Create a Transport Rule to Reject a Message When Both Domain Conditions Are Met

Today, I saw a question come up as to how to block a message when it’s sent to two different classes of users at the same time.  Let’s say you want to be able to send to John@domain1.com, Bob@domain2.com, and Jane@domain3.com (list 1) or to Mark@domain4.com, Sue@domain5.com, and Mary@domain6.com (list 2), but any time those users from both list 1 AND list 2 appear in the To/CC of the *same* email message, you want it to be blocked. … [ Continue reading ]

Creating a Pinpoint DNS Zone

I saw an interesting question floating around a discussion alias earlier today–how to return different IP addresses for the same hostname from different DNS servers for users that are in different regions (for example, have DNS servers on the east coast return “1.2.3.4” for my.domain.com and DNS servers on the west coast return “5.6.7.8” for same name–the trick being that domain.com is an internal Active Directory DNS zone). … [ Continue reading ]

Updating Remote Recipient Types on-Premises

During migrations from third-party platforms like Gmail or various POP3 providers or from hosted Exchange environments, we frequently see customers provisioning remote mailboxes for shared resources.

This works fine for three out of four recipient types. You can run New-RemoteMailbox for a regular user or specify a Type (Room or Equipment) to get the appropriate mailboxes. … [ Continue reading ]

Office 365 License Assignment

There is perpetually a lot of angst around licensing users for Office 365 workloads.  Most of my customers over the years have wanted to ease into deployment, only enabling certain services at a time.  Of course, as an evergreen service, we are always adding features, leading to new service plans to disable as you discover them.… [ Continue reading ]

Sign an exported certificate from an F5

I’ve run into this delightful scenario a few times–the network team generates CSRs and certificates for the environment, and since they want to do SSL termination on their network devices, complete the certificate process there.  When you ask for an export of the certificate from, say, an F5, they will just give you the unsigned certificate–so that when you import it into your server, you end up with something unusable, since it has no private key.… [ Continue reading ]

Using XML to Backup and Restore Office 365 Settings

Frequently, I am asked to make changes to a customer's environment.  I'm a belt and suspenders kind of guy, so my backups have backups.  At any rate, normally when I am performing changes in a tenant (or Exchange on-premises environment, for that matter), I make two sets of backups–one by piping a Get-cmdlet to Export-CSV (so I have a readable copy), and one by piping the same Get-cmdlet to Export-Clixml (so I have a way to set the nodes as parameters and import them back).… [ Continue reading ]

Customizing the Windows PowerShell Console

Another blog on customizing the PowerShell console?  Really?

Yes.  This is actually what I use on a day-to-day basis as a consultant managing many projects at once.  I find that I’m usually running various PowerShell sessions concurrently and having to keep which one is which can be difficult without having to stop and check which server or Office 365 tenant I’m connect to, or what type of activity I’m performing.… [ Continue reading ]

Disconnect all PSTs from the Default Outlook Profile

Today, one of my consultant peers posed a problem to me: a customer wanted to import all PSTs into Office 365 archives, but in order to do that, had to disconnect them from the user’s default Outlook profile.

Fortunately, you can expose a number of methods and properties from the Outlook ComObject inside PowerShell, so this wasn’t terribly difficult (although, I’m still trying to figure out how to do this against all Outlook profiles configured).… [ Continue reading ]

Office 365 PAC File

When we talk about Office 365 services with our customers, a lot of the discussion revolves around the networking components.  While we generally have a “good idea” of networking, we’re not experts in your technology and will frequently tell you to go talk to your vendors. … [ Continue reading ]

Exchange 2013 Management Server for Office 365

For most of our large enterprise, commercial, and government customers, an Exchange hybrid environment provides a validated and supported method for deploying, migrating, and managing both an on-premises Exchange organization as well as Office 365. 

In some cases, though (such as migrating from a hosted platform or other 3rd-party products that don't have Active Directory integration), you may not need everything hybrid provides or may not have a need to support the infrastructure migrating mailboxes cross-premises.  For that, I've created a tool to help accelerate configuring Exchange to set and manage attributes and enable-cmdlets (such as Enable-RemoteMailbox).… [ Continue reading ]
