Strange Searching issue in Outlook.
One of our clients regularly emails a customer with the surname "Button".
When searching for the word "Button" in Outlook it returns many irrelevant results. We had the same problem with the word "French" but we found that the word existed in the email attachments of, what looked like, irrelevant results on the surface.
The word "Button" does not exist in the email body, subject or attachments of most of the results returned.
I did some more testing with the word "Button". Emails were returned with no attachments and the word "Button" is not in the email. I forwarded one of the returned results to myself but it did not have "Button" in the message header either.
I have proven the following so far:
-This happens in and out of cached Exchange Mode (a re-index had already been tried but this proves that indexing is not the problem)
-This happens after an index rebuild.
-This happens in two different Outlook clients, at two different locations, in two different versions of Outlook (2010, 2016)
-This happens when searching an exported pst and not just the mailbox (proving that this isn't an Exchange Issue)
-The word is not present in the message body, attachments or email header
-This issue occurs on other users machines
Using advanced find I found that the word "Button" was being returned in the Frequently used field "Message" and no other fields. Yet, when opened the search results, I could not see the word highlighted.
Does anyone have any ideas?
