if you are running the desktop version of codetwo exchange rules pro 1.4.2 or later you will notice that you can not insert an image to a signature … the dialog simple doesn’t appear …

to fix this:

  • first update to 1.4.4 (as i did not test this with version 1.4.2) …
  • then go to the server-installation of exchange rules pro (by default: “C:\Program Files\CodeTwo\CodeTwo Exchange Rules Pro\” on your exchange server)
  • and locate the file “C2HtmlEditor.UI.dll” …
  • copy that to your desktop-version directory (by default: “C:\Program Files\CodeTwo\CodeTwo ExchangeRules Pro Desktop\” on your client)
  • and restart the “Administration”-application …

this worked for me .. again .. using version 1.4.4 …
