Outlook Plugin

The Outlook Plugin is supported on Microsoft Outlook version 2000, 2003, 2007 and 2010 (Outlook 2010 64bit is supported in version 1.6 and latest versions of 1.2.x beta plugin).

The plugin is considered beta and there's currently no built-in help available.

All versions of the plugin require .NET Framework v2 and the VC++ runtime library to work. The .exe's have the runtime library builtin, or set to download it automatically if required. If you want to use the .msi and the library isn't already installed, it can be downloaded from here: vcredist_x86.exe.

This version of plugin will ONLY work with server 1.6 Users of server version 1.5.x, please download latest version of plugin 1.2.x below.

Known issues in the stable beta

Most importantly, lack of OL2010 support. See changes log below. For OL2010, use the current beta.

Known issues in the current beta

On some systems, large files (300MB+) are not always uploaded successfully as HTTP error is produced, when connection goes through proxy servers. You are able to tweak upload behavior using registry configuration settings, see below.

You can copy the following code to .reg file to create stubs for registry settings

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\AllardSoft\SFT]

“AutoUploadInKb”=dword:00002800

“BufferSizeKb”=dword:00000100

“NoCheckValidEmail”=dword:00000000

“Server”=””

“TraceFile”=””

“WriteWebResponse”=””

“UploadUseHttpVersion10”=dword:00000009

“UploadRequestPipelined”=dword:00000009

“UploadRequestKeepAlive”=dword:00000009

“UploadRequestChunked”=dword:00000009

The default setting is to add any attachment above 10Mb as a SecureAttach attachment. To change this, please edit:

HKEY_CURRENT_USER\Software\AllardSoft\SFT, AutoUploadInKb

As of version 1.6.11, it is possible to use task pane region instead of custom region. This technique is intended to use when certain addins or other software come with conflict wiht the custom region.

• All settings are checked under HKEY_LOCAL_MACHINE first, then under HKEY_CURRENT_USER if the value is missing

• In both cases, path is Software\AllardSoft\SFT

By default, version 1.2.69 emulates IE upload headers:

To reconfigure application to use the same mode as in previous versions,

This is the current beta

• Resolved: Registry settings incorrectly read or defined on x64 systems.
• Starting from this version, HKCU settings take prevalence over HKLM settings
• Resolved: In certain scenarios, attachments with size over 9KB were always uploaded securely
• Resolved: In certain scenarios plugin crashed when trying to ask for credentials

• Resolved: Outlook 2007 or 2010 crashes in some scenarios of secure upload process
• Resolved: Panel specific for Outlook2003 shown with Outlook 2007
• Supports “Require Users to Authenticate” settings defined at the server

• Resolved problems with 32-bit Outlook running on Windows x64 bit (drag-and-drop crashing Outlook, url to download attachment not injected into Outlook message)
• Trace logs and dumps of XML responses are written to default log location under My Documents\Add-in Express folder
• Enhanced visualization of control panels: control panel designed for Outlook 2000-2003 never shows with Ribbon interface (as it's duplicate), plugin is invisible and not “minimized” by default in Ribbon interfaces until SecureAttach command is used.

• support for OL2010
• support for integrated Windows authentication on proxies
• support for Exchange2003 (some Exchange objects don't provide meaningful address information, so querying that information from object's original display name as the last resort)
• awareness of KB2445403 problem
• tracing log
• all available registry keys can be defined on HKLM as well and included into setup package
• enhanced upload speed
• SecureSend function

• Initial support for Outlook 2010 x64
• Integrated authentication supported
• When an attachment over 10Mb (configurable) is added it is SecureAttached automatically
• Drag-and-drop supported properly
• Cosmetic changes, like when user adds an attachment, pane is expanded automatically
• Issue resolved: there was improper cancellation routine when user closed mail window without canceling upload first

• Option not to upload message body at all.
• Setup package for per-machine installation is now available
• FIX: on some ocassions, extra two bytes were appended to file.
• Outlook 2010 is now supported (except Outlook 2010 x64; note that 32-bit version of Outlook 2010 is fully supported on 64-bit Windows)
• Partial, beta support of Outlook 2010 x64
• Outlook 2000-2003: Secure File Transfer panel is minimized by default. With built-in editor, it is possible to hide it completely (use Configure form); use Insert → Secure File to insert a new file and show the Secure File Transfer panel.

• New messages are no longer saved to “draft” when user hits escape without entering anything
• OL2007: Ribbon used to disappear sometimes; this is no more.
• When using Exchange: default SMTP address can now be used instead of first SMTP address.
• This is governed by checking exchange/use_pr_smtp_address node in the login sequence
• There's option to add message in front of body (instead of appending it).
• When user right clicks and chooses “Send to” from shortcut menu to display dialog window, OL2007 no longer crashes.

• The plugin now remembers the last setting of the secure download setting.
• The plugin now correctly sets the timeout from the defaults in the appliance.
• Credentials are no longer asked for during installation. Instead they will be asked for during first send. If you want to revert to the old behaviour to ask for credentials during setup, please set HKEY_CURRENT_USER\Software\AllardSoft\SFT, make dword entry named “SilentSetup” with value 0.

• Automatic detection of http/https when connecting to the Secure Filetransfer appliance.
• Interface update to make it clearer when a file has been uploaded.
• Better reporting of connection/authentication errors.
• Various Bugfixes

• First public release

• Please make sure that you have entered the correct server name.
• The Outlook plugin uses the proxy setting from Internet Explorer. If you have a proxy on the network, please make sure that it will allow xml posts through, and that the proxy can access the Filetransfer Appliance. An alternative can be to change proy settings to connect directly to the Filetransfer Appliance.
• Please make sure that any application aware Firewall, Intrusion Prevention System or Proxy is not blocking connections between the Outlook plugin and the Secure Filetransfer appliance. Please see the API Documentation for a complete list of connections that will be performed between the Outlook Plugin and the Secure Filetransfer appliance if you want to tweak any such potential traffic blocking system.

* Please note that with Outlook 2003 or lower there's no ribbon, and the plugin's user interface may be invisible by default. In that case, use Insert→Secure Attach command to make plugin's user interface visible.
