Saving Email Messages and Attachments to Egnyte

Note: All saved emails and attachments now have unified naming conventions to make it easier to find the saved content. 

When saving emails (.eml) to Egnyte, they are named in the following format: 

Timestamp YYYY-MM-DD_hourminutessecond [time when email was received in UTC]/ sanitize(title)[140characters}internalMessageid [10characters].eml. 

For example: 2026-01-28_141245 Acme Proposal be0e50390d.eml

Similarly, when saving attachments to Egnyte, they are named using the format below: 

Timestamp YYYY-MM-DD_hourminutessecond [time when email was received in UTC]/ sanitize(title)[140characters}[sanitize(Attachement name)[60characters]]internalMessageid + attachmentId)[10characters].file type.

For example: 2026-01-28_141245 Acme Proposal prop_RFP_Design_Town_Hall_and_Facilities_Remodel a63353a0d8.docx

1. Open an email or select multiple e-mails 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
   
   Multiple e-mails selected
      
   
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
   
   
3. In the next step the user needs to click on Select location and select a folder location for saving content to Egnyte.
   
   • User can use All Tab to select folder from the file structure
     
     

     It is not permitted to save an email directly to the /Shared or /Private folders. Users will need to select the subfolders.

     
     
   • User can use Bookmarks tab to select a folder from the bookmarked folders (these are the same bookmarked folders available in the Web UI)
     
   • Users can also use search to find the folder
     

4. Click on Save to Egnyte button after making the selection.
   
   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. This opens the file in Web UI in a new browser tab.
   
   

How to Open uploaded e-mails and attachments

To open the uploaded email message in Outlook or any installed mail client, use the Egnyte Desktop App and double-click the saved email file. This will redirect the email with attachments to the appropriate e-mail client application, allowing further actions.  

Auto-added e-mail metadata tags

Depending on selected settings, metadata tags will be added to all saved emails and attachments to make it easier to find saved content. Auto-added email tags are visible in the file Details > Metadata > Custom Tags under the namespace Outlook 365 

File metadata tags in the WebUI for uploaded e-mails

File metadata tags in the WebUI for uploaded attachments

Users can enable or disable the setting to auto-add metadata. It is available under Settings in the Outlook add-in hamburger menu.
 

Enable or disable the toggle as needed.

Additionally, the following settings are available:

• View Metadata Namespace: Users can click on the option and they will be redirected to the Egnyte Domain settings and can look for Outlook 365 namespace in the listing.

• Remove Metadata Namespace: Selecting this option will delete the metadata namespace. Please note that this action is retroactive and will also remove metadata from files already saved to Egnyte via the Outlook add-in.

   • 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.
     
5. Click Share link when done and the Egnyte upload link is displayed within the Email body. Once the email is sent, the recipient receives this email with Egnyte's upload link.
