PSA - Tip I found to help with Outlook slowness to load emails
I just wanted to share something I learned that helped me out a great deal with my Outlook desktop. I am running Outlook version 2512. I was having an issue where my Outlook was running frustratingly slow. Anything I tried to do in Outlook was sluggish, and especially opening, writing, and replying to emails was very painful. I would open an email and watch the ribbon load piece by piece across the top as it tried to load, and this could take 10 seconds or so for any email. Anything in Outlook was like this, as I tried to do anything and it was just load everything very slowly. For this PC, it's just a standard office PC with low specs to do the work. What I read, and observed through Task Manager, Outlook is using GPU to help with its processing. This basic office PC doesn't have a powerful GPU, so this was making it even slower. I found an article that suggested to disable hardware acceleration for Outlook. I did this and my Outlook has ran perfectly since, very quick and very snappy. This was a huge quality of life improvement. I created a registry key at: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Graphics DWORD(32-bit): DisableHardwareAcceleration 1 After this, a reboot is necessary. Just sharing this in case it helps someone else with the same issue.
