Expected behavior

Outlook installs my addin manifest file.

Current behavior

Outlook cannot install my manifest file.

Steps to Reproduce

1. Unpack attached archive.
2. In the folder with archive content, find the manifest file
3. Validate the manifest file with office-addin-manifest script:
   3.1 in Terminal.app execute the command:
   office-addin-manifest validate MyOutlookAddin.xml
   Note that the script reports manifest file as valid:
   The manifest is valid
4. Try to add custom addin from attached manifest to Outlook.
5. Installation failed

Context

I tried to install addin in Outlook for Mac, and in Outlook on the Web.

MyOutlookAddinManifest.zip

Start by unpacking MyOutlookAddinManifest.zip and running office-addin-manifest validate MyOutlookAddin.xml as described. Compare the validator's result with installation in Outlook for Mac and Outlook on the Web; done means the validator identifies the manifest problem or the manifest installs successfully.
