Unable to Remove Exchange 2010 Public Folder Database

Posted on 30th September 2020 by Rhoderick Milne [MSFT]

One of the last rites of removing Exchange 2010 will be to remove the its legacy public folder database after the content has been moved to either shared mailboxes or to modern public folders. Maybe you just decide to delete those Christmas party pictures from 1999 as an alternative to carrying the legacy content forward...

However deleting is simpler said than done. For many years the project to… Read the rest “Unable to Remove Exchange 2010 Public Folder Database”

QuickTip – Which Managed Availability Components Are Unhealthy?

Posted on 28th September 2020 by Rhoderick Milne [MSFT]

Exchange 2013 introduced the Managed Availability feature, so Exchange can self monitor and perform recovery actions upon itself. While this has greatly helped Exchange become more self-healing, one of the downsides is that there is no real UI for Managed Availability. The only UI is the Managed Availability Event Logs. All of the configuration inside of Exchange is done using PowerShell. The … Read the rest “QuickTip – Which Managed Availability Components Are Unhealthy?”

Beware the Exchange Hybrid Configuration Wizard Doppelganger

Posted on 27th July 2020 by Rhoderick Milne [MSFT]

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”

Unable to Edit WAP Published Application in Mixed Mode Farm

Posted on 24th July 2020 by Rhoderick Milne [MSFT]

During the upgrade process it is expected that there will be multiple versions of AD FS and WAP servers operating in a farm at a given time. This is actually a good option as it allows us to easily upgrade from AD FS 2012 R2 to a newer version such as 2016 or 2019. We can do this without having to build a brand new farm from scratch and then cutting over applications to the new farm wi… Read the rest “Unable to Edit WAP Published Application in Mixed Mode Farm”

Previously Working Now Unable To See Exchange On-Premises Free/Busy – Redux

Posted on 18th July 2020 by Rhoderick Milne [MSFT]

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”
