Hi Barry,
I agreed with Eddie’s solution, but you can also try other solutions to Boost up Outlook Performance. Few of them are listed here:
1. Disable unwanted Add-Ins from Microsoft Outlook
2. Turn Off Hardware Graphics Acceleration
After searching over the web, I found an informative article on Improve Outlook Performance. So, you can take more help from this article and boost up Outlook speed.
