Exchange 2010 OWA- Open Other User Mailbox
- by Benjamin Jones
I just started working for this small firm (30 people) a little bit ago, replacing their System Admin. First thing I noticed was Exchange Server 2010 was WAY out of date. Believe it or not they did not have SP1 installed. So after I installed and configured Exchange 2010 SP3 and redirected OWA I noticed something in OWA. I could add ANYONE's User Mailbox WITHOUT giving mailbox premission. I created a couple test users, same thing. I even had another employee provide me access to their OWA and they could open anyone's Inbox without granting permission. I don't want to play the blame game, but I was SHOCKED that this was going on. Luckly being such a small company I'll be able to cover this mistake that I did not create, BUT HOW?
My guess is that I need to find out where the past System Admin went wrong in providing Full Access Permission? Or could this be a Auto-Mapping issue?
I found this article: http://technet.microsoft.com/en-us/library/hh529943.aspx
This might work $FixAutoMapping = Get-MailboxPermission sharedmailbox |where {$_.AccessRights -eq "FullAccess" -and $_.IsInherited -eq $false}
$FixAutoMapping | Remove-MailboxPermission
$FixAutoMapping | ForEach {Add-MailboxPermission -Identity $_.Identity -User $_.User -AccessRights:FullAccess -AutoMapping $false}
However how do I insert the above code into Powershell?
Again I was thrown into this mess and I'm just trying to iron out this tangled mess.
