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 ]
I wrote the original Proxy PAC tool for a customer almost a year ago, and since have added a lot of new functionality. Rather than updating my previous blog posts about it, I thought I would start a fresh thread. … [ Continue reading ]
Update: There are new cmdlets available for this task. This blog is for historical reference only. A new, updated process is available here (https://www.undocumented-features.com/2017/04/29/disable-office-365-groups-creation-redux/).
Office 365 Groups are a (somewhat) new feature that act both like a distribution list and a public folder or shared mailbox. … [ Continue reading ]
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 “184.108.40.206” for my.domain.com and DNS servers on the west coast return “220.127.116.11” for same name–the trick being that domain.com is an internal Active Directory DNS zone). … [ Continue reading ]
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 ]
I’ve been involved in a lot of Exchange migrations over the years, to and from all sorts of different environments.
On a current engagement, I had to export a ton of cloud-managed distribution lists and their members from Office 365 / Exchange Online Dedicated and import them into Office 365 Multitenant. … [ Continue reading ]
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 ]
A few weeks ago, I saw something come up for a peer that needed a way to manage the maximum number of ActiveSync devices that a user had connected in Office 365. Using only native Exchange policies, we can’t do that (MDM solutions solve this problem by manning the Exchange ActiveSync quarantine). … [ Continue reading ]
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 ]
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 ]
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 ]
If you’ve ever wanted to add columns for unlisted attributes to Active Directory Users and Computers, you’ve been out of luck without editing the displaySpecifiers manually.
Until I had enough of it.
How does it work? I’m so glad you asked. … [ Continue reading ]
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 ]
From time to time, an issue that crops up during Exchange or Office 365 migrations is the dreaded “insufficient access rights:”
It’s commonly manifested like this (though I have seen it displayed other ways as well):
Warning: Unable to update Active Directory information for the source mailbox at the end of the move.… [ Continue reading ]
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 ]
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 ]
So your company just bought another company. Or you’re moving to Exchange Online. Or you registered a new domain. Any reason, really, that you could want an email address template added to all of your Email Address Policies.
Not so bad if you have one or two policies But what if you have 10? … [ Continue reading ]
Ever since the advent of DirSync, you’ve been able to add a picture’s binary content to the thumbnailPhoto attribute in AD and synchronize it to Office 365. This blob would be rendered as a photo next to the user’s name in Outlook, OWA, and Lync. … [ Continue reading ]
