Installation Guide for Emailgistics Add-In for Microsoft Outlook

As of June 2021 Emailgistics has two versions of our Outlook add-in available (depending on your version of Outlook). Version 1 and 2 of the add-in provide identical features, however, Version 2 takes advantage of a recent Outlook update to provide better performance.

Version 1 of the add-in, which is compatible with the older version of Outlook listed below, requires Emailgistics to add the user identifier info into the message header “on send”. This means immediately after you hit the send button there may be a 1-3 second processing delay to add this user identifer info.

If you are on the Current Channel of Office 365 and have Outlook build 14026.20246 or greater you can use Version 2 of the add-in. Version 2 tells us when you hit reply or create a new message and allows our add-in to act right then. This means we can add the user identifier into the message header while you are busy crafting your message, instead of when you are trying to send it.
