Exchange 2016 search problem. After upgrading our Exchange Server hardware the search function in Outlook and OWA are not working. The upgrade of the server was done by building the new server and performing mailbox moves from the old server to the new server. The search issue started immediately after the upgrade over this past weekend. I have noticed the issue on multiple network pcs in Outlook. In Outlook if a search is performed, it states "Something went wrong and your search could not be completed". When I try to search in OWA, it says "An error occurred while searching. Please try again later". Prior to testing a search in OWA (since no one in the company uses OWA), I had tried to do a re-index on one pc. Now that I see it is effecting multiple pcs and OWA, I am assuming it is a server level issue. Not sure how to resolve this.
Any help would be appreciated.
