Outlook O365 Slow

[Tyler Miller]

I have a user who has complained that scrolling his inbox in Outlook Office365 after the recent update (to refresh the look) is very slow. I saw what he was referring to and it is laggy. It did not occur before the O365 update. Anyone else seeing this same issue? Any known fixes? I should note that nothing has changed, but that he does have his font increased so he can see the text better. Maybe in the new interface this causes lag?

Hi Tyler,

Have you tested if the issue happens why Outlook is opened in safe mode? Outlook.exe /safe

Which update might that be, you are not being very specific here. One of the recent changes that were introduced in Outlook is a redesigned display stack to better handle multi-monitor setups and differences in DPI. This might cause issues in some cases, so you can try toggling the setting off: https://support.office.com/en-us/article/office-support-for-high-definition-displays-6720ca0e-be59-4...

You can also try toggling hardware graphics acceleration: https://support.microsoft.com/en-us/help/2768648/display-issues-in-office-client-applications

Thank you, we will try these and report back.

Weird, I am able to see what the link is referring to, but the employee with the issue does not see some of the settings in his General tab. I had him check and he is running the latest version of Outlook. How can one Office 365 tenant have employees on different version of Office?
