The hosting venue has changed to serve you better.
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. If you want some background on how Proxy PAC files work and how to distribute them to your users via GPO or WPAD, I would suggest taking a look at my posts dealing with those topics:
Today, I had to subtract one list of users from another list of users. Some Excel wizards can do this with VLOOKUP, but I spend more time in trial-and-error with VLOOKUP and verifying my results that it would take to just do a CTRL-F for every object. … [ 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 This blog is for historical reference only.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://bhr.62e.myftpupload.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 ]
While working on my latest project, I encountered a significant number of objects with malformed SMTP addresses. These appeared to have been objects that had been somehow manually modified over the years by directly writing to the proxyAddresses attribute in Active Directory, bypassing an API that would check for correctly-formatted addresses.… [ Continue reading ]
Earlier this week, a question popped up on a distribution list for managing an opt-out process with Exchange Online. That wasn’t the first request I’ve seen for such a tool (in fact, I had my own customer asking for something similar). … [ 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 ]
Several months ago, I released a tool (the Office 365 Proxy Pac Gen) to generate a Proxy Automatic Configuration file that can be used to bypass local proxy servers for Office 365 services. I also wrote a blog (Office 365 PAC file) on using the tool.… [ 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 ]
This tool has been updated with new options. See https://bhr.62e.myftpupload.com/2017/10/19/update-to-wipe-exchange-online-mailbox-script/. This tool also has a new home: https://www.powershellgallery.com/packages/Wipe-ExchangeOnlineMailbox/
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 ]
