On Prem Exchange Windows Server 2012 Essentials: The Script!

Exchange2A few months back, i posted up about how to deploy the On Premises Integration between WSE12 and Exchange.

powershell2xa4As part of that post i completely glossed over the method to install the Exchange Server promising to publish the PowerShell script i had written ‘soon’.

Today, my great friends, is that day.

On Premises Exchange Integration Windows Server 2012 Essentials

LogoYes, you heard me right. Hopefully by now the news of the end of development, shall we say, of SBS 2011 Standard has settled in, and you are ready for how to tackle the void left in the market. I know many partners and folks are talking about alternatives, Kerio, Hosted Exchange2Exchange or any number of other solutions, but i wanted to demonstrate how easy it is to setup the OnPrem (OP) integration with an Exchange server, and how it is possible to access both, using 1 single public IP address.

I have no idea how much it would actually cost to do in production though!

SBS 2011 Standard : Exchange 2010 Single Message Restore

sbsstdDuring a recent SMB MVP Community Roadshow event in Edinburgh, a member of the audience asked us about Email restore in SBS 2011.

Although i knew this could be done, i had never actually done it. So i decided to work out how it was done with SBS 2011.

I found a lot of great resources online that helped me with the process and i have linked to them at the end of this post.

I’m focusing on a situation where we are restoring from a backup, rather than what is available through the Exchange dumpster (aka Recover Deleted Items) although i do cover that briefly below.

Quick Fix: Outlook 2010 Sending from a second Exchange Mailbox


I have been battling this problem for some time now. It has been driving me to distraction it is fair to say.


What i didn’t realise until now, is that i was actually battling two separate issues, once i realised that it made the solution clear.

The issue i was facing was that additional mailboxes were being automatically added to an Outlook profile. This was puzzling me because firstly, i didn’t know why it was happening, and secondly i OutlookLogowasn’t able to send from that second mailbox. I could manually type in the address in the From field, but i wanted to be able to choose it and have the signature change based on the account i was using.

So a lot, of research, lab work and questions later i think i found the answers, and the solution.

Issue 1. Exchange 2010 SP1 Full Mailbox Access

Are you running Exchange 2010 SP1 with clients running Outlook 2010 SP1?

If you are, and like me you have shared mailboxes, or generic mailboxes that other users access, you may be used to setting Full Mailbox access permission on those generic accounts.

Full Access

(You would then add them to Outlook through the properties of your Primary Mailbox, under More Settings, and Advanced)

With Exchange 2010 SP1 and Outlook 2010 SP1 having given full mailbox access to an account, you may have seen a that the account that you have full mailbox access to, has automatically added itself to your Outlook profile.

You may also notice, there is no way to remove it!

auto added

This behaviour is actually well documented, but one of the best explanations i found is here.

If you don’t want to bother reading that – and you should read it – basically using Exchange 2010 SP1 EMC, EMS to add Full Mailbox Access, now also sets an Attribute on the account – msExchDelegateListLink. This attribute says which other accounts have access to this mailbox.


Outlook 2010 SP1 will look for that key now and anyone that matches, will be auto added. Quite straight forward when you know what is happening.

So that is the first part of the mystery solved.

The solution to stop this happening is easy, remove that attribute. You can either do it through ADSIEdit, or by Adding Full Mailbox Access with a script instead of using the EMC/EMS. again ill point you back to this blog for the solution.

Assuming you have now removed that attribute, you can go ahead and add the second mailbox the traditional way.


Issue 2. Outlook 2010 Send from Multiple Exchange Mailboxes

But wait – once you have done this, you still cannot select it as an account to send from?


At this point i really started to get frustrated. I was wrongly blaming Exchange 2010 SP1 for this weird behaviour and missing the clue right under my nose.

It seems that the ability to send from a second Exchange mailbox, when it is added in what i will call, the traditional manner, has been changed in Outlook 2010.

I’m running Outlook 2010 and have several exchange mailboxes open, i just had never noticed this behaviour. I’m also running Exchange 2007, and having been dealing with the issue outlined above, i never thought to look at my own Outlook.

The solution here seems to be very simple indeed.

Once you have removed the attribute, you still retain full access. That means you can add the second mailbox, as a totally separate account, and you wont be prompted to login to that mailbox, because your current credentials have permission to open it.

So to recap, first you need to make sure you remove the msExchDelegateListLink attribute from the second mailbox. Then just add that second mailbox as a second account. You will need to close Outlook down in order to do that, when adding the mailbox choose to ‘Manually Configure Server Settings..’

manually add

You will then see the mailbox as a second account.

second account

And you can choose to send from this account as well.

send from

I really hope this helps you, and saves you some time and energy!
