If the problem is with archive pst then run scanpst tool on the archive.

It's a free tool from Microsoft.

Not a pst issue as the 5 pst files could be read on another laptop:
also not likely all 5 pst are affected at the same time.

Rebooting Windows resolved it but would like to know what caused it

We cannot provide a root cause. If the PST was accessible from another laptop, then check the outlook profile on affected desktop. Try to configure a new outlook or windows profile.

Rebooting helps as certain Windows resource must have got exhausted

Commented:
This is because Outlook has a limit on the amount of memory it allocates to PSTs. You had too many PSTs open at once. Here is a good resource on this problem: https://answers.microsoft.com/en-us/msoffice/forum/all/outlook-has-exhausted-all-shared-resources-error/4fbd7390-e31e-40bf-97e6-b27f983cbec1
