I just had a Teams call with a customer to resolve a strange mystery about Azure MFA.
The customer called me and explained, that he has a user with Azure Multifactor Authentication (MFA) disabled, but when he logs in with this account, he is asked to setup MFA. He setup MFA and was able to login according to their Conditional Access policies.
The customer and I took a look into their tenant and checked a couple of things.
There are still customers out there that are running vCenter Server on a Windows host. This year, despite the fact that most customers have set project on hold, I managed some of them to migrate to a vCenter Server Appliance.
Some days ago I had an meeting with one of my favorite customers to migrate their vCenter Server 6.5 to a vCenter Server Appliance 6.7 U3l. They were still on 6.
One of my customers purchased a bunch of Microsoft 365 subscriptions in order to use them with Office 365 and Windows 10 Enterprise. The customer called me because he had trouble to activate the Windows 10 Enterprise license.

I would like so summarize some of the requirements in order to successfuly active Windows 10 Enterprise subscriptions.
License First of all, there is a licensing requirement. You need at least a Windows 10 Pro or Windows 10 Pro Education.
We have to deal with COVID19 for a year now and from the IT perspective, 2020 was a pretty strange year. Many project were not cancelled, but were placed on-hold. But two kinds of projects went through the roof:
Microsoft 365, and Horizon View As you might noticed I blogged a lot about Exchange, Exchange Online and Horizon this year. The reason for this is pretty simple: That was driving my business this year.
December 31, 2020 will not only be the end of the miserable year 2020, it will also be the end of an era - the era of Adobe Flash! Adobe has announced that they will stop supporting Adobe Flash after December 31, 2020. Furthermore, Adobe will block Flash from running in Flash Player on January 12, 2021. Adobe strongly recommends that all users immediately uninstall Flash Player. I got a popup a couple of times, asking me if I want to uninstall Adobe Flash.
While migrating a customer from Exchange 2010 to Exchange 2016, I had to create an Exchange Hybrid Deployment, because the customer wants to use Microsoft Teams. Nothing fancy and I’ve did this a couple of times.
Unfortunantely the Hybrid Connection Wizard failed to create the migration endpoint. A quick check of the logs showed this error:
Microsoft.Exchange.MailboxReplicationService.MRSRemotePermanentException: The Mailbox Replication Service could not connect to the remote server because the certificate is invalid.
A couple of days ago, I wrote about our first steps to move our on-prem stuff to Azure. This post will cover how we adopted Office 365 and how we have started with our Azure deployment.
Our first step into Office 365 was Microsoft Teams. We needed a solution for calls (audio/ video) and chat. We skipped Skype 4 Business and started with Microsoft Teams.
Our Microsoft Teams deployment was pretty simple: We used our Microsoft IUR Office 365 E3 plans.
During the deployment of a vSAN cluster consisting of multiple HPE ProLiant DL380 Gen10 hosts, I noticed a memory health warning after updating the firmware using the Support Pack for ProLiant. The error was definitely not shown before the update, so it was clear, that this was not a real issue with the hardware. Furthermore: All hosts showed this error.

The same day, a customer called me and asked me about a strange memory health error after he has updated all of his hosts with the latest SPP…
As part of an ongoing Exchange 2010 to 2016 migration, I had to replace the self-signed certificate with a certificate from the customers PKI. Everything went fine, the customer had a suitable template, we’ve added the necessary hostnames and bound IIS and SMTP to the certificate. The mess started with an iisreset /noforce…
The iisreset took longer than expected. After that, I tried to login into the ECP, entered username and password and got an error.
It was a bit quiet here due to the current COVID 19 pandemic. But now I’m back with a pretty interesting story on how my colleagues and I moved most of our on-prem server stuff to Microsoft Azure and Office 365.
It all started with the COVID19 lockdown in Germany in March 2020. We moved into our home offices after setting up a small VMware Horizon View deployment to access our PCs using physical View Agents and manual desktop pools.
