This release of Microsoft Internet Explorer/Outlook Express
4.01 for Sun Solaris includes support for IMAP functionality
(IMAP4) in Outlook Express, performance improvements, and
fixes for known Year 2000 problems.


To run this version of Internet Explorer/Outlook Express
4.01 for UNIX, your system must meet the following minimum
* A Sparcstation 2 or greater
* US English Solaris 2.5 or above
* 32 MB of RAM (64 MB recommended)
* 65 MB of hard-disk space to perform the installation


Downloading Internet Explorer/Outlook Express 4.01

You can download the file ie4setup from the following FTP

The product is also available at the following HTTP site:

The file ie4setup is a self-extracting executable that
contains all the files you will need. If you ftp this file,
be sure to use binary transfer mode.

Installing Internet Explorer/Outlook Express 4.01

Installing to the default directory, /usr/local/microsoft,
may require that you be logged in as root.
1) Change directory to where you downloaded the file
   ie4setup: 'cd <download directory>'.
2) Make the downloaded file executable: 'chmod +x
3) Run the executable: './ie4setup'.
4) When Setup prompts you for an installation directory,
   you can accept the default directory or type in a new
   directory path.

To run Internet Explorer 4.01:

After it is installed, you can start Internet Explorer by
running "<installation directory>/bin/iexplorer".

To run Outlook Express 4.01:

After it is installed, you can start Outlook Express by
running "<installation directory>/bin/oexpress".

NOTE: Internet Explorer and Outlook Express 4.01 introduce
new features that may not compatible with earlier releases
of our product. We recommend that all platform installations
be upgraded to the same revision of the product.

Uninstalling Internet Explorer/Outlook Express 4.01

You must remove the current installation directory, for
example, 'rm -r /usr/local/microsoft'. Additionally, each
user that has run either Internet Explorer or Outlook
Express will have a directory named ".microsoft" in the home

directory for the user account.  This directory contains
customer user settings and my also be deleted if
the user wishes to remove all personal settings for Internet
Explorer and Outlook Express (including the private message
database and favorites folders).

If you implemented CDE integration as explained below, you
should remove it by deleting the "IE4.dt" file from the
system or user directory.


If you run Internet Explorer within a CDE session, it will
adopt the CDE color scheme unless overridden with explicit
color settings.

If you install Internet Explorer on Solaris 2.6, you will be
asked whether you wish to install CDE integration.  If
you answer yes, a file called "IE4.dt" will be added to the
system.  If you are user "root", the file is added to the
directory /etc/dt/appconfig/types/C, and will affect all
users on the system.  Otherwise, the file will be added to
the directory ~/.dt/types, and will affect only you.

The file "IE4.dt" is in the "ie4" subdirectory of the
installation, and can be copied to other users' ~/.dt/types

If you use CDE integration, then the generic web browser
icon will launch Internet Explorer, and the default action
for an HTML file will be to launch Internet Explorer and
open the file.

CDE integration can be removed by simply deleting the
"IE4.dt" file from the system or user directories, and
restarting the session.

There is a set of Internet Explorer icons for use with CDE,
in the ie4/ie4icons subdirectory of the installation. They
can be used by administrators who want to place the Internet
Explorer logo on the desktop.

More information about the integration can be found in the
Knowledge Base article Q181622 available from


The User Agent String for Internet Explorer is static except
for the third field which depends on the Operating
System and the processor you are using.

Here are some common configurations and the user agent
strings generated by Internet Explorer on these platforms:
   Sparc 5, Solaris 2.5.1:
      Mozilla/4.0 (compatible; MSIE 4.01; SunOS 5.5.1
      sun4m; X11)
   Any Ultra, Solaris 2.5.1:
      Mozilla/4.0 (compatible; MSIE 4.01; SunOS 5.5.1
      sun4u; X11)
   Any Ultra, Solaris 2.6:
      Mozilla/4.0 (compatible; MSIE 4.01; SunOS 5.6 sun4u;


In addition to being able to organize favorites through the
Organize Favorites item on the Favorites menu, you can also
manipulate your favorites through the file system.  Your
favorites are organized and maintained in the directory,
~/.microsoft/Favorites. You should shut down Internet
Explorer to make changes to this directory.  The changes
you make will be reflected in your Favorites menu when you
restart Internet Explorer.


Solaris Compatibility

Internet Explorer is not supported on Solaris 2.4 and below.

To run Internet Explorer on Solaris 2.5 a patch is required.
Use of any or all of these patches is subject to
any license terms that may accompany the patch.  Patch
103093-23 corrects a multithreading issue.

NOTE:  Additional patches from Sun Microsystems, Inc., may
be necessary to get full functionality from this patch.
See the patch's README for more details.

   A link to download this patch is available from the
   following page:

   If that link doesn't work, try the FREE PATCHES link off

   You can download either the patch itself at:

   There is also a cluster of recommended patches that will
   install in a single step which includes 103093-23:

   Note that this patch number may become 103093-24 or
   higher in the future as Sun Microsystems, Inc., upgrades

Internet Explorer will not start on a Solaris 2.5.1 system that has been
updated with the Xsun patch 103566-34 or 103566-35. This is due to problem
number 4152947 in the Sun patch. Please obtain version 38 or 39 of this
patch to address this issue.

