I know that sound like a weird title right? How can you leverage Microsoft Online Subscriptions on-premises? After all Office 365 is in the cloud? What is not obvious is that a number of the subscriptions actually do grant you usage rights that are for on-premises use cases! The key document to refer to is the […]
Free Windows 10 upgrade offer via CSP
Most of us know that there was an offer from Microsoft to upgrade from Windows 7 and 8.1 back in 2016, however most of us don’t know that you can still get a ‘free’ upgrade today! Microsoft announced a new offer in January 2017 for any customers who have a Windows 10 Enterprise subscription via […]
Exchange Resource Mailboxes – Part 1
Since Microsoft Exchange 2007 Resource Mailboxes have been a feature of Microsoft Exchange. Overall it appears that Room and Resource mailboxes are a feature that has matured over the previous versions of Microsoft Exchange Server and now receive just a few minor improvements to make them simpler to manage. IBM’s Domino platform has always had […]
Exchange Federation to Office 365 without Hybrid
Exchange Federation has been around a long time, but of course more recently any time you talk about integrating with Office 365 people start going down the hybrid route. What if you don’t want hybrid though, what if all you want is to be able to share free/busy information? Let’s set the scene. We have […]
Windows Firewall not writing to its logfiles
As part of Group Policy Management guidelines from the Centre of Internet Security (CIS), the recommendation is to turn on Firewall logging on all Windows Servers, and to save each profile to their own log file. Configuring this in Group Policy is pretty straight forward. Just type in the new file name for each profile, […]

The Microsoft Account Dilemma
For about 18 months now I have been in a world of pain. Up front I want to say that Microsoft do an incredible job at this really. This is complicated stuff I am sure, connecting all these disparate systems, migrating and consolidating. I think where they have gone wrong is that by trying to […]
Microsoft Changes MCSE/MCSD… again…
As you will probably know, a few years ago Microsoft changed MCSE so that the qualifications would no longer have a version number in the name but instead they required a recertification every three years. This was good on one hand since it avoided you needing to change your CV, however it did mean enforced […]
Domino SMTP connection round robin
Domino has its own internal processing or ideas on how it implements TTL for DNS entries on SMTP Connection documents (where “Connection type:” is SMTP), which is frustrating as it doesnt always conform to what is out in the wild which you have diligently configured in DNS. Therefore if you are attempting to transfer messages over […]
Office 365 Tenant to Tenant Migration
Last weekend I undertook a Migration from one Office 365 tenant to another – manually. Whilst we normally work in the enterprise space migrating thousands of users, this was a special case project undertaken deliberately as a manual process end to end. It wasn’t without issue and hiccups, made more worrying because it was for […]
