When troubleshooting cross-premises calendar availability issues, it can be useful to know the name of the local on-premises endpoint which is used. By knowing the path and URL, you can then search the IIS logs for the path.
This will accelerate finding the correct entry(ies) and assist with troubleshooting.
The full listing of Hybrid deployment prerequisites is available on Docs.
Perhaps the best thing to come to Exchange over the last 10 years was the Hybrid Configuration Wizard (HCW). While many take this feature for granted, if you had to manually deploy Exchange 2010 SP1 hybrid to Exchange Online you will shudder at the mention of the Service domain. But let’s not dredge up those memories…
Recently an update was released to the HCW, and initially the update looke… Read the rest “Beware the Exchange Hybrid Configuration Wizard Doppelganger”
When deploying Exchange hybrid, one of the aspects that can prove to be the most challenging is Exchange Online mailboxes trying to view calendar information for on-premises mailboxes.
This is because there are multiple potential issues which can be caused due to management of Exchange on-premises, firewall rules and reverse proxy configuration issues. What was slightly interesting with this custo… Read the rest “Previously Working Now Unable To See Exchange On-Premises Free/Busy – Redux”
For various reasons, the aforementioned Remove-HybridConfiguration cmdlet has been something that has been something I've had to review recently.
This cmdlet is not present in Exchange 2010, it is only available in newer versions of Exchange. For example if we try to find this cmdlet on an Exchange 2010 server, it is not present.
Only the Get, New, Set and Update-HybridConfiguration cmdlets are avai… Read the rest “Remove-HybridConfiguration Cmdlet”
Exchange 2019 CU6 has been released to the Microsoft Volume Licensing Center! Exchange 2019 has a different servicing strategy than Exchange 2007/2010 and utilises Cumulative Updates (CUs) rather than the Rollup Updates (RU/UR) which were used previously. CUs are a complete installation of Exchange 2019 and can be used to install a fresh server or to update a previously installed one. Exchange… Read the rest “Exchange 2019 CU6 Released”

This is one of those older documents, that for many reasons I seem to keep coming back to over the years. Even as we transition away from classic Outlook Anywhere to MAPI/HTTP, knowing some of the features/limitations of Outlook Anywhere and why MAPI/HTTP is a better replacement is something that will be around for a long time to come.
Since TechNet is dead, even though I know exactly what I'm loo… Read the rest “Exchange 2007 Outlook Anywhere White Paper”
The below are some of the older Office 365 welcome pages, thought it might be fun to make the screenshots available for reference. They are from an old blog post that never made its way out of the draft folder. So it was repurposed for this post.

When reviewing a customer’s Exchange server to appraise the current state of their certificates, they saw an "unexpected" certificate on the Exchange server.
The below is an Exchange 2010 SP3 RU24 server with a repro of the issue. There was nothing wrong, but the reason for seeing the additional certificate was not readily apparent to them.
The customer was looking in Exchange Manag… Read the rest ““Unexpected” Exchange Certificate”
Managing and maintaining an Exchange server requires multiple actions. Not only do the Exchange CU and security updates need to be installed along with the Windows OS updates, it is also required to update and maintain the .NET Framework. This is not a new requirement, and has been a required task for many years now. With that being said, there is now a tighter requirement and is enforced by Ex… Read the rest “Expediting NET Framework Install For Exchange”
