The hosting venue has changed to serve you better.
I happened to run into the same issue twice in one week–once with a large customer, and once with one of our partners.
Here's a synopsis of the issue:
Mailboxes cannot be migrated via 3rd-party tools because msExchMailboxGuid attribute in cloud is populated due to DirSync/AADSync.… [ Continue reading ]
Over the years, I’ve come to develop a lot of solutions (processes, scripts, workflows, and other tooling) to help customers get the most out of their investments and solve business problems.
One of the most important habits I’ve developed is making sure that I write everything down, since many customers will have similar types of issues or requirements. … [ Continue reading ]
WinRM, for those of you not in the know, is really the Microsoft answer to an age-old problem in the Windows world–remote command and task execution. It’s the Windows equivalent of the Unix rsh, a native implementation of the PsExec (albeit, with the added complexity that seeps into nearly all Microsoft technologies). … [ Continue reading ]
Here are some handy one-liners that you may find useful when managing Office 365.
Ok, some of them are a few lines, but they’re still handy.

I’ve been battling an issue for a few days now and finally stumbled upon a workable solution via PowerShell.
One of my customers has an existing Exchange 2007 deployment. The OWA instance is configured to only use NTLM authentication. ExRCA (http://www.testexchangeconnectivity.com… [ Continue reading ]
So, you’re transitioning your Exchange 2003 environment to an Office 365 environment and desperately want to drop kick your Exchange 2003 server out the door. After migrating everyone’s email, you open ESM, delete all of the mailboxes and start to uninstall Exchange. … [ Continue reading ]
So, you had a bit of nasty malware. You’re almost back to square one, but have now found yourself in the unfortunate position of having missing services–specifically the Background Intelligent Transfer Service and Windows Update services.
Never fear. These, too, can be recreated in the event that your System Restore points are borked. … [ Continue reading ]
Ran into an interesting customer issue regarding connecting to a wireless network. For whatever reason, this laptop can’t see the wireless network (though others in the office can). This laptop can connect to other WiFi networks without issue.
My laptop, for example, was able to connect without issue. … [ Continue reading ]
Tonight I found myself recovering a VM on a Windows 2008 R2 cluster connected to an MD3000i SAN. To make very long and painful story short, it appears that someone applied a series of Windows Updates and then a Dell DSM update that screwed up the multipathing.… [ Continue reading ]
Boot from VHD is a great technology that enables you to host multiple self-contained operating systems on a single hard drive. Similar to dual-booting, but you don’t have to worry about installing applications over each other or overwriting program file updates because your secondary OS is fully contained within a single virtual hard disk file. … [ Continue reading ]
Tonight, I found myself having to copy the AnyConnect binaries from one ASA 5505 to another without a device on-LAN to TFTP to. I did, however, have a public FTP server that could use to move the data around.
This feature seems to be relatively un-discussed, so here is the syntax.… [ Continue reading ]
In case your Exchange admin life wasn’t difficult enough, you can always have this problem, manifested with the following symptoms:
Classic tactics such as restarting the server or right-clicking the queue and selecting “Retry” have no effect.… [ Continue reading ]
During an SBS deployment, I ran into a few machines at my customer’s site that were running Windows XP Media Center Edition (MCE). As most of you know, the only machines that are technically eligible to join a Windows domain are “Business” class operating systems, such as Windows XP Professional, Windows Vista Business, Windows Vista Enterprise, Windows 7 Professional and Windows 7 Enterprise (although not technically “business” class, Windows Vista/7 Ultimate Editions are also able to join domains, since they’re supposed to be everything-but-the-kitchen-sink editions).… [ Continue reading ]
After getting my PIX to boot in my previous post, I decided to run through the password recovery procedures.
When meeting with a potential customer the other day, she mentioned that she had a running PIX with an unknown password.
I thought I’d refresh my PIX skills and decided to bust out an old PIX 506E we had sitting in the office.… [ Continue reading ]
