Using older versions of Outlook for Mac in business environments
No it was not. The issue is still there. Add an image to your signature and you get a popup "Some of the files in this Web page aren't in the expected location ..." (two popups). Press "Yes" on both popups and you get your signature with image and all. Press "No" and you get a red cross where the image should have been (missing image). I'm on build 160916 v. 15.26.1
