How does DragDrop for Outlook work and how secure is it?
Our add-in detects when a drag action starts and is dragged outside outlook, it then saves a temp file of the message or attachment to the local temp folder of the user (%temp% – this folder is only accessible for that user by default). We then wireup the windows drag event with a pointer to the file instead of the office item so a browser will accept the drop and recognize it as a file.
On interval (default 30 minutes, but configurable by your sysadmin) and Outlook start / close (depends on the interval and files) the temp files are cleaned up. We do NOT transfer ANY data out of the user computer. The only transfer you will ever see is a web call over https (SSL/TLS) to our licensing system to activate and validate the license.
Other questions we get about security:
- Who has access to data?
Only the user itself has access to the data.
- Is the temporary file encrypted?
If you want to encrypt the data, please do so on disk by enabling EFS or similar solutions.
- Where is data stored?
No storage outside the user’s machine is done, temporary files are saved in the user’s temp folder.
Can you notify me when there is a new release?
You can subscribe yourself to our release note newsletter.
This can be done by clicking at the following link:
When do I receive the download URL?
A download link will be emailed to you after your payment has been completed.
Why do I need a support license?
What does this license mean?
You need to have a support license in order to be entitled to updates.
Due to the evolves of outlook we need to make adjustments to our add-in to make sure it works every day.
When you have a support license, you will be able to use your add-in every day due to the updates we provide when a Outlook brings out an update (that causes interference).
What do you get besides updates?
- You get the possibility to get live support (with for example a teamviewer call)
- Phone, email and chat support (Business hours, CET.)
- Installation help
Can I move a license to a new PC or other user?
Yes, we have a migration tool available from the “my account” page.
DragDrop Setup Helper
We have provided a step by step manual to get your plugin working.
You can find the manual at the following link:
We have some adjustable registry settings available since the 5.0.1 enterprise install.
All information regarding the registry settings can be found at the following link:
I want specific control over the users that can use the add-in
You can do so in the registry. By default the add-in will be loaded for all users. However, this behavior can be changed easily by setting the loadbehavior id in the registry to 2 (manual, default value is 3 and implies automatic loading)
Now you can set the loadbehavior to automatic for the user based on their group memberships via GPO (or otherwise)
You can also instruct users that do not belong to the assigned groups to manually enable this via File -> Options -> Add-ins -> COM Add-ins.
How do I deactivate a license?
If you want to deactivate a license you should open the licenseinfo.exe, this can be found at C:\Program Files (x86)\DragDrop\DragDrop for Outlook (- Enterprise), depending on the install you ran. When you run the exe you should see the following screen:
Then there is the button ”deactive license”. Click on the button and it will be deactivated.
Can I do silent uninstalls (By command line)?
Ofcourse this is possible, use the following instructions:
The uninstaller program (unins???.exe) accepts optional command line parameters. These can be useful to system administrators, and to other programs calling the uninstaller program.
When specified, the uninstaller will not ask the user for startup confirmation or display a message stating that uninstall is complete. Shared files that are no longer in use are deleted automatically without prompting. Any critical error messages will still be shown on the screen. When ‘/VERYSILENT’ is specified, the uninstallation progress window is not displayed.
If a restart is necessary and the ‘/NORESTART’ command isn’t used (see below) and ‘/VERYSILENT’ is specified, the uninstaller will reboot without asking.
Instructs the uninstaller to suppress message boxes. Only has an effect when combined with ‘/SILENT’ and ‘/VERYSILENT’.
Causes Uninstall to create a log file in the user’s TEMP directory detailing file uninstallation and [UninstallRun] actions taken during the uninstallation process. This can be a helpful debugging aid.
The log file is created with a unique name based on the current date. (It will not overwrite or append to existing files.)
The information contained in the log file is technical in nature and therefore not intended to be understandable by end users. Nor is it designed to be machine-parsable; the format of the file is subject to change without notice.
Same as /LOG, except it allows you to specify a fixed path/filename to use for the log file. If a file with the specified name already exists it will be overwritten. If the file cannot be created, Uninstall will abort with an error message.
Instructs the uninstaller not to reboot even if it’s necessary.
Is there a MSI installer?
There is only a MSI installer when the enterprise edition has been purchased.
How can I test after installation?
Just drag any email or attachment to our test page:
No files will actually be uploaded or stored, so don’t worry about that.
Is there a separate installer for 32bit or 64bit?
The installer contains all files for both environments and autodetects the outlook version, so you don’t have to worry about that.
When I drag drop a message to Firefox it is moved to "Deleted Items"
- Make sure you update Firefox to the latest version
- Reset Firefox to default settings:
In the address bar type or paste: about:support
> Click the button: refresh Firefox
- Advanced option:
In the address bar type or paste: about:config
> Click the button promising to be careful
> In the search box above the list, type or paste autos and pause while the list is filtered
> Double-click the browser.tabs.remote.autostart.2 preference to switch the value from false to true
- A workaround for this issue is pressing ctrl while drag & dropping the message
Slow and Disable modus
In some circumstances Outlook decides to disable an add-in, because it detects a delay while starting or closing Outlook.
We do a cleanup of the temporary files on interval (and startup).
If there are a lot of files (or very big files) to cleanup it can take a few seconds to complete. Go to your Outlook and then click info, there you will see the option “Slow and Disabled COM Add-ins”. click it and then search for “DragDrop for Outlook” and then click “always enable this add-in” (Marked in red). After that restart Outlook and you are good to go.
