Just like buses, issues seem to come along in batches. In the last few customer engagements there have been a few issues with adding custom DNS domains into Office 365. Should this not be straight forward you say? Yes it should, but when we add in some deployment complexity and some interesting customer activities it leads to challenges….
The crux of the issues that I run into revolve a… Read the rest “Issues Verifying Office 365 Domains”
Being able to retrieve DNS TXT records is very useful in multiple scenarios. In this post we will look at checking the TXT domain verification record for Office 365 and also for the Sender protection Framework .
In addition to a MX record, we also have the option to prove domain ownership to Office 365 by using a TXT record. Why do we want to manually check for these Office 365 TXT records? Rat… Read the rest “How To Use Nslookup To Check DNS TXT Record”
After looking at some of the blog statistics I wanted to take brief moment and say thanks to everyone who has taken the time to read the posts over the last four years.
Time has certainly flown since I first posted this quick note on Exchange 2010 RPC Client Access back in October 2011. And it is almost a full 4 years!

In the last several customer engagements, there has been a trend to not install updates for Office 2013. Some admins thought that there was no service pack available, and others thought that the RTM build of Office 2013 was still in support. Unfortunately neither are correct viewpoints.
This means that you now need to have Office 2013 SP1 deployed on all relevant machines, as the … Read the rest “Office 2013–SP1 Now Required”
One of my colleagues emailed with an issue on their laptop. After travelling to the customer location, his power supply had “died” as it was not charging the machine. This was a Lenovo W541 with the new rectangular power connector, which meant there were no spares readily available.
Later that day when I arrived at my hotel, my W541 did the same thing. Chances of two laptops from … Read the rest “Windows 10 Laptop Not Charging After Enabling Airplane Mode”
This is an updated version of the original Windows Server 2012 post. The genesis of which was an application requirement to install Media Player onto a couple of servers. This met with some muttering and cursing from my colleague in the nearby fabric covered box, as the option to install the Desktop Experience feature is not as obvious as it was on Windows 2008 R2 which is highlighted … Read the rest “Install Desktop Experience – Windows Server 2012 R2”
There are numerous outstanding scripts, tools and resources located in the TechNet Gallery. In addition to MVPs and community members adding scripts, Microsoft also adds official contributions. For example, this is where you are downloading the Exchange 2013 Server Role Requirements Calculator and Exchange 2010 Server Role Requirements Calculator.
Since adding PowerShell scripts to this blog is no… Read the rest “TechNet Gallery Resources”
When migrating mailboxes from on-premises Exchange to Office 365, we can run into the error where the migration fails with an error stating that the target mailbox doesn’t have an SMTP proxy matching the Microsoft Online Routing Domain.
This can happen due to a number of causes. For example the mailbox is managed by an Email Address Policy (EAP) that was not updated with the online routing domain.… Read the rest “Office 365 Mailbox Migration – Target Mailbox Doesn’t Have An SMTP Proxy Matching”
It is possible to configure a “static” IP on your Azure IAAS VMs. This is something that we looked at in a previous post. One thing worth pointing out is that there is a little wrinkle with the current implementation, and you may run into unexpected results.
Static IP assignment in Azure VMs is not the same as configuring a typical static IP for a server in your on-pre… Read the rest “AzureVM Static IP Does Not Persist”
When creating a new Database Availability Group, there was a bit of rude shock when the installation failed. This customer had deployed multiple Exchange 2010 DAGs over the lifespan of the product, yet their latest build ran into an issue. They were able to create the DAG, but when adding the first mailbox server to the DAG, the operation failed.
This was not due to an underlying issue where the W… Read the rest “Add-DatabaseAvailabilityGroupServer – You Must Provide A Value For This Property”
