The add-in displays a blank screen after entering your company ID

If your add-in is showing a blank screen after entering your company ID, it means that you entered the wrong company ID, and you'll have to refresh your cache to be able to re-enter the correct ID.

To resolve this blank screen issue, you must manually clear the add-in or the Outlook cache. Note that clearing your internet browser cache doesn’t clear the cache for the Inpart Add-in for Outlook, you'll need to proceed following the instructions below.

Option #1 - Refresh the add-In

For that, you can either:

  • Click right with your mouse in the add-in pane (i.e. in the blank area) and select Refresh.

The Inpart add-in is unavailable (grayed out or not visible)

The add-in can't be used, and hence the icon is grayed out or invisible, on the following occasions:

  • You haven't selected an email.
  • The email selected is a draft email.
  • You try to push a .msg or .eml file attached to another email.
  • You try to push a .msg or .eml file opened from your computer file system.
  • You try to push an email from a shared mailbox, an archives mailbox, or a public folder.
  • Outlook is in offline mode.
  • You're in the list view of the mailbox. You must display the reading pane. 
    For instructions on how to turn on the reading pane in Outlook, please read this Microsoft article: Use and configure the Reading Pane to preview messages.
    If you don't want to enable the reading pane, the add-in will only be available from the Message tab on the ribbon when an individual email is open.
