A recent large update hit our office Windows 10 machines, albeit staggered over a few weeks.
What we have found is that each machine that has been updated, the MS Outlook client is no longer capable of searching.
Now it may be a coincidence, but I'm not a big believer in co-incidences, particularly when Microsoft updates are involved!
Our email is supported by a third party who also provide us with an exchange server, but they seem to be at a loss and any suggested fixes such as rebuilding the index haven't worked.
Unfortunately our man Clive is quite reliant on the search facility so it's causes some pain. Anyone else had the same problem or come across any solutions? Microsoft suggest fix 101, re-install windows, so I'm hoping for a more intelligent response
