This is a link throw-down for the items that we discussed during a recent Office 365 workshop that I delivered to customers in sunny Calgary.
I’m posting the links here since they will be available to all of the attendees, and thought that others may also find them useful/interesting.

This post was promoted from the draft bin to production after a customer visit a couple of weeks ago. When onsite we were looking at how the environment was configured. The admins had written a series of scripts to determine the environment state which was excellent to see! One thing that they had assumed though was that the ServerName attribute on a mailbox was where the database was currently … Read the rest “Exchange ServerName Points To Wrong Or Decommissioned Server”
In some of the recent posts you will have noted that there have been some issues with VMware, and also network cards dropping packets in packets received discarded. One symptom of this is that nodes will be removed from the cluster and EventID 1135 is logged into the System log. EventID 1135 states that the Cluster node was removed from the active failover cluster membership. In Exchange 2010/2… Read the rest “Retrieving Cluster Error 1135 From Servers”
In the November 2014 security bulletin there were 14 updates released. The updates resolved security issues in IE, OLE and Schannel. It is the latter that is worth calling out for attention since this is the basis of the Microsoft implementation of SSL. Exchange makes heavy use of SSL, and is typically connected to the Internet.
You can read about the other security details in the security bullet… Read the rest “Critical Schannel Vulnerability – MS14-066”
When we are performing the Exchange Risk Assessment, one of things PFE love to check is how servers have been configured for IPv6. There have been numerous occasions where we have found servers whose admin has said that they have disabled IPv6, but when you look at the server it is not really disabled.
When we take a look at the Exchange server, the initial clue is that the network card’s TCP/IPv6 … Read the rest “Disabling IPv6 And Exchange – Going All The Way”
Generally the Exchange external Autodiscover DNS entity is configured as a regular A record. Sometimes a service record (SRV) is used instead. Since I have the habit of forgetting the syntax of quickly querying for the SRV record, this is one of those shared bookmark posts!
Nslookup is the tool of choice here! Its documentation can be found on TechNet.
There are two ways to run nslookup – interac… Read the rest “How To Check Exchange Autodiscover SRV Record Using Nslookup”
Imagine the scenario -- all is working well with your Office 365 hybrid solution until you come into the office tomorrow morning and you get calls saying on-premises users are unable to see the free/busy information for mailboxes in Office 365. While this sounds like a bad dream, this reality could come true tomorrow morning, so let’s to check to make sure that this does not happen!
The background… Read the rest “Awareness – Is Your Federation Trust Metadata Updated?”
Previously we discussed an interesting feature of the Exchange virtual directory cmdlets where they check data stored in AD, rather than making a trip to the server and querying its IIS metabase. For the details on this, please read the original post here: Slow Response To Exchange Virtual Directory Cmdlets.
In that article we were using the ADPropertiesOnly switch so that it was very quick to… Read the rest “Using ADPropertiesOnly With Exchange Virtual Directory Cmdlet Shows False Positives”
Please be aware of an emerging issue in Exchange 2013 and Exchange Online. In a delegate scenario it is possible that OWA can be used to delete a folder from the other user’s mailbox and not appear in the Deleted Items section of the recoverable items folder.
This is covered in KB 2996477 -- Folder deletions are not preserved for mailboxes put on litigation or in-place hold in Ex… Read the rest “Awareness – Litigation Hold Or In-Place Hold Folder Deletions Not Preserved in Exchange 2013 OWA”
