The hosting venue has changed to serve you better.
This past week has seen the widespread growth of the WannaCry ransomware attack, which was based on the EternalBlue SMB vulnerability. We released security update MS17-010 on March 14, 2017 to address the vulnerability.
Preliminary reports show at least 300,000 computers have been affected globally by this ransomware that encrypts files, requiring up to $600 in bitcoin payments within 7 days before the data is deleted.… [ Continue reading ]
I’ve been working on a little project, and the need to retrieve the last n number of commands I’ve executed in PowerShell has become a tedious task. As you’re (hopefully) aware, Get-History is a great cmdlet to review exactly how you got to where you are. … [ Continue reading ]
From time to time, you may find that you need to selectively filter out users going to Office 365. The easiest way to do it is with a scoping filter. We do have some documents on setting the cloudFiltered attribute in the metaverse to True, but that requires creating new rules. … [ Continue reading ]
Update: I posted roll-back steps at the bottom of the article.
Several months ago, I wrote a blog on Disabling Office 365 Groups. It seems as though we couldn’t leave well enough alone. Such is a price of progress.
I got a new laptop a few weeks ago, and then found myself in the position of helping out a few colleagues this week. … [ Continue reading ]
Update: Shameless plug: I’ve written more extensively about public folder migrations from both the 2007/2010 and 2013/2016 perspectives in the book, “Office 365 Administration: Inside Out,” available at http://aka.ms/thebookonit.
So, tonight I started the last phase of one of my longest-running projects since joining Microsoft–an Exchange Online migration for a school district that I began nearly a year and a half ago. … [ Continue reading ]
This afternoon, I ran into a customer with a very interesting configuration–a 300-user department with 15 domain controllers spread among 6 sites.
Which, given our guidance in the past didn’t seem that out of line (redundant domain controllers at each site to process logons).… [ Continue reading ]
Let’s say you’re in one of the following scenarios:
While migrating users via MRS between organizations (especially to Exchange Online), a pretty common error that I run across is:
You can’t use the domain because it’s not an accepted domain for your organization.
This error is generated because the MailUser object of the user you’re attempting to migrate has a proxy address attached to it that is NOT an accepted domain in your target organization or tenant.… [ Continue reading ]
This script and the accompanying post have been updated.
I saw a request come through the other day for a method to remove unwanted proxy addresses for contacts. I’d had some code sitting around from a project a few years back and decided to freshen it up, and maybe add some newer tricks.… [ Continue reading ]
This afternoon, while configuring AAD Connect for a customer, I ran into a new error when I clicked Install at the end of the installation wizard:
An error occurred executing Configure AAD Sync task: Unexpected exception thrown. Action: PingProvisioningServiceEndPoint, Exception: An error occurred.… [ Continue reading ]
I find myself currently writing tools to both support my and other organization projects, as well as looking for ways to refine existing tools and scripts, make my life easier for future migrations, and provide additional resources to the community to help other customers more successfully use our products.… [ Continue reading ]
UPDATE: The final script has been relocated to the PowerShell Gallery: https://www.powershellgallery.com/packages/ExportImport-CalendarProcessing/5.1
During my current project, it became necessary to capture additional calendar processing parameters that are not preserved during a normal hybrid move–such as booking policies.
Some of the challenges that I faced in customer environments when writing this tool:
The first thoughts I have when building a tool generally involve four concepts:
I just built a tool for a team of consultants to use, and some of the commands require elevation. Rather than relying on telling them it needs to be elevated, I wanted to be able to exit immediately if the session wasn’t so precious time wasn’t wasted.… [ Continue reading ]
From time to time, I run into environments where things are configured in “non-standard” ways. Granted, we don’t have a lot of specificity or documentation around some attribute configurations because the default configuration has been tested by the people who created the software and works in almost every conceivable situation. … [ Continue reading ]
A few months ago, I developed a script/tool to use for a rather large customer divesting from an Office 365 Dedicated environment. As part of the exit, they wanted a contact object in their GAL for every user, contact, and distribution list that existed in the source Office 365 environment.… [ Continue reading ]
