Disabling the URL Preview in Office 365 email using PowerShell

You can quickly disable the Link Preview in Office 365 for a single user setting the LinkPreviewEnabled attribute to $false when you type: 

Get-MailboxMessageConfiguration –identity ebuford –LinkPreviewEnabled $false

You can also do this for All your users if you like by getting all the mailboxes and setting them at once:

get-mailbox | Set-MailboxMessageConfiguration -LinkPreviewEnabled $false

It’s Midnight, Do you know where your FSW is?

Your FSW is more important than you may think!

Over the past couple of weeks I’ve seen two Database Availability Groups that had their File Share Witness go missing on them. In both cases the server which housed the FSW were replaced and the FSW role was not recreated.

I’m guessing you’re asking yourself “how that can ever happened?” The truth is it’s a lot easier than you think. With a 2 node cluster and File Share Witness you only need 2 nodes up to have a Quorum. This means if both of your DAG servers are up good, or if one DAG server a and the FSW is up you’re still good. The problem is that a well configured Exchange server is kind of “Set it and Forget it” and losing a FSW can have no impact on you at all when the Servers are both up. However when one of your servers go offline for whatever reason, the remaining server relies on the FSW to hold a quorum. IF you don’t have enough nodes to maintain a Quorum then all your Database will DISMOUNT!

This action is by design, there is a crazy thing that could happen to you called Split Brain where you would write different data to your 2 copies of the database that leaving it out of sync. Since you don’t that to happen you need the  FSW.  The FSW is a great thing that should not be forgotten!

One way to tell if your FSW is online is to use the Fail Over Clusters powershell tools. You can do that from your Exchange Server. I always do it from the Standard PowerShell console (I don’t know why) but the module will load into your EMS as well.

Import-Module FailOverClusters


Depending on your status the output should look like one of these:


Or you could create a task to in your event log to email you if this error shows up in your Event Logs


Here’s a link on how to do that:


SBS 2011 Exchange Hybrid with Office 365

SBS 2011 Exchange Hybrid – don’t bother

The short answer is you can’t do it.

Ok that might not be enough for you so let me give you a longer answer which I hope will satisfy you and if doesn’t then good luck and God Speed!

So here’s what you’re going to hear: SBS 2010 has Exchanger 2010 on it and all you have to do is make sure it’s on SP3 and you can run the Hybrid Configuration Wizard. While this is true enough you can run the HCW you can’t however connect your Exchange server to another forest which is essentially what you’re doing when you Add the Exchange Forest.


When you go to add that Exchange Forest you’re going to start to run into issues even though you were able to run the HCW.

Notice from this next screenshot you’re getting an error message complaining about the WinRM client and all that jazz but also notice you can’t change the domain… no matter what you do here you can’t… Which means you can’t log into Office 365 which means this will not work.


I worked with a great engineer from Microsoft and between the two of us we put in way more time than we should have on this issue simply because the documentation isn’t out there that says you CAN’T do it… well here it comes. Sadly it’s not a lot of documentation but if there was enough documentation on this I would not be writing this post…

So here is the story:

You can’t add the Exchange forest because SBS 2011 won’t allow an Inter-Forest Trust


Here is a link to the document SBS 1011 FAQ the screenshot above is from Page 4.
I hope this saves you the hours of time it cost me.


Make today a little more productive!

Outlook is my number one tool for productivity, but when I not writing or answering email I don’t want it to distract me from whatever it is that I am doing.  To minimize  the distractions you can turn off the “Bing Bong you got your emails” notifications.

I’m using Outlook 2013 so this may look different for you, but find the Outlook Options page for you Outlook version and uncheck offending boxes.

This is how I did it for mine:
