If you need to change the purpose of an existing Exchange Mailbox, for instance changing a User Mailbox to a Shared Mailbox or maybe the other way around, changing a Shared Mailbox to a User Mailbox.

Could also be changing to a Room or Equipment.

This an relative easy task to change. Make sure your running the Exchange Management Shell or are connected Office 365 (see previous post).

Change a mailbox to a Shared Mailbox, using the following PowerShell command:

Get-Mailbox -Identity user@userdomain.com | Set-Mailbox -Type Shared

The different Recipient Types you can set on a Mailbox are:

• Regular
• Room
• Equipment
• Shared

Show a list of mailbox and their Recipient Type, using the following PowerShell command to validate your configuration settings:

Get-Mailbox | ft Name, RecipientTypeDetails

Output (example):

The above commands works fine on Exchange 2007, Exchange 2010 and with Office 365.

If you need to give Send As Permissions to a User in Office 365, it can be done using a few simple commands in Exchange Online PowerShell.

Send As permission is used when you need to give a user permission to use another recipient’s email address in the From address.

First connect to your Office 365 tenant, using Windows PowerShell.

To connect to Exchange Online, just start a PowerShell session and type in following commands:

$Cred = Get-Credential

The above command prompts you, for your Office 365 tenant admin credentials, it is important to enter as UPN format, such as e.g. admin@contoso.onmicrosoft.com.

Next, we will create a new remote PowerShell session using the following cmdlet:

$s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred -Authentication Basic –AllowRedirection

Next we import of the PowerShell session:

Import-PSSession $s

You are now connected to Exchange Online with you Office 365 Tenant admin and can use Exchange Online PowerShell cmdlets available.

Next grant a user permission to access another user’s mailbox, so they have permission to open it:

Add-MailboxPermission <mailbox> -User <user or security group> -AccessRights FullAccess

Then give Send As permission to users, som they can send as the user:

Add-RecipientPermission <identity> -AccessRights SendAs -Trustee <user>

As an Administrator for Office 365, you can use PowerShell to manage a lot of your administrative tasks such as user management and domain management.

The following is needed:

1. MS Online Services Assistant needs to be downloaded and installed
2. MS Online Module for PowerShell needs to be  downloaded and installed
3. Connect to Microsoft Online in PowerShell

Download MS Online Services Assistant

Download the OS version needed:

• Microsoft Online Services Sign-In Assistant – 32 bit version
• Microsoft Online Services Sign-In Assistant – 64 bit version

Download Online Module for PowerShell

Download the OS version needed:

• Microsoft Online Services Module for Windows PowerShell (32-bit version)
• Microsoft Online Services Module for Windows PowerShell (64-bit version)

Connect to MS Online in PowerShell

Open a PowerShell session and import the MS Online Module using:

Import-Module MsOnline

 

Connect with your Microsoft Online tenant account using:

Connect-MsolService

 

Use your tenant account e.g. admin@contoso.onmicrosoft.com.

Now you are ready to work with PowerShell against your Office 365 account. If you need a list of the cmdlets available, see the reference documentation link below or run the following PowerShell command:

Get-Command -Module MsOnline

 

Reference documentation:

• Use Windows PowerShell to manage Office 365
• Overview over the Windows PowerShell cmdlets for Office 365

By default when Exchange Online in Office 365 is setup for your organization, the postmaster address, e.g. postmaster@domain.com is set to postmaster@domain.onmicrosoft.com.

This means that when someone sends mail to your organization and gets an NDR back, the sender is: postmaster@domain.onmicrosoft.com.

If you want to change this, you can do so using PowerShell for Exchange Online.

The procedure for changing this is:

1. Connect to your Exchange online using PowerShell

2. Change addres using command:

Set-TransportConfig –ExternalPostmasterAddress postmaster@domain.com

 

This works for All P and E plans – I have not tested it yet for K plan.

This postmaster address is a tenant/organization level setting which applies to all domains in your tenant. It is not available to set the postmaster address on a domain level.

As usual Microsoft has put all the sessions from this years TechEd online at www.msteched.com.

I have compiled a list of interesting UC sessions within:

• Exchange 2010
• Lync 2010
• Office 365

All session links include a webcast of the session along with the powerpoint.
