Why Apps for Office options is disabled in my outlook 2013 instance

Question

I have developed a Mail app for outlook I want it to be available for outlook desktop but I can't see the "App for office" option enabled in on outlook desktop client.

I have checked with my outlook version it is up to date but don't know whats going wrong. Anyone can help in this, would be much appreciated.

Answer 1

After spending few hours I just give few trial by removing some COM add-in & profile re creation, perhaps some COM add-in causing the issue. So anyone can try with following to overcome such behavior of Outlook Desktop:

1. Remove any COM add-in which you have developed & debugging with outlook desktop client.
2. If problem persists than you can try delete profile & create again.

Go to control panel > Mail > Click on Show profile button, than delete exists profile & add again with followed wizard.
