Importing EML files (or Outlook Express DBX) into Outlook 2010

25 Mar 2011

There are some documented ways of exporting Outlook Express emails to Outlook 2010. One major problem with this migration, is that you need to have both Outlook Express and Outlook 2010 installed on the same machine. If you have installed Outlook 2010 on a fresh Windows installation it could even be impossible to do, since Outlook Express cannot be installed on x64 Operating Systems.

If you don’t have both on the same machine, the alternative proposed solution is to import your EBX mailboxes from Outlook Express to Windows Live Mail first, and then exporting from Windows Live Mail to Outlook 2010.

Having been through that, I can tell you that this method is a pain in the ass. First of all, I noticed that many emails from Outlook Express were not being copied to Windows Live Mail. Next, I realized that even the emails which were appearing in Windows Live Mail could not be exported to Outlook 2010, failing with a MAPI error, and as far as I researched there is no fix available for 64-bit systems.

Having said that, I found this Portable Outlook Express Message Extractor, a nice freeware utility which could export EML files from Outlook Express. According to my tests, all emails have been exported, which proved to be better than Windows Live Mail importing.

After having exported EML files, all of them grouped in windows folders which mimic the same folder names of Outlook Express, I needed to found something to import those emails to Outlook.

I found some shareware programs that are supposed to import EML files into Outlook 2010, but I was very surprised that Outlook doesn’t have this as native feature.

Instead of buying the shareware, I decided to create my own VBA macro for that, since I have large VBA programming background. To my surprise, although Outlook can open EML files, there is no way to do it programatically only with VBA. So I created this VBA macro which loops through some folder, and opens each EML file by using SHELL EXEC. It may take a few milliseconds until Outlook opens the EML file, so the VBA waits until something is open in ActiveInspector. Finally, this email is copied into some chosen folder, and (in case of success) the original EML file is deleted.

This macro crashes sometimes, but you can restart the macro at any time, and it will restart from where it previously crashed (remember, all successfully imported EML files are deleted). If it keeps crashing after restart, then probably there is a problem with the next EML file which is about to be imported. In this case you can just delete the problematic EML.

PS: Sometimes you can open the EML yourself, without crashing Outlook, but according to my tests, everytime that a EML file was crashing Outlook it was something unimportant, like read receipts.

How to Run VBA Code in Your Outlook

At times you may wish to utilize VBA code in Outlook to achieve more functions. Yet, you do not know how to run VBA code in your Outlook. Thus, this article will expose the detailed steps to you.

Thereinafter, we will take Outlook 2010 version as an example and show you the elaborate steps, ranging from modifying macro security settings to running VBA code. Now, read on to get them.

Step 1: Enable “Developer” Tab

1. First of all, after launching Outlook, access “File” menu.
2. Then, in “File” menu, select and click on “Options”.
3. Next, in the popup “Outlook Options” window, switch to “Customize Ribbon”.
4. Later, on the right side, you can find out and enable the “Developer” tab.
5. Lastly, click “OK”.

Step 2: Check Macro Security Settings

1. After returning to Outlook main window, you can access “Developer” ribbon.
2. Then, click on the “Macro Security” button.
3. In the subsequent screen, you should select “Notifications for all macros” and hit “OK” button.

Step 3: Access Outlook VBA Editor

To run VBA code, you have to access the VBA editor firstly, which can be achieved by the following 2 means:

1. In Outlook, under the “Developer” tab, click on the “Visual Basic” button.
2. Or you can directly press “Alt + F11” key buttons.

Step 4: Add VBA Code

1. In VBA editor, namely “Microsoft Visual Basic for Applications” window, you need to expand the “Microsoft Outlook Objects” folder on left side
2. Then, double click on the “ThisOutlookSession” project to open it.
3. Subsequently, you can copy and paste your VBA code into the white editing pane of this project.
4. Optionally, you can copy the VBA code into a module.

• Click “Insert” button in the menu bar.
• Choose “Module” from the drop down list.
• Then, a new module will display. Now you can copy code into the module as usual.

Note: In general, you can paste the code into either “ThisOutlookSession” or a module. But, the VBA code involving events, like “Application_Start”, must be put in “ThisOutlookSession”.

Step 5: Run VBA Code

After adding the macro, you can run it. In the macro window, you can press “F5” key button or click on the “Run” button in the toolbar.

Note: For the VBA code involving events, like “Application_Start”, you ought to restart your outlook to activate it.

Optional Step: Add Macro to Quick Access Toolbar or Ribbon

If you would like to run macro in the main Outlook window instead of in the VBA editor, you can add the macro to Quick Access Toolbar or ribbon.

Add Macro to Quick Access Toolbar

1. First off, access “Outlook Options” by following the operations shown in Step 1, in which you can shift to “Quick Access Toolbar” tab.
2. Next, select “Macros” from the “Choose commands from”.
3. Then, in the macro list, choose a macro.
4. After that, click “Add >>” button in center.
5. Finally, click “OK”.
6. Since then, to run this macro, you can simply click the macro button in Quick Access Toolbar.

Add Macro to Ribbon

1. At first, go to “File” menu and click “Options”.
2. In the subsequent “Outlook Options” window, turn to “Customize Ribbon”.
3. Then, on the right side, click “New Group” button.
4. Next, click “Rename” button.
5. In the popup dialog box, specify a name and icon for the new group, such as “Smart Move” in my instance, and click “OK”.
6. Later, on the left side, select “Macros” from the drop-down list of “Choose Commands from”.
7. After that, in the macro list, select the macro you want.
8. Then, click “Add >>” button in center to add this macro to the custom group.
9. Next, click “Rename” button.
10. In the new dialog box, change the name of this macro and assign an icon to it.
11. Ultimately, click a series of “OK” until getting back to Outlook main window.
12. Now, you will see the new macro button in ribbon, as shown in the following screenshot.

I have this error, when try to run it.

In what context are you running the script? The script requires the Outlook namespace, so it should be run in Outlook VBA editor. I have added a how-to for you to make sure you're in the right environment.

Just wanted to add another comment thanking you for both taking the time to create and post this. I'm using a modified version without the subfolder functionality, as I just wanted it all in a single Archive, but you'd done 99% of the work for me which is never a bad thing!

Thanks again.

Great script very helpful. It is the best alternative to pay for any tool online.
