I need to view a .msg file. It is an email from Microsoft Outlook. How can I do this in Ubuntu?


Looks like the best thing to do is to convert them to an eml file using this script:


It's not pretty, it's not gui based, but it'll work.

    After installing the script as indicated (cpan -i Email::Outlook::Message) found a quick way to call it: creating a "Nautilus Script" with: #!/bin/bash for arg do msgconvert "$arg" done – Pisu Sep 30 '14 at 7:28

    I can install this on my computer with sudo apt install libemail-outlook-message-perl and then just msgconvert xyz.msg and I get a xyz.eml file – Jayen Feb 20 '19 at 10:56

Building on Martin Owens answer, this is the quick solution:

wget http://www.matijs.net/software/msgconv/msgconvert.pl
sudo apt-get install libemail-outlook-message-perl libemail-localdelivery-perl libemail-sender-perl
perl msgconvert.pl YourMessage.msg

    For Ubuntu 14.04 I also needed this package: libemail-sender-perl – bmaupin Nov 13 '14 at 14:08

Open it with MsgViewer http://sourceforge.net/projects/msgviewer/

wget -O MSGViewer.zip http://sourceforge.net/projects/msgviewer/files/latest/download
unzip MSGViewer.zip
cd MSGViewer-1.9
java -jar MSGViewer.jar

now, just drag'n'drop the msg file to the program window to have its contents displayed.

  • MSGViewer is a nice program, but I found that the viewer wouldn't open an attached .PDF file within the .MSG file. It appeared to change the filename to something that it couldn't find. – Mr Ed Apr 25 '16 at 7:21
  • This works nicely. However I have some problems with the encoding of non ASCI mails (in my case Greek). Do you happen to know if there is any setting for this. – Bruni Jun 22 '16 at 16:22
  • Worked for me great. – h22 Feb 9 '18 at 7:22
  • This works with Java 8. Java 11, that I tried with first, removed the java activation framework this uses and so no longer works without some extra effort to use the replacement github.com/eclipse-ee4j/jaf – jwd630 Oct 16 '18 at 1:49
  • Opening attached files (e.g. PDF files) worked fine for me after changing the OpenCommand from kde-open to xdg-open (MSGViewer setting). – nspo Sep 20 '19 at 14:43

I am on Ubuntu 15.10 and matijs'es msgconvert script seems to be available in the repos now. after running:

sudo apt-get install libemail-outlook-message-perl libemail-localdelivery-perl libemail-sender-perl

I can now now run

msgconvert *.msg

to convert the messages entirely with tools from the repos.

I found after install msgconvert that msgconvert wasn't installed when I ran the command. Rather than faff about trying to debug it, I did this. Done in less than a minute. http://www.zamzar.com/convert/msg-to-pdf/

    it doesnt handle attachments, so it's pretty fail imo – Northstrider Oct 3 '15 at 7:58
  • I converted from .MSG to .EML, and the attachments come through correctly. The .EML files was openable with Thunderbird. – Mr Ed Apr 25 '16 at 7:22

You can use ruby-msg ruby gem for that purposes. So:

  1. Install ruby and rubygems:

    # apt-get install rubygems gem
  2. Install the gem:

    # gem install ruby-msg
  3. Then use the "mapitool" utility:

    $ mapitool -i test.msg

    In some cases you can sporadically get the exception:

    /usr/local/share/gems/gems/ruby-msg-1.5.2/lib/mapi/mime.rb:109:in `join': incompatible character encodings: UTF-8 and ASCII-8BIT (Encoding::CompatibilityError)

    So just fix the following file lib/mapi/mime.rb with the following regexp:

    sed 's/part.to_s(opts)/part.to_s(opts).encode("UTF-8", :invalid=>:replace, :undef => :replace, :replace => "")/' -i /usr/local/share/gems/gems/ruby-msg-1.5.2/lib/mapi/mime.rb

    Where do you see that seamonkey is able to view those files? Add a detailed description please. – guntbert Mar 19 '15 at 14:10
  • Please install this program, after that from "File" menu choose "open file..." and choose your .msg file. – Davidgh Mar 19 '15 at 14:16
