Hardware: Dell Latitude 7490
OS: Windows 10
Office: 365 Pro Plus
Issue: The Outlook application sometimes goes white.
Setup: two external LCDs in addition to the laptop's LCD.
Troubleshooting steps: Ran Windows Update and Office is updated.
2. Hardware acceleration is already disabled in Outlook
3. All the device drivers are already updated, via Dell Command Update
Additional hardware; Dell WD15 docking station with the latest firmware.
2. One LCD is a 22 inch and other I believe is about 17 inch.

Observation: Since the problem only affects the Outlook application, it is related to video memory.
