One of the biggest problems is .NK2 files (the Outllok Nickname look-up cache).

This file is VERY touchy. If you open it with anything and save it, the file is hosed. It will not work correctly anymore.

Here are a few things I have learned that will help anyone working with .NK2 files.

1- They cannot be over 500 KB in size. If they get that big, they will not add any more items.

2- You can delete items from them by starting a new email, and when it displays the options, highlight the one you don't want anymore and press delete. It is now gone from the cache.

3- They always get corrupted. I have found a cool utility that lets you view them (for free), but you have to pay to be able to fix it.

http://www.ingressor.com is the place where you can get the file.

4- If you cut and paste an email address into the to field, it will not add it to the cache, you have to actually type it in the to field for it to add it to the cache. I know, weird, but that is the case.

Bottom line, the easiest way to deal with them is to just delete the file and have Outlook rebuild it.]]> Microsoft Exchange Server 2007 http://www.0x80004005.net/index.php?itemid=463 Wed, 3 Sep 2008 15:35:20 -0600 http://www.0x80004005.net/index.php?itemid=461
[PS] C:\Windows\System32>get-mailbox -server ex01 | where-object {$_.Database -like "EX01\RSG1\*"} | add-mailboxpermission -AccessRights fullaccess -user mkieffer

This worked well, when I am done I will run the following command to remove the access.

This script will display what mailboxes are going to be purged, how big they are, and when they were disconnected.
Get-MailboxStatistics -server ex01 | where-object {$_.DisconnectDate -ne $null} | Select Displayname,DisconnectDate,TotalItemSize | sort-object DisconnectDate >> c:\temp\stats.txt


Output is then sent to C:\temp\stats.txt. Then you can email the results, or save them for future use.]]> Exchange 2007 - PowerShell Script http://www.0x80004005.net/index.php?itemid=460 Tue, 29 Jul 2008 10:21:44 -0600 http://www.0x80004005.net/index.php?itemid=459 Here are the commands we use

1- Generate an HTML of users to have email disabled
get-mailbox -OrganizationalUnit [REMOVED]/Corp/Users/Terminations | convertto-html -property Name,OrganizationalUnit -Title 'Terminated Users' > C:\term_log.html"

2- Do the actual disable-mailboxes
get-mailbox -OrganizationalUnit [REMOVED]/Corp/Users/Terminations | disable-mailbox -confirm:$false"


We then email the results by using a .vbs script that takes the output and emails it.

So we set-up a script that runs every day and takes all the users in an OU that are not mail enabled and then we mail enable them. (We ONLY wanted the ones in the parent OU, not the sub OUs. Our contractors and terminated employees are in sub OUs).Here is the script:


$a = get-user -OrganizationalUnit "[REMOVED]/Corp/Users" -RecipientTypeDetails "User" | where {$_.DistinguishedName -notlike '*OU=Generic Accounts,OU=Employees,OU=Users,OU=Corp,DC=[REMOVED],DC=int' -and $_.DistinguishedName -notlike '*OU=Contractors,OU=Employees,OU=Users,OU=Corp,DC=[REMOVED],DC=int'}

remove-item d:\scripts\newusers.txt

$date = get-date

Add-Content d:\scripts\newusers.txt "=============================================="
Add-Content d:\scripts\newusers.txt "Starting New User Mailbox Run"
Add-Content d:\scripts\newusers.txt " "

foreach ($item in $a) {

Add-Content d:\scripts\newusers.txt "Creating Mailbox for: $item"

enable-mailbox -Identity $item -Alias $item.SamAccountName -Database "EX01\TempSG1\TempSG1-MS1"

}

Add-Content d:\scripts\newusers.txt "SamAccountName (Department) WindowsEmailAddress "
Add-Content d:\scripts\newusers.txt " "

$b = get-mailbox -Database "EX01\TempSG1\TempSG1-MS1"

foreach ($itemb in $b) {
$userdata = get-user $itemb
$userdatastring = $userdata.SamAccountName + " (" + $userdata.Department + ") " + $userdata.WindowsEmailAddress

Because we add them to a temporary mail store, we then generate a list that shows us what department they user belongs to. Then we can move them to the correct mail store (we base mail store membership on department) the following week.

The main problem we ran into was that it would also include all of the users in the the sub OUs (contractors, and terminations). So this script only adds thoes in the parent OU, not the sub OUs. We also needed to add the second part to add users that are mail users, but don't have mailboxes.]]> Exchange 2007 - PowerShell Script http://www.0x80004005.net/index.php?itemid=456 Tue, 29 Jul 2008 10:08:37 -0600 http://www.0x80004005.net/index.php?itemid=455
First you create a Security group that contains all the users you wish to be list owners (ability to modify list membership). Then you can use the add-adpermission commandlet to create the membership.

In this example we have a distribution list called "MF Mentors" and a security group called "Distribution List Editors". This is the command you can use to do this.

[PS] C:\Windows\System32>add-adpermission "MF mentors" -user "Distribution List Editors" -AccessRights ReadProperty,WriteProperty -Properties Member

You should then be able to see the following if you get-adpermission on that distribution list.

User : [DOMAIN INFORMATION]\Distribution List Editors
Identity : [DOMAIN INFORMAIONT]\MF Mentors
Deny : False
AccessRights : {ReadProperty, WriteProperty}
ExtendedRights :
IsInherited : False
Properties : {Member}

$a = get-recipient -ResultSize Unlimited
foreach ($recipient in $a) {
$b = get-recipient $recipient.alias
foreach ($item in $b.EmailAddresses) {

We needed a way to have their Mailbox disabled as well. So we setup a at script that does this.
To run the script, you need to use the following command:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -PSConsoleFile "C:\Program Files\Microsoft\Exchange Server\bin\exshell.psc1" -command ". 'C:\ps-scripts\terminated_users.ps1'”

This will runn the script termiated_users.ps1 as an Exchange PowerShell script.

Here is what the termiated_users.ps1 script contains:

get-mailbox -OrganizationalUnit "myfamily.int/Corp/Users/Terminations" | disable-mailbox -WhatIf


Basically the script grabs all the mailbox objects in the Terminations OU, then disables them. You will want to remove the -WhatIf after you verify that it is only affecting the accounts you want affected.
