If you add a new mailbox or a distribution list to your Exchange 2010 server you need to either wait for the address lists to update you can force them to update.
In the Exchange management prompt run:
Get-GlobalAddressList | update-GlobalAddressList
Get-AddressList | update-AddressList
Get-OfflineAddressBook | Update-OfflineAddressBook
On the Clients you might need to update the Offline Address Book by going to Send/Receive – Send/Receive Groups – Download Address Book…

If you want to remove all FSMO roles from a server:
Move-ADDirectoryServerOperationMasterRole -Identity Magneto -OperationMasterRole RIDMaster,PDCEmulator,SchemaMaster,InfrastructureMaster,DomainNamingMaster

In Windows Server 2008 R2 you could select whether you wanted to run Standard (GUI) och Core version of Windows Server. In Windows Server 2012 the GUI is a feature which you can add or remove.
To remove the GUI you use the following Powershell one-liner:
Remove-WindowsFeature Server-Gui-Shell, Server-Gui-Mgmt-Infra
You can also uninstall the GUI, which removes the binary files from the disk. To completely uninstall the GUI you use the following Powershell one-liner:
Uninstall-WindowsFeature Server-Gui-Shell, Server-Gui-Mgmt-Infra
If you realize you are in over your head you can add it back in using:
Add-WindowsFeature Server-Gui-Shell
… or:
Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell –Restart –Source c:\mountdir\windows\winsxs
You can also do all of this using Dism:
Dism /online /enable-feature /featurename:ServerCore-FullServer /featurename:Server-Gui-Shell /featurename:Server-Gui-Mgmt

As you might know Microsoft has a site called The Scripting Guys. My colleague Niclas Goude will be writing a couple of guest blogs on The Scripting Guys regarding security from the 2:nd to the 6:th of July.
The specific subjects will be:
Monday: Scanning
Tuesday: Brute Force
Wednesday: Shares and Metadata
Thursday: Give yourself System Permission without psexec
Friday: LSA Secrets
I did not have the possibility to visit eighter MMS or TechED North America this year but fortunately Microsoft makes all the sessions available for download. The problem is that it takes a lot of time to download the ones I want. So I tried to find a better way to do it and someone has written a script 
In the links below you will find the two scripts.

Har under en tid hållit på lite med en Exchange 2010 Server… Jag har försökt ställa in meddelandestorlek vilket inte är helt intuitivt 
. Det finns 6 olika ställen detta kan ställas in på. Här finns en bra beskrivning.
Håller just nu på att installera en Hosted Exchange 2010 lösning hos en kund och tänkte att jag skulle samla lite resurser och skriva ner lite instruktioner:
Powershell Snippets
Skapa en organisation
1: Password = Read-Host "Enter Password" -AsSecureString
2: New-organization -name TestOrg -DomainName TestOrg.com -ProgramId HostingSample -OfferId 2 -location sv-SE -AdministratorPassword $Password
Radera alla mailboxar i en organisation
1: get-mailbox -Organization TestOrg | remove-mailbox
Radera Organisation
1: Remove-Organization TestOrg
Skapa användare i Organisation
1: $OrgName = TestORG
2: Import-CSV CreateRecipients.csv | foreach {new-mailbox $_.name -userPrincipalName $_.UPN -org $OrgName -Password (ConvertTo-SecureString $_.password -AsPlainText -Force)}
Vi läser filen CreateRecipients.csv och skapar användare i Organisationen. CreateRecipients.csv skall se ut så här:
1: Name,UPN,Password
2: Nisse Hult,nisse.hult@testorg.com,P@ssw0rd1
3: Kalle Kula,kalle.kula@testorg.com,P@ssw0rd2
Lägg till mailadresser för en användare
1: $user = Get-Mailbox -identity $args[0] -organization TestOrg
2: $CLIARGS=$args[1..($args.length - 1)]
3: ForEach ($CLIARG in $CLIARGS)
4: {
5: $user.emailAddresses+=$CLIARG
6: }
7: Set-Mailbox $user -emailAddresses $user.emailAddresses
Detta script lägger till extra mailadresser för en användare. Spara scriptet som AddEmail.ps1 och kör det enligt följande:
AddEmail.ps1 [primary email] [extra email 1] [extra email 2]…

Some powershell stuff on managing Public Folders in Exchange 2007
Create Public Folder
New-PublicFolder -name "Name"
Remove a Public Folder
Remove-PublicFolder -Identity "My Public Folder"
Get information on Public Folders
Get-PublicFolder or Get-PublicFolder -Identity ""
Get information on all public folders
Get-PublicFolder -Recurse | Format-List Name
get info on all system folders (not otherwise visible)
Get-PublicFolder -Identity NON_IPM_SUBTREE -Recurse | Format-List Name
What I need to find out:
– I could not find how to create a Contacts och Calendar Folder
– I could not find out how to change permissions on the root of the Public Folder tree
– I could not change the permission on the public folders

I recently installed my first Exchange 2007 Server and I had problems with recieving mail and found it to be related to the recieve connector.
Exchange 2007 have two kinds of connector. Send connector and recieve connector.
The send connector is located on the Organisation Level and you need to create one for the servers to be able to send mail to internet.
The recieve connector is located in the server level. The Default Recieve Connector is automatically created.
Note: By default it is set up to only recieve mail from authenticated servers. This is a problem if the server is connected directly to the internet. To fix this open properties for the Default Connector and go to “Permission Groups” and click “Anonymous Users” or use Powershell:
set-ReceiveConnector -identity “Name of Default Connector” -PermissionGroups AnonymousUsers

As you know Exchange 2007 can be totally administered by using Powerscript. Here I have tried to collect some scripts for Exchange 2007 administration:
Empty a mailbox database
List mailbox servers in an organisation
get-mailboxserver
List maildatabases on current server
get-mailboxdatabase
List mailboxes in maildatabase
get-mailbox -database "Mailbox Database"
Disable a mailbox
disable-mailbox [mailboxid]
Bulk enable mailboxes for AD users:
selects all users from AD
get-user | where-object{$_.RecipientType –eq “User”}
Selects all users from the OU people
get-user –organizationalUnit people | where-object{$_.RecipientType –eq “User”}
get-user -organizationalUnit domain/OU/SUBOU | where-object{$_.RecipientType -eq "User"}
Note: This will get you only users NOT users with mailboxes
Mailenable users from CSV file
Import-CSV import.csv | foreach {enable-mailbox -Identity $_.Fullname -database EXCHSERVERMailbox Database"}
Where the importfile looks like this:
FullName,
Firstname Lastname, Change Booking Policy for resources
Set-MailboxCalendarSettings -Identity "Resource Name" -BookingWindowInDays 520
