") -and ($_.User -like 'DOMAIN\User') -and ($_.IsInherited -eq $false)} | ft Id*
