owa url: https://inexyz.customdomain.com/owa/#path=/mail

iframe url: https://localhost:12345/messageread.html

the problem facing how can run addin project incustomdomain.com. if host on local iis while debugging how can append messageread.html page url iframe? there way change localhost:12345 customdomain.com while debuggin using visual studio.

to resolve above problem tried change project url in visual studio. i've checked checkbox "override application root url" , set custom url "https://machinename.customdomain.com/messageread.html" , instead of "iis express" set "local iis", created vistural directory same. if try brows messageread.html page using virtual directory it's working fine when try run solution (web addin project) it's showing "deployment error" , in error list window shows nothing.
