I added notification of what the checkmark means, automatically load the Exchange snapin if not already, and append the subject of the email with a status summary. If there are no backups that need attention, all okay is added. If there are, it says that attention is needed. This provides a quick way to know if anything needs attention. Download the script here.
Version 1.11 correctly resets the checkmark status during each loop; when cleared before because no backup has taken place, it remained as a null value for later backups that were successful. Updated version is available here.
I have made some minor updates to my PowerShell script that reports (and emails) the last backup of each database in your organization. I was referencing the wrong variable when looping through the databases in a storage group, so each storage group in the report listed all the databases on the server. I also change the formatting a little so the text in different table cells in the same row actually look to be in the same row (the checkmark was offsetting that cell a bit). You can download v1.1 here.
