Troubleshooting Problems Opening MSG Files

Issues Opening MSG Files

Microsoft Outlook Express Removed

You encounter an error message such as "%%os%% Can't Open MSG Files" when trying to open your MSG. When this happens, it is commonly due to Microsoft Outlook Express missing in %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: When another MSG application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Outdated Microsoft Outlook Express

Sometimes your installed version of Microsoft Outlook Express won't support your Saved Email Message file. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Outlook Express. Most of the time your Saved Email Message file was created by a newer Microsoft Outlook Express than what you have installed.

Tip: Sometimes you can get a clue about the version of MSG file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Conclusion: The majority of MSG file opening issues are due to not having the correct Microsoft Outlook Express version installed.
