Outlook 2016 Lagging Windows 7 SP1 Fully
Outlook 2016 Lagging Windows 10 Pro 1809

I have disabled hardware graphics acceleration, disabled animations in outlook, made sure they had a fast network connection, did profile repairs, they are also using cached mode.

Are they running reasonably capable systems If so, is your antimalware doing a scan when this happens.

Ive seen exactly this when using a 40w psu in a machine that needs 65w psu.

Other than that, try having the resource monitor open to catch whats happening when the issue occurs.

If its a ramcpu limitation, they should be at or near 100 usage when it happens.

Our reboot process takes about 6 minutes due to multi-factor authentication and anti-malware group policies that load to keep our machines safe.

It would be one thing if we had downtime, but in our industry, every minute truly matters.

I am just trying to find an advanced solution that will fix it.

I even spent hours calling and chat messaging Microsoft in attempts to find a resolution.

The strange thing is when I boot outlook in safe mode it runs just fine.

Disabled add-ins were; Skype meeting add-in, outlook social connector, one-note notes, Microsoft VBA, and Microsoft Access data collection.

If you reboot are they OK for a while then it turns to molasses or permanently slow Windows 7 SP1 fully patched.

In my cases only the one reboot solved the problem and it never returned.

Part of me wonders if at a point our firewall blocks the ping initially to MS servers until it can pick up the new location.

The machine in question is a Dell Latitude E7450 w an i7 Process, 8GB RAM and an SSD, running Windows 10 Pro 1809 - so a pretty zippy machine.

Typing in Outlook when composing new messages or calendar entries was laggy.

Go to System Properties - Advanced - Performance - Settings - Visual Effects - uncheck the top box called Animate controls and elements inside windows.

Thats it. No reboot required.

When I opened Outlook 2016 again, the lagginess was gone.
