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 ]

Wipe Content from an Exchange Online Mailbox

This tool has been updated with new options.  See https://www.undocumented-features.com/2017/10/19/update-to-wipe-exchange-online-mailbox-script/.

Periodically over the years, I’ve run into content problems trying to migrate data to Exchange Online using third-party migration tools–they somehow get stuck, don’t like something existing in the destination mailbox (or didn’t write it properly in the first place) and you need a clean mailbox to restart the process. … [ 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 ]

Subscribe to the Office 365 Service Health Dashboard RSS Feed in Outlook

*UPDATE* We have deprecated the Service Health Dashboard RSS Feed. For service health updates, you can go to https://portal.office.com/adminportal/home#/servicestatus.

Periodically, services in Office 365 may become affected by a number of things (network availability, regional network disruptions, upgrades to the service environment, etc).… [ Continue reading ]

Switching from Federated to Cloud Auth (AD FS to Dirsync/AADSync + Password Hash Sync or Password Hash Sync Failover)

A few years ago, we released “DirSync with Password Hash Synchronization,” and it was kind of an all-or-nothing choice.  You could either have a synchronized account database with synchronized password hashes (so users would authenticate in the cloud), or a federated environment. … [ Continue reading ]

Configure Coexistence Mail Routing without a Secondary Routing Domain

Recently, I had to work with a customer whose existing mail host was (surprise) not excited to configure a secondary domain for us to help migrate out of the hosted environment.

To give a little background, when we configure a traditional hybrid environment (I love using those terms together), we are configuring two disparate environments to share a single address space. … [ Continue reading ]
