Powershell Exchange Cmdlet Help

I'm trying to run a PowerShell cmdlet that will tell me where a specific user (usera) has any kind of permission directly tied to a mailbox.

I'm trying to run the cmdlet below but it continues to fail. I want to find any mailbox where that user has ANY permission (Full Access, Delete Item, etc) and return it to a csv file.

Anyone know what I'm doing wrong?? Thanks!


[PS] C:\Windows\system32>Get-Mailbox -resultsize Unlimited | Get-MailboxPermission | where {$_.User -like "DOMAIN\usera"} | Export-Csv C:\Admin\usera.csv

1st when you try the cmdlet:

Get-MailboxPermission name | Format-List

Open in new window


The result will look like this:

AccessRights    : {FullAccess, DeleteItem, ReadPermission, ChangePermission, ChangeOwner
Deny            : False
InheritanceType : All
User            : domain\Enterprise Admins
Identity        : domain.com/User A
IsInherited     : True
IsValid         : True
ObjectState     : Unchanged

Try this:

Get-Mailbox -ResultSize Unlimited | Get-MailboxPermission | where {$_.AccessRights -eq 'FullAccess'} | Format-Table User,Identity >C:\Filename.txt

Open in new window

I only want it to show me where "usera"  has any kind of permissions on a mailbox, where can I add that in here? Also I want to output it to a CSV, so I assume just changing the txt to csv...

Hi,
Try the below mentioned codes:

 Get-Mailbox -Server "<servername>"  -resultsize "Unlimited" | Get-MailboxPermission | where { ($_.AccessRights -eq "FullAccess") -and ($_.IsInherited -eq $false) -and -not ($_.User -like "NT AUTHORITY\SELF") } | ft @{Name="Identity";expression={($_.Identity -split "/")[-1]}}, User -AutoSize 

Open in new window


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

Open in new window

Thanks for your help guys. The command I ended up using is this one:

Get-MailboxPermission -ResultSize Unlimited -Identity * | where {$_.User -like "ACCOUNTS\brendan"} | Format-Table User,Identity >C:\Admin\117.txt
