I have what seems to be a unique issue that is starting to grow.
We moved from an Exchange 2007 backend to 2013 (v15.0, build 1395.4) a little over a year ago. We have about 1600 mailboxes and 3 databases. This was built by a 3rd party vendor and I am the one maintaining/administering it. It is NOT my primary focus at
my job so my knowledge is a bit limited, but I have been tasked to dedicate more of my time to try and fix this issue.
What is starting to happen is that our helpdesk is receiving more and more calls about searching not yielding good results. I spent time with them yesterday and worked with a new user, only been in our system for about a month and has a pretty small mailbox,
who was attempting to find an email from last week and searched a word that he knew was in the subject and it did not return the email he was looking for. This is in Outlook 2007. Yes I realize this is old and dated, but its all I have to work with. He then
tried in Outlook 2013 (which we dont widely publish, just gave him temp access to) and it returned different results but still not the original email that he was looking for. I then had him try OWA and the way it displays search results is different, basically
lumps the entire conversation into one thread and he was then able to expand that thread and see the original email he was looking for.
Another example is someone else in our IT department was looking for an email from "Sarah". She searched for an email that was in her inbox from yesterday and it didnt come up in her search. She then tried OWA and it too did not return the email
she was looking for.
Searching for most things works, but more and more calls from users are coming into the helpdesk with various searching issues and I am not sure where to start since they are so intermittent. It doesnt help the our CIO has been having searching issues for
about a year now and now that there are more popping up, he wants me to look into it further. Any help would be greatly appreciated. I am willing to try anything and will take all suggestions into consideration. If any suggestion will take mail down and require
downtime, obviously with proof that it will work/help, I will be able to coordinate that with our CIO and office managers.
