contentACCESS MailApp installation issue

Introduction​

This page describes a known issue that can occur during the installation of the contentACCESS MailApp, where the Exchange server is unable to download the MailApp manifest file. It explains the cause of the error and the steps required to resolve it.

warning

Important: The MailApp manifest XML file is sent directly to the Exchange server during the installation of the MailApp. If uploading the manifest fails for any reason, the manifest URL is sent to the Exchange server as a fallback. In this case, the Exchange server must have access to the manifest file on the contentACCESS server. If access is not granted, the error described below can occur.

Problem​

The following error message appears during the contentACCESS MailApp installation (Provisioning job run):

"The app couldn't be downloaded."

Solution​

This problem occurs when the Exchange server cannot download the contentACCESS MailApp's .xml manifest file from the contentACCESS server.

To successfully install the contentACCESS MailApp, the Exchange server must have access to the contentACCESS server and to the contentACCESS MailApp's .xml manifest file. The manifest file can be accessed using the following links:

  • https://[SERVERNAME]/contentACCESSWS/Mailapp/Mailapp.xml
  • https://[SERVERNAME]/contentACCESSWS/Mailapp/Mailapp_no_ribbon_button.xml

The administrator should be able to browse the file using the links above without any issues.
