Release Notes for SafeSend BETA - Sept 17, 2020

Written By Marissa Fegan (Super Administrator)

Product release information for SafeSend v4.6 BETA on September 17, 2020.

What's New

SafeSend v4.6 now includes a web add-in solution under the same license you've been using for your Windows Installer-based deployments. The new web add-in has basic send confirmation and supports OWA (Outlook Web Access), Outlook for Windows with Microsoft 365 or Exchange Server, and Outlook for Mac with Microsoft 365. The web add-in .zip file provided to you is a ready-made website that you can host in IIS (Internet Information Services) on any .NET 3.1 Core capable server, including Linux! See Microsoft's .NET Core Documentation for full details.

Please note: Data Loss Prevention is not currently available with the Web Add-in but is scheduled for a future release.

We've also simplified domain-based licensing. Those who frequently change 'Safe' domains no longer need to update their license to accommodate! One important thing to consider is that the license is now tied to the sending domain so you may still need to license multiple domains if you have multiple domains that you send email from.

Special Instructions

If you are using the SafeSend web add-in with IIS Server, the latest version of SafeSend v4.6 requires .NET Core 3.1 Hosting Bundle to be downloaded and installed. See full details on our beta test welcome page

If your intent is to use both the COM add-in for Outlook for Windows and the Web add-in, set the PC platform to False from within Settings.json to avoid double prompts.

VIPRE Recommends

Any changes made to Settings.json require the website to be restarted to take effect. We recommend doing this outside of normal operating hours to avoid potential service interruptions.

Known Bugs

Ticket Number Description Workaround
SAFE-302 When using OWA in Safari and Exchange Server, SafeSend dialog doesn't display

This is the result of a known Microsoft bug. For details, visit: https://github.com/OfficeDev/office-js/issues/1057
You can use other browsers that work in macOS such as Firefox, Chrome, Opera, etc. With this option, it's recommended to block access to Safari to avoid the known issue. 
SAFE-314 When using Mac Outlook and Exchange Server, SafeSend dialog doesn't display

This is the result of a known Microsoft bug. For details, visit: https://github.com/OfficeDev/office-js/issues/1057
There is no known workaround at this time.
SAFE-315  Notifications from SafeSend are not consistent across platforms.

For example: In Microsoft 365, it will show up as informational but Exchange will show the same notification as an error with different verbiage.  

Please see the attached screenshot.

Error messages may include the following:
  • Outlook can't send this message because there's a problem with the add-in SafeSend - Confirm External Recipients
  • The add-in SafeSend- Confirm External Recipients is blocking this email from being sent.
There is no known workaround at this time. This is a Microsoft bug.