If you install Internet Explorer on a host machine, and use
NFS to mount the installation on another machine using a
different pathname, then you will not be able to execute
Internet Explorer on the second machine. Similarly, if you
move the installation directory to a different pathname,
you will not be able to execute Internet Explorer. In both
cases you will receive the following error message:

  Support for SunOS 2.6 has not been installed on this

  The message may read "SunOS 2.5" or "SunOS 2.5.1" as


To fix the problem, ensure that the environment variable
MSFT_HOME is set to the name of the installation directory
before starting Internet Explorer.  For example, if you
mounted or renamed the installation directory as
/net/myhost/local/ms, then execute this

   (csh) setenv MSFT_HOME /net/myhost/local/ms/ 
   (sh) MSFT_HOME=/net/myhost/local/ms/ ; export MSFT_HOME

Note the trailing "/" character.

You may use alternative approaches. For example, experienced
users may prefer to make a copy of the
"bin/iexplorer" and "bin/oexpress" commands, which are
simple shell scripts, and change the directory reference on
line 3.

If you have multiple platforms installed in a single
directory, you should set the environment variable
MSFT_HOME to the name of the installation directory before
starting Internet Explorer or Outlook Express.

Sun's shared memory transport (SHMEM)

If the Sun's transparent shared memory is enabled, IE hangs
on startup. This is established to be a Sun Solaris Bug,
reported as bug 4144519.

Internet Explorer User Interface Issues

o Experienced users of X11 can set color preferences using
  X resources with the class name "Iexplorer".

o When highlighting text in the browser window, Internet
  Explorer will automatically highlight whole words, unless
  the cursor is backed up over a word, in which case single
  character units can be highlighted.

o If you have more than one invocation of Internet Explorer
  running and one of the browser windows has a modal dialog
  open, the menu bars on all other Internet Explorer
  windows are disabled.

o When not running within a CDE session, Internet Explorer
  obtains its color specifications using standard X
  mechanisms with fallback values obtained from the file:
  <installation directory>/ie4/Iexplorer. This is an X
  resource file and contains instructions that will help
  the system administrator or individual user perform
  limited color and font customization.  Note: You may use
  the command line options to set the foreground and
  background colors - for example, "iexplorer -bg black -fg
  white" would be useful on a monochrome display.

Miscellaneous Issues

o If you delete the directory TempInternetFiles while the
  browser is running, the browser may hang.

o HTML pages that omit file extensions for image references
  are not rendered correctly.

o Renaming a "Favorites" folder with a name that has more
  than the leading letter capitalized will result in the
  name being unchangeable through the browser. Although it
  can still be changed as described in the "AN ALTERNATIVE

o Internet Explorer may leave files in a temporary
  directory (/var/tmp). These files are not needed and can
  be safely deleted whenever Internet Explorer is not

o If different people share a common user ID, network
  authentications made by one person may be available to
  others who are running simultaneous copies of the

o Form items and transparent GIF images do not print

o Address auto-complete does not always work as expected

  for addresses with mixed case.

o In the Mappings tab of the Internet Options Menu, the
  command line field cannot contain output redirection
  statements (e.g.: cat %1>/dev/audio).

o In the Programs tab of the Internet Options Menu, the
  news command or script specified cannot be passed more
  than one argument.

Outlook Express Issues

Extended Characters
Extended Character Set is not supported in the IMAP folder
names in this release.

Lock files for Mailboxes
If the write permission on /var/mail directory is removed,
the lock files for mailboxes won't be created.

First run of Outlook Express
The first run of Internet Explorer or Outlook Express on a
clean install may take up to 30 seconds to come up. Please
do not interrupt it by pressing CTRL-C, as you may corrupt
the registry file.

Unix Mail Spool
Attempting to read a Unix mail spool that was not written by
sendmail or /bin/mail may not work.

There are known compatibility problems when using fetchpop
in combination with Outlook Express' native SendMail
support. As a work-around, we suggest directly downloading
mail from the server by configuring Outlook Express to use

Deleting Mailboxes
Deleting Inbox.mbx or Outbox.mbx while Outlook Express is
running may cause Outlook Express to crash.

Mailboxes and Address Books from Windows 95 / Windows NT
Due to machine architecture differences, you can not import
these files into Outlook Express.

Monochrome displays
Colored text on a Monochrome terminal may not be displayed

After a period of time, an inactivity notification box may
pop up saying "server has unexpectedly terminated the
connection".  To reconnect to the server, simply select a
message or a newsgroup.

Text Based Mail Programs

If you regularly send mail to people who use text based mail
programs, you may want to change the mail setting under
Tools / Options / Send to Plain Text.  Some text based mail
programs may have trouble with mail containing a sequence of
multiple spaces.

If you have Outlook Express and Internet Explorer running in
separate workspaces under CDE, when you select
Help/Contents, you may need to change workspaces to view the
help text.
