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 ]
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.… [ 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 ]
A few months ago, I developed a script/tool to use for a rather large customer divesting from an Office 365 Dedicated environment.

The script for this post has been updated with new parameters and requires a new version of the BitTitan PowerShell Module.

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 ]
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 ]
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. … [ 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 ]
