Exchange 2013 Initial Configuration Settings: How to configure a Postmaster address (part 8)

Exchange 2013 logo

In this post I’ll look at how to configure a postmaster address for our Exchange Organisation.

The postmaster address is used for non-delivery reports (NDRs) sent to recipients outside of your Exchange Organisation and is specified in RFC 2821.

In Exchange 2013 the external postmaster address is blank by default. This has the effect of the external postmaster address being postmaster@YourDefaultAcceptedDomain.

It can be useful to create a postmaster mailbox, or assign the email address to an admin mailbox so that recipients can reply to NDR messages for assistance. Anyone who is familiar with NDRs will appreciate they are far more useful to admins than they are to end users! The downside of this though is as it’s a well known address it can be open to abuse and spam.

Exchange 2013 Cumulative Update installation tips and best practices

Exchange 2013 logo

Edit: The latest update is now Exchange 2013 Cumulative Update 18. See here for a list of all updates and KB articles.

I’ve got a few Exchange 2013 installations in production now so I thought it was about time I wrote a post on best practices when installing Exchange 2013 Cumulative Updates and Service Packs.

Each Cumulative update is a version of Exchange in it own right. Therefore if you are installing a new deployment of Exchange you can install straight from latest Cumulative Update, which at the time of writing is CU11 (released December 2015). KB3099522 contains a list of fixes and enhancement for CU11. Check here to see what the current latest version is.

This also means that once installed you cannot uninstall a Cumulative Update, if you do you uninstall Exchange.

The update is approximately 1.6GB in size and can be downloaded from here.

In my test lab with a single Exchange server and single Domain Controller the update took an 60 minutes to install.

The official Exchange Team blog post can be found here.

Exchange 2010 SP3 Update Rollup 12 released and installation tips

Microsoft Exchange 2010 SP3 Update Rollup 11 Installtion tips

Edit: Update Rollup 18 is now available for Exchange 2010 SP3 see the post Exchange 2010 SP3 Update Rollup 18 installation tips.

On 15th December Microsoft released the Exchange 2010 SP3 Update Rollup 12.

I installed Update Rollup 12 on my test SBS 2011 server this evening and it took 28 minutes from start to finish, so I wouldn’t expect it to take much longer than this in production.

The new update was released today so please test before installing into your production environment. Maybe even wait a few days or a week or two to make sure the QA is up to scratch on it.

For migrations to Exchange 2016, Exchange 2010 SP3 Update Rollup 11 is the minimum version that will be supported in a coexistance environment.

In the demo environment no previous versions of Exchange have been installed so we are setting up everything from scratch.

Exchange 2013 Initial Configuration Settings: Setting SMTP accepted domains (part1)

Exchange 2013 logo

Following on from previous posts on How to install Exchange 2013  SP1 and Exchange 2013 Initial Configuration Settings, in this first part of a series of posts I’ll look at setting the SMTP accepted domain.

By default when you install Exchange 2013 the default accepted domain will be the fully qualified domain name of the Active Directory domain you installed the server into.

In my demo environment the AD domain is, so the default accepted domain is Obviously we want to remove the ad part of the address to hide the internal ad structure and make the actual email address more useable, so let’s look at adding another accepted domain.

Exchange Admin Center - mail flow - accepted domains

Exchange 2013 Initial Configuration Settings: Setting email address policies (part 2)

Exchange 2013 logo

Following on from the previous post Exchange 2013 Initial Configuration Settings: Setting SMTP accepted domains (Part 1) , in this second part of a series I’ll look at setting up an email address policy.

Until you create a new email address policy any recipients (users, resources, contacts, groups) you create will get their email address from the default email address policy. Therefore we’ll create a new email address policy with settings that we want before creating new recipients.

Another reason for having it in place before you create recipients is in large environments applying an email address policy can take a long time depending on the number of recipients it effects.
