Add-In being immediately removed after install from URL RRS feed

  • Question

  • My team has been developing an add-in that I have been installing via URL to test. Up until the last couple of days there have been no problems and we haven't changed anything, however now after I install (I then see it in my list of add-ins and I see the launch button), but after a few seconds it all disappears. What would cause something like this?

  • Hi Steven DeConto,

    Is the add-in an office add-in or an VSTO add-in? How do you install it? Does the add-in customize UI and is there any error message? Besides, will the issue still exists when you install the add-in form local path?

    What's the version and building number of your Outlook? Outlook updates recently, if you have updated your Outlook, I suggest you revert to a previous version to test if the problem still exists.

    Best Regards,
