    Hello All,

    I have a DL which contains the users list and i have to remove automapping feature for them.

    we have more than 3 sharedmailbox and 50+ users per sharedmailbox to disable this feature so i can't do it manually.

    Hi,

    If the full access permission has been assigned to 50+ users in the distribution list and you just want to remove auto-mapping on an existing shared mailbox and remove the auto-mapping behavior for users who have already been granted Full Access permissions. We can try the following command:

    $FixAutoMapping = Get-Content c:\users.txt

    $FixAutoMapping | ForEach {Remove-MailboxPermission -Identity SharedMailbox1 -User $_.User -AccessRights FullAccess}

    $FixAutoMapping | ForEach {Add-MailboxPermission -Identity SharedMailbox1 -User $_.User -AccessRights:FullAccess -AutoMapping $false}

    Hope it works.

    Thanks,

    Just quickly constructed this for your, haven't try this so make sure you try this on a test shared mailbox by granting access to a test user before running for all 3 shared mailboxes...

    $users = Get-Content c:\users.txt
    foreach ($user in $users)
    {

    $userfind = "*" + $user

    Get-MailboxPermission YourSharedMailboxNameHere | where {$_.AccessRights -eq "FullAccess" -and $_.IsInherited -eq $false -and $_.user -like "$userfind" } | Remove-MailboxPermission -Confirm:$false

    Add-MailboxPermission YourSharedMailboxNameHere -User $user -AccessRights:FullAccess -AutoMapping $false

    }

    Or you can open the shared mailboxes via ADSIEdit and go to msExchDelegateListLink attribute and remove the users that you don't want automapping for.

    Thanks Amit. Sorry i missed one information. I have exchange 2010 sp2. When i ran the below script i got this error.

    User or group "Userlogonname
                   " wasn't found. Please make sure you've typed it correctly.
        + CategoryInfo          : InvalidData: (:) [Add-MailboxPermission], ManagementObjectNotFoundException
        + FullyQualifiedErrorId : FAC24C45,Microsoft.Exchange.Management.RecipientTasks.AddMailboxPermission

    Script:

    $users = Get-Content c:\users.txt
    foreach ($user in $users)
    {

    $userfind = "*" + $user

    Add-MailboxPermission YourSharedMailboxNameHere -User $user -AccessRights:FullAccess -AutoMapping $false

    }

    I believe above one line is enough if i have SP2 so i removed Get-Mailbox line from your script. Please help me

    If I understood correctly all 50 users are having mailbox access currently but you just want to remove the automapping for them. 

    In fact to remove automapping you first need to remove the access and add the full access back with -automapping $false so actually my line "Get-MailboxPermission YourSharedMailboxNameHere | where {$_.AccessRights -eq "FullAccess" -and $_.IsInherited -eq $false -and $_.user -like "$userfind" } | Remove-MailboxPermission -Confirm:$false" is removing the mailbox access first and then adding back.

    Error "User or group "Userlogonname " wasn't found." says its not taking the correct shared mailbox name, can you just try running Get-MailboxPermission SharedMailboxName and see if it is giving result, if that works then entire line should work...

    Thanks Amit. Now i ran the whole script and getting the same error.

    User or group "Userlogonname
                   " wasn't found. Please make sure you've typed it correctly.
        + CategoryInfo          : InvalidData: (:) [Add-MailboxPermission], ManagementObjectNotFoundException
        + FullyQualifiedErrorId : FAC24C45,Microsoft.Exchange.Management.RecipientTasks.AddMailboxPermission

    I'm very sure my sharedmailbox name is correct and as well the logon name in text file because when i ran the below script manually it get successful.

     Add-MailboxPermission "India Mail" -User macman -AccessRights:FullAccess -AutoMapping $false
