Product release information for SafeSend version 5.4, released on 2024 March 26.

What's New

We are pleased to introduce SafeSend version 5.4 – an iterative release strategically crafted to bridge the gap between our previous 5.3 release and the forthcoming 6.0 product revamp. With 5.4, we're delivering a comprehensive amalgamation of fixes, feature enhancements, general improvements, and reconciliations of PC/Web add-in functionalities. Notably, this version responds directly to the requests of our valued customers, who seek to further expand the SafeSend footprint within their businesses.

Web Add-in

New Settings

  • PopupForBccWarning: Displays the SafeSend confirmation dialog when the following conditions are met: other popup settings are false, the BCCWarningIfMoreThanX_TOCC_Recipients setting is configured, and the recipients are greater than the value configured here; enabled by default; can be found under Advanced
  • PopupForMaxNrRecipients: If there are multiple external domains, but the MaxNrRecipients is exceeded with all PopupFor* settings disabled, the PopupForMaxNrRecipients will trigger a confirmation prompt when set to TRUE; enabled by default; can be found under Advanced
  • TreatExternalExchangeDLAsUnsafe: Considers a recipient unsafe if Microsoft Exchange reports the recipient is a distribution list with external recipients; can be found under Advanced
  • HideDLPResultsFromLogging: Hides DLP results from logs since they may contain sensitive data; enabled by default
  • HttpCacheMaxAge: Specifies (in seconds) the duration that some http responses will be cached in the Outlook client; increasing this time can reduce server load, but can also increase the time it takes for setting changes and updates to apply; set to 0 by default
    • Note: Having the HttpCacheMaxAge set to 0 is the behavior of previous SafeSend versions
  • AppTenantID: A new required setting in the Microsoft Graph API set up as part of a SafeSend health check; you can check the health of your app in Azure under Overview at the top of the screen; health is determined based on whether the following settings are configured appropriately:
    • AppID
    • AppCertificateThumbprint
    • AppSecret
    • AppTenantID

Other New Features

  • Recipient Removal allows you to remove external recipients directly from the SafeSend confirmation window for messages and events
    • If using Outlook 365, Groups that are listed as external recipients can be removed/re-added from the SafeSend confirmation window; Contact Groups are not included and cannot be removed from the SafeSend confirmation window
    • If using Microsoft Exchange, Distribution Lists/Groups that are listed as external recipients can be removed/re-added from the SafeSend confirmation window; Contact Lists that are listed as external recipients are not included and cannot be removed from the SafeSend confirmation window
    • DLNamesasExternal and DLNamesAsUnsafe must both be configured
  • Attachment Removal allows for attachments listed in the SafeSend popup dialog to be removed when sending a message

Important

Due to a limitation outside of our control, the Attachment Removal feature does not work in the following environments:

  • Microsoft Exchange in any browser
  • Outlook for Mac (Microsoft365 account)
 
  • SafeSend now creates logs of the user of the email client instead of the local server user
  • The size of attachments is now displayed next to the attachment name in the confirmation dialog box when SafeSend knows the attachment size
