Windows 10: Outlook usage of SSD is 50% - fan blowing crazy

i am running Outlook desktop.

Since we migrated to O365, corporate policy limits our outlook to the online file + 1 archive.

Dozens of previously independant pst files have been merged into one of the two bases.

Since then I have performance issues.

My laptop is now blowing the fan as soon as Outlook is up. Close outlook, fan stops.

My M.2 SSD usage is constant 50% when Outlook is up.

What can I do to fix this ?

Problem: Explorer 50% cpu usage


Every day, at intermittent times unrelated to anything I do [it happens when I'm doing nothing], Explorer starts running with each core at about 50% cpu usage, and does not stop. Temperatures and fan speeds rise, fans become very noisy.

Speedfan indicates core temps rise to ~ 70 degrees C, "Temp1" rises to 75 - 80 degrees, fan 1 speed ~ 4000rpm,
fan 2 speed ~ 2500 rpm.

I have just installed Windows 10 so it seems it could not be caused by a virus/malware.

In windows 7 forums some users found the problem was caused by a corrupted file:

Explorer.exe 50% CPU usage - Windows 7 Help Forums

Since my problem is intermittent is it unlikely to be caused by a corrupted file?

I can't use the solution suggested in the W7 forums because when I kill explorer I lose my desktop.

I ran diskcheck on both my hard drives and it reported no errors found.

Any suggestions would be welcomed.

Can someone please explain why a corrupted file would cause explorer to run at 50% cpu usage?

Crazy fan

Hi our office ladies computer booted and did something weird yesterday, then today we tried to boot it, got to the windows startup page, then black screen and the fan revved up to the point where we thought it might blow.

Because it booted until the startup page, that means the hardware was not a problem but something with the windows package.

Please advise
