With the rise of stay-at-home orders due to COVID-19 over the past several weeks (now turned months), I’ve engaged with many customers who want to use Microsoft Teams to as part of their work-from-home tool set. … [ Continue reading ]
Yes. I said it.
Someone needed to put a line in the sand and today, that person is me. I’m going to say these are some best practices.
But of course, your mileage may vary, depending on your type of organization (users at a local bank or city government will have different threats presented to them than an engineering firm with international customers, for example). … [ Continue reading ]
I’m gonna channel the great Etta James:
Ok, I’m back.
I’ve been waiting for this feature for what seems like an eternity–the ability for a mailbox that has multiple proxy addresses to send from any of those addresses.… [ Continue reading ]
After I re-posted a quick script to export all of the Windows Vault credentials, one of my good friends, Aaron Steele, threw down the gauntlet:
To that, I say …
Yes, it’s rushed and messy (and has a couple of quirks), but gauntlets have to be responded to quickly and all.… [ Continue reading ]
This week, I’m exploring some of the basics of Conditional Access and using it with Microsoft Teams.
In the “legacy” world (the term we attach to most things that aren’t bleeding edge these days), we typically saw organizations build the high, high walls and dig the deep, deep moats (and occasionally fill them with alligators) to keep the bad guys out.… [ Continue reading ]
Friday, while building a new lab to use while writing a chapter for our new Microsoft Teams book, I went through the normal process in Exchange to request a certificate and apply it. Easy peasy normally, right?… [ Continue reading ]
It’s literally been a year since I’ve updated it–mainly because we haven’t made any significant endpoint changes.
I did detect some CRL endpoint updates and a few other odds and ends for Worldwide Commercial and GCC Moderate, so I’ve updated the AAD Network Communications Test tool accordingly.… [ Continue reading ]
While updating the my Public Folder IDFix tool, I was testing the [
Net.Mail.MailAddress] class. I’ve used it in the past, and it seemed to be a pretty simply way to check for valid addresses, but I started running into problems with it not detecting some things that were obviously not in the RFC.… [ Continue reading ]
Since the TechNet Gallery retirement, I’ve had several users contact me regarding the Public Folder IDFix tool that I put out almost 6 years ago. I don’t do a lot of Exchange Public Folder migrations any more, so I shelved a lot of updates and things that I had planned for my public folder tools.… [ Continue reading ]
A customer I was working with last week had trouble tracking down all the places that an email address was placed in an allow list–across multiple transport rules and other filter policies.
Just plodding away here–moved the Get-ActiveSyncDeviceReport script to PowerShell Gallery. What is this script, you ask?
Well, you can use it to export a mailbox’s associated ActiveSync Device IDs–great info to have for documentation, security, or during a migration planning event where you need to populate permitted devices.… [ Continue reading ]
This week, I was helping someone troubleshoot authentication issues when hybrid migration mailboxes to Exchange Online.
In order to migrate a mailbox successfully, the EWS endpoint virtual directory should have NTLM/Negotiate authentication method available.… [ Continue reading ]
Sometimes, you just get too much stuff, and you need to filter it.
It’s true in life, with YouTube cat videos, and with M365 Content Search.
In this post, we’ll talk about using the FolderId parameter to include/exclude mailbox folders in a content search. … [ Continue reading ]
As I mentioned in my previous post, I’ve been trudging towards migrating the 60 or so tools, modules, and scripts I published on the now-retired TechNet Gallery over to the PowerShell Gallery.
I want to make sure I migrate the things that people find most useful–so far, I’m about halfway and wanted to do a quick check-in:
Let me know what tools you’re looking for and I’ll prioritize getting those up!… [ Continue reading ]
Post Technet Gallery requirement, I’ve been slowly going through my tools and updating them for the PowerShell Gallery. I came across this tool I built for troubleshooting a deployment at a customer a few years ago and immediately dove into updating it with new endpoints.… [ Continue reading ]
