Outlook Lag issues

Question

A couple weeks ago my Outlook that I have through my work started lagging. Mostly jumpy scrolling, slow switching between windows, typing delays. Oh and if I scroll really quickly down a chain (have an mx master mouse so I can throw the scroll wheel) it will start beeping. If i scroll up and down the thread a few times it will eventually start scrolling fluidly. 

I've since deleted my profile, the ost, pst, and uninstalled and reinstalled office using microsoft's tool. Last night after my emails finally re-downloaded and indexed, the issue was gone but by the morning it had returned.

It's a exchange email. I get a large number of emails but I have the same setup on a laptop and a computer in the office with no issue so I don't think it's a matter of inbox size etc. 

Issue persists in safe mode. Feels like it's in other office products but I mostly use outlook so I'm not sure. Feels like I've tried everything on every forum I can find. It's not the mouse - been using this one for years and since the issue was fixed briefly after the reinstall. Actually in case this is helpful I also tried just doing an office reinstall without deleting the profile and the problem was fixed briefly. 

Computer is running Office 365, Windows 10 Home, i9 9900kf at 5ghz, 16 GB Ram, RTX 2070super.

I'm on Outlook for 12+ hrs a day so this is really trying my patience. Any advice greatly appreciated!

Answer 1

Posting in hopes that someone who runs into this issue will find this instead of wasting all the time I did. The issue is caused by having two different monitors. It's a common issue with windows apparently and is discussed frequently in regards to video game issues.

The version that is brought up most commonly is having a 144hz or higher 1440p monitor and secondary 60hz 1080p monitor. 

I haven't solved the issue. Apparently it can be caused by one or all of the following: different resolutions, different refresh rates, different cables (displayport for one monitor and hdmi for the other). It doesn't seem like there's a good solution besides buying two equivalent monitors.

Answer 2

Okay you are right about it being a display issue. My primary monitor is a 144hz 1440p Acer Predator while my secondary monitor is a 60hz 1080p monitor. When I disconnected the 1080p monitor, the lag went away (same thing when I disconnected the 1440p one).

I've now reconnected the 1080p monitor, so using both of them again, and the lag seems to be gone. I don't think unplugging and replugging in is a permanent solution but this gives me a whole new angle to research. 

If anyone has a recommendation for this i would really appreciate it.

Answer 3

How would you diagnose/fix that?

Not sure if this is helpful diagnostiaclly, but when I completed the uninstall yesterday and the computer rebooted I got a couple error messages that I was missing a couple C++ things. I redownloaded one of the packs and it went way.

Answer 4

Its unlikely to be an Office issue, but more likely a win/display/video issue
