After opening notification emails, sent by CA PPM, in our Microsoft Outlook email client, there are sometimes large blue blocks towards the end of the email.
This typically seems to occur in the desktop client for Outlook, and doesn't seem to happen when viewing the same email message in Outlook for the browser.
Office 365 Installations with Microsoft Outlook.
The problem appears to reside with Outlook for Office 365. It isn't reproducible when viewing the same email message in the browser client for Outlook.
Install any remaining updates for your Office 365 installation, or work with your internal team to have updates installed for Microsoft Outlook.
A potential workaround for this until it is addressed in Microsoft Outlook is to view those affected emails within the browser client for Outlook.
