Fix to outlook freezing while reading paypal emails

A recent change in the PayPal notification messages can cause Outlook to hang for a couple of minutes. The issue is caused by an invalid picture reference in the message and the way Outlook deals with time-outs.


Background information

At the bottom of the message, there is a hidden tracking image. Instead of this image pointing to a web server, it is pointing to a non-existing network share. As it is pointing to a network share and not to a web server, Outlook’s “Internet picture blocking” functionality doesn’t kick in and tries to retrieve the content.

Obviously this fails, but Outlook is quite persistent in still trying to reach this network share and it takes up to a minute for it to time-out and stop trying. As this is being done in a foreground thread, it means you cannot use Outlook during this time and will display a “Not Responding” message in the title bar when you try it anyway.
Fixing the broken messages

PayPal is aware of this issue and the template should be corrected soon (if it hasn’t been already). As long as it hasn’t been fixed, you can disable the Reading Pane to prevent accidental selection of the message and cause another time-out of a minute.

As the issue is within the message itself, the issue won’t go away for PayPal messages which you have already received. Throwing away the broken messages would be one solution but if you need to keep the message, you can do the following;

Disconnect yourself from the network by either unplugging your network cable, disconnecting yourself from the wireless network or by disabling your network adapter.
Open the message in its own window via a double click; this should go quickly now.
Place the message in Edit Mode;
Outlook 2003
Edit-> Edit Message
Outlook 2007
tab Message-> group Action-> Other Actions-> Edit message
Outlook 2010
tab Message-> group Move-> Actions-> Edit Message
If you get a prompt that Outlook will need to download external content, accept it. As you are disconnected, it won’t actually attempt to download anything.
At the bottom of the message, you’ll see an e-mail reference number from PayPal. Note the space behind the last number.
Place your cursor after this space and press Backspace twice.
Or place your cursor directly after the last number of the reference number and press Delete twice.

The first time you press it, you’ll select the image which will show as a dot (see screenshot below).
The second time you press it will actually remove the image.
Save and close the image.
Reconnect to the network.

Remove the space behind the reference number to select the image, which
will show as a dot. Pressing Backspace again will remove the broken image.
Fixing a lot of broken messages at once

If you have a lot of broken PayPal message which you all need to keep, then you can also modify your HOSTS file to fix the issue.

Start Notepad as an administrator.
You can do this by right clicking on the Notepad shortcut in the Start Menu and choosing “Run as administrator”. If you don’t see this option, hold SHIFT while right clicking on it.
Choose File-> Open… and open the following file;
C:\Windows\System32\drivers\etc\hosts
Add the following line at the bottom.
127.0.0.1 102.112.2o7.net
Save the file and close Notepad.

Now all the bad requests for the tracking image will be directly rerouted back to your computer which rejects it and causing a time-out which is hardly noticeable.
