If one of your Legacy Email Composer emails was rendering with an unexpected red background in Outlook, even though it looked fine in Act-On's builder and preview, this is the fix: a new "Plain - no background" stationery that replaces the older Plain stationery causing the problem.
Quick Reference (Advanced Users)
- Default going forward: Content > Stationery, select Plain - no background, check Default.
- Per-email: in the email builder's Design tab, choose "Stock: Plain - no background" from the Stationery drop-down.
What's Changing
Act-On created a new "Plain - no background" stationery that can be used in place of the current one causing this issue. If you experience an email generating a red background, you can select the new Plain stationery for future emails which should resolve the issue by removing the body's transparent background color attribute.
From Content in the left side menu, select Stationery. In the drop-down menu at the top left, select Plain - no background. To use this new stationery for all new future emails, check the Default checkbox.

Additionally, you can select this stationery while creating an email or template. Within the email builder, in the Design tab, select "Stock: Plain - no background" from the Stationery drop-down:

Background
It was reported that some emails were displaying a red background to Outlook mail users, even though the email used showed a white background in Act-On's email builder and preview. The emails were using Act-On's built-in Plain stationery, which has an older attribute in the code that the Outlook mail client may not properly support.
