Office365 – Distribution list blank return path

When you are using Office365, you may find that external email addresses in a distrbution list do not recieve mails sent to the distribution list email address.

Many spam filters will block emails with a blank or empty return path, but Office365 sets this blank as default, to prevent email bounce loops.

This is normal behaviour – a large distribution list shouldn’t distribute a bounce/DSN report to the entire membership.

For a single membership list for use with Zendesk, Help Scout or other similar mailbox monitoring applications, it may be necessary.

Here is how to enable the return path for a distribution list:

Connect to Office365 with PowerShell:
$LiveCred = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $LiveCred -Authentication Basic -AllowRedirection
Import-PSSession $Session

Check to see which return paths are enabled/disabled:
Get-DistributionGroup <Name Of DL> | fl *report*

When running this command, you should see:
ReportToManagerEnabled : False
ReportToOriginatorEnabled : False

Enable return path to originator if disabled:
Set-DistributionGroup <Name Of DL> -ReportToOriginatorEnabled $true

When the command is run again:
Get-DistributionGroup <Name Of DL> | fl *report*

You should see:
ReportToManagerEnabled : False
ReportToOriginatorEnabled : True

Disconnect from the Office365 server:
Remove-PSSession $Session

You will then have a populated return-path (with the email address of the distribution list).

Office 365 – Set the default domain

When you first setup Office365, Microsoft provides you with a default domain – usually – for example, the Jaytag domain is

This can cause a small headache – as it’s not obvious when you have added your companies domain where to set this as default – so when you add new users, the primary email address will be

To set the default domain to the domain you have added, login to Office365 and click into the adminin

Click on your company name in the top-left corner of the administration interface.

Then click on Edit in the top-left corner of the company window.

Windows XP Recovery Console – KB310994 download

To manually install the Windows Recovery Console, you have to have the necessary updates. It seems Microsoft have removed the link to the recovery console that used to be linked to from here.

This makes running tools like ComboFix for example, quite difficult.

I’ve sourced the files (at least for SP2 and up) they are mirrored here:
windowsxp-kb310994-sp2-home-bootdisk-enu.exe – For Windows XP Home SP2 and newer.
windowsxp-kb310994-sp2-pro-bootdisk-enu.exe – For Windows XP Professional SP2 and newer.

To install for combofix use, you can download the file to your PC and drag and drop onto the combofix.exe file, as detailed here.

Sporttracks v2 – Map problem fixed

With Sporttracks v2, there is an issue that the Terraserver map plugin no longer functions correctly. Maps cannot be zoomed, and over time, none of the routemaps appear to display at all.

Thankfully, there is a user created plugin called Apply Routes.

Apply Routes provides a number of extensions to the SportTracks functionality:

  • It adds a number of MapProviders (google, microsoft, openlayers, geoportail)
  • It allows 3d Simulation of your workouts
  • It has a number of features for modifying activities
  • Adding a gps track to a workout that doesnt have one
  • Joining workouts
  • UpdateHistory – Bulk updates to your logbook.

The plugin for Sporttracks v2 can be downloaded here. (get the .st2plugin file).

Once the plugin is installed, selecting a different map (the blue dropdown arrow in the ‘Route’ window) will show the correct map underneath your activity route.

Sporttracks v2.1 – Download here

Sporttracks is an excellent piece of software if you like to keep a record of your performance, training or fitness over time.

Version 3 of the software was released back in September 2010, and it’s very, very good. However, it does cost $35 after a 30 day trial.

I’ve been happily using Sporttracks v2 for some time (although the mapping is now quite flaky…). I had to reinstall it recently, and found it hard to find.

So, its mirrored here (link removed at request of Zone Five, there are plenty of other sources for the file if you google the exact filename – Setup_SportTracks_2.1.3478.exe)

Google link here.

You can download version 3 of the software at the Zone Five website here.
