Powershell Exchange - How to list all mailboxes Full Access permission from a particular user name ?

Hi people,

I wonder if anyone here can share some Powershell script or tips in how to check if my AD user account got Full Permission access in some mailboxes ?

because for compliance reason, I need to audit if the certain AD user account has multiple Exchange mailbox Full access permission or not.

Thanks.

Get-mailboxpermission should do the trick...

Thanks Sir,

in my case here I need to know all DOMAIN\User1 mailbox full access across 2850 Exchange mailboxes.

So how do I use that command above ?

sirbounty

get-mailbox -resultsize unlimited | get-mailboxpermission | where {$_.accessrights -conains 'FullAcess'}

FOX

get-MailboxPermission username -filter "accessrights -eq 'FullAccess'" | ft samaccountname, displayname,emailaddress,AccessRights | out-file 'c:\temp\FullAccess.csv'

I see I had a type-o - conains, should be -contains, but presumably you'd find that.
Any update? Still need help?

Hi All,

The script doesn't work ?

get-MailboxPermission MyName  -filter "accessrights -eq 'FullAccess'"  | ft samaccountname, displayname,emailaddress,AccessRights | out-file 'c:\temp\FullAccess.csv'

Open in new window

A parameter cannot be found that matches parameter name 'Filter'.

Hi Sir,

I just required my own username and certain username not all username.

But yes I'll try it anyway.

Did my solution work for you?

Hi ITSystemEngineer - do you need further help or help closing the question?

List all mailboxes to which a particular user has Full Access permissions:
PS C:\> Get-Mailbox | Get-MailboxPermission -User vasil

List all shared/user/room/whatever mailboxes to which particular user has Full Access permissions:
PS C:\> Get-Mailbox -RecipientTypeDetails UserMailbox,SharedMailbox -ResultSize Unlimited | Get-MailboxPermission -User vasil

I believe this answers the question - not sure why the OP never came back.
