Integrating Dropbox with Microsoft Outlook

Dropbox is the de-facto standard for file synchronization. It is present on both desktop and mobile operating systems. Why not integrate Dropbox within applications themselves? We have developed an Outlook add-on to attach files residing on Dropbox. The sender chooses files synchronized by Dropbox from a new Outlook panel. and the recipient can open the attachment via a published URL. If the file is public then it can be downloaded from a public URL. Private files are published on a secret url and shortened. All the details are handled behind the scenes using the Dropbox API. Dropbox automatically assigns the expiration date for the files. This information is summarized in the e-mail.

Dropbox is an excellent addition to managed file transfer solutions, as it eliminates the need to spend money and time on developing and deploying applications for different platforms. Dropbox already synchronizes files across Microsoft Windows, Apple OS X, Apple iOS, Linux, Android, and Blackberry. Windows Phone 7 does not have an official Dropbox application yet but unofficial ones have already been created with the Dropbox API.

Microsoft Outlook is the most popular desktop e-mail client in the world (link to campaign monitor statistics). Integrating Outlook with Dropbox via a plugin is a no-brainer offering. The plugin could be expanded in the future to incorporate automatic synchronization of files attached outside Dropbox to the Dropbox folder.

Another important benefit of using Dropbox within Outlook is that it allows you to easily attach very large files like movies or virtual machine images for applications such as VMWare, VirtualBox or Hyper-V.

    Any update?

    • Sebastian Wain

      It is working.

  • Artists Circle

    This app is great, but I would love for it to be able to browse to any local/network folder, choose a file then automatically copy that file to your Dropbox public folder and attach. This would make for a brilliant replacement for YouSendIt and their Outlook plugin.

  • WiSch

    Hi. Works like it should, thanks for that. But it’s not possible to upload a new attachmet into my dropbox via this AddIn? Is there really only the way to upload via Dropbox itself and than attach it to my mail?

  • David Chaves

    Awesome plugin!! The only “bug” or “feature” its when I close the Dropbox explorer I haven’t find a way out to open it again, hope that you can workaround this in any future release. Great plugin folks!

  • Adam

    My antivirus just removed the plugin citing spyware – so BEWARE!

    • Sebastian Wain

      Can you post the exact message and the antivirus that you are using?

      • Sebastian Wain

        We are looking forward to your response. If you don’t answer in a few days with more information your comment will be politely removed.

    Is there any way to remove the footer “My Dropbox Attachments” when I’m not sending attachments? Only a small fraction of my emails use this, but every single email is tagged, even if I close the browser.

    • Dimitris

      Yeap, I am having the same problem too…

      • Cucky

        Has someone discovered how to remove the footer “My Dropbox Attachments” ????

  • James M

    how do you install the plugin?

  • gregorywellsclifton

    Help a really challenged person here please, technologically speaking. I installed this Nektra……………… so that emails go to Dropbox. I can’t find where it is installed on my laptop, and then, how would I get my mails to Dropbox? My PC is about to be ‘crashed’ and my ISP has not got my many mails from before yesterday on their system as I hadn’t clicked something or other. Don’t want to (cannot afford to), lost all this info. Thank you

  • Jon Looney

    any way to open up more than just the Public Folder?

  • Marc5000

    Some users (on our domain) can’t see the plugin in their Outlook (2007). I installed it for everyone using the admin account, however no user sees the add-in on outlook. When I try add it manually it claims it’s not a valid plugin? Thoughts?

  • Buddy Shipley

    Question: In the slideshow pics I see Dropbox folders: Other, Photos, Public. Are these accessible from within Outlook via the Dropbox Explorer? Can users create additional public or private folders here, and drag & drop email messages into them (rather than store them in sync’d IMAP folders)?

  • TheBuddyLama

    Does this work with Office365 / Outlook 2013 ?
    When the Nektra Addin for Outlook tries to connect to drop box, it prompts for a login to Dropbox:

    “Sign in before linking with Nektra.Outlook.ManagedFileTransferAddIn”

    Then it reports an error: “There was a problem completing this request.”

    • TheBuddyLama

      Solved: I had to close& re-open Outlook again.

  • Cliff

    hi, using dropbox plugin in Outlook 2013, got “An error occurred while trying to access your Dropbox account” in dropbox browser in Outlook and no folders are shown in dropbox browser.

    Any advice on resolution?

    • Swickers

      I have the same problem with Outlook 2007, any help would be appreciated.

      • Matias Palomera

        Can you give us more information about the pc environment? Version of Office, Operating System, etc.

    There is one really helpful feature you could add to this, more on the receive side than the send side. I would really like to be able to designate a folder in my dropbox to receive incoming attachments. Then, all incoming mail would be stripped of attachments and all of those attachments saved in my designated dropbox folder. This would help a lot to combat the overflowing-mailbox-quote so many of us suffer from, especially when the primary culprit is huge incoming attachments :) [The addin already solves the huge *outgoing* attachment problem, this is just the other half :) ]

  • Rakewell


    This would be an amazing tool – if it worked!

    I’m running Outlook 2010, and am getting the same “An error occurred while trying to access your Dropbox account”….
