Saving Email Messages and Attachments to Egnyte

  1. Open an email in Outlook. If the Egnyte for Outlook icon is pinned, it will appear to the right of the message header. Otherwise, access it from the (…) menu, as shown below

  2. Click Egnyte - a separate pane opens, displaying the email with the subject name as an .eml file and listing the attachments with checkboxes. By default, selecting Select All chooses all attachments. To exclude certain attachments from being saved to Egnyte, clear the checkboxes next to the unwanted files

  4. A progress bar will appear next to each file during the saving process. Once all files are saved, a summary screen will be displayed. If any attachments fail to upload, a retry option will be available next to the file with the corresponding status

  5. Once all attachments are saved, the user can preview the attachments by clicking the View in Egnyte link, which opens a new browser tab. To open the email message in Outlook or any installed mail client, use the Egnyte Desktop App and double-click the saved email file. This will open the email with attachments, allowing further actions

Sending Shared Links to the Egnyte Files or Folders via Email

  2. In the third-party application bar at the top of the new message window, click Egnyte in a Pinned bar or click on the office ribbon. Select Share files

  3. An Egnyte dialog box opens, displaying the Egnyte folders in a long list. Scroll down until the required folder is visible, then click to open it and select the desired file. For ease of access, the last ten recent files and bookmarked folders are also displayed. User can also search for file names.
  4. Select a file or folder to share (only one file and one folder at a time can be shared)



    By default, the shared link permissions are set to the default settings in the Web UI.  Users can adjust the permissions on the shared link. To do this, click Select to choose a file or folder, and choose the available options on the Sharing Parameters screen

    • Anyone
    • Anyone with password 
    • Egnyte File Server Users
    • Domain users with permission
    • Specific Recipients
  5. The message redisplays, and Egnyte links are displayed within the email body

  6. Click Send when done. The recipient receives this email with Egnyte's shared link(s). The recipient will need permission to view files shared in the Egnyte Collaborate platform. 

The link is displayed as an icon that can be moved within the body of the email message, for instance, to place between paragraphs or just above the signature. The location of the Egnyte (Add-In) icon varies depending on the Microsoft platform in use, such as Web Outlook Client, Desktop on Windows, or Mac. If the user uses the new Outlook Web app, the Egnyte icon is displayed within a drop-down menu in the lower toolbar (when creating a new message) or in the top-right toolbar (when opening a message) if pinned, or via a bar with an overflow menu (...).

  4. In the next step, define sharing parameters
    • By default, the link permissions are set to Anyone 
    • If links need to be active for a certain amount of time, set an expiration time, which will prevent uploads after the designated time frame. The drop-down menu offers various time options such as 1 week, 2 weeks, 1 month, etc.
    • The Create separate folder for files received from each person option will store each recipient's files in a unique subfolder.  For example, if 100 people uploaded files via an upload link, then 100 subfolders will be created with each recipient's name, email address, and their respective files.
