Microsoft Outlook Plugin Reply All With Attachments

A great Outlook feature is that it can be extended with plugins. Similarly to how the Mozilla Thunderbird email client or the Firefox web browser can be extended, but with the exception that there is no central plugin repository and no comfortable way of managing the plugins.

Reply All With Attachments is a specialized plugin for Microsoft Outlook that has been designed for users who regularly include attachments that were attached to email messages that they received.

It enables you to include attachments automatically that you have received in an email when you reply to all recipients of the email message (which can be only one of course, or more). The add-on has been tested with Outlook 2007 but chance is that it will also function with previous and future versions of the email client.

It has a few additional requirements especially the VSTO 4.0 runtime. The Reply All With Attachments plugin can then be installed by double-clicking the downloaded file. Users should ensure that Outlook is not running during the installation as it won't work properly otherwise. A new entry called reply all with attachments should appear under the custom actions button in the main Microsoft Outlook menu.

A click on the new entry will automatically open a new email with all attachments of the original email attached. All recipients that have been listed in the original email will also be added as recipients in the new email. Reply All With Attachments is available at the developer's homepage.

Note: Microsoft enabled an archive mode on Codeplex that changes how you download the plugin. You need to click on download archive to download the entire archive. Once done, extract it on the local system and open the releases > 0 folder. There you need to add the .zip extension to the largest file in the folder and extract it. That gets you the plugin installer so that you may install it on your system.

To uninstall the plugin for Outlook close the program and use the Control Panel uninstall a software applet to remove it. It is listed as ReplyAllwAttach there.

Update: The plugin is compatible with Outlook 2019 and requires the Microsoft .Net Framework 4.0 on the system as it won't run otherwise.
