Office365 Office 2016 Version 1702 (Build 7870.2024) update breaks Outlook search

Edit: As of 27/03/2017 Microsoft has released Build 7870.2031 of Office 2016 which appears to have fixed the issue. It has for me anyway.

Recently Office 2016 updated itself (Office365 subscription so it uses ClicktoRun) to version 1702 (Build 7870.2024) and this appeared to break searching emails in Outlook 2016.

I thought that maybe the index was corrupt, so I tried triggering a rebuild, but this did not resolve the issue.

To see what version you’re running, have a look in the Account section of a programme in the Office Suite. For example, in Excel open a blank workbook, then click on File on the ribbon, and choose Account in the list on the left-hand side:

There you can see it lists info about the current version, in this case Version 1702 (Build 7870.2024), and lets you alter update options.

As a temporary workaround I disabled automatic updates, and then rolled back to a previous version.

To disable updates, click on Update Options > Disable Updates. I’m in Windows 7, and I got a UAC prompt to confirm the action.

Click on Update Options > View Updates to get to the version history web page. This page shows what’s changed through the different versions. Scroll down near the bottom and you’ll see a Previous Releases section where you can look at the different versions released in previous months.

I decided to try going back just one version, which is listed as Version 1701 (Build 7766.2060).

In order to roll back to a previous version, open a command prompt, enter cd “%programfiles%\common files\microsoft shared\clicktorun” and hit return.

Now you can run the ClicktoRun client and tell it to update to a specific version (using the build number we found above; 7766.2060).

Type in OfficeC2RClient.exe /update user updatetoversion=16.0.7766.2060 and hit return. There won’t be any output in the command line to look at, you’ll just be taken back to the prompt:

Very soon, if not immediately, you should see something like this showing that updates are being downloaded:

Once it’s done, open Outlook and try a search. To start with I got a warning about the index not being complete, so I guess it triggered a rebuild.

In Windows 7 the indexing process slows down when it detects someone is using the computer but you can disable this if you find it is taking a long time to rebuild.

  1. Hi Tom,

    I hope you will excuse the intrussion but I just read your posting from Thursday, 21 November 2013 (old blog) about using SoftEther VPN on a Raspberry Pi and found it very interesting and helpful in de-mystifying some of the terminology and felt I should say “thanks”, “hello” and ask a question 🙂 I am not looking for a “how to” just a few pointers as I fear I might be about to atempt something impossible or at least very difficult given my level of limited understanding. From your blog posts you clearly have a much better understanding of these things than I do and with your obvious interest in the pi I hoped you might be able to offer some thoughts.

    From the opening lines on your Blog I see we also share a number of interests (amateur radio, computers and motorcycles) but my primary interest on this visit to your blog was the item about using SoftEther on a pi. I have to admit up-front my knowledge is nothing like as deep as your own when it comes to computers and software so please excuse the knieve questions.
    BTW, I am M0***, 60 years old and ride an old ZZR600 when the sun shines and the xyl is not around 🙂 If you want more details about my past ham activity then please feel free to contact me directly via e-mail.

    Just four years ago I had virtualy no knowledge of networking until I got my first pi and decided to have a go at making a stand alone wireless webserver. Software skills really do not seem to come natural to me Hi. I really struggled but after about a year of on-and-off playing about I managed to make a few web-pages and files available over a secured Wifi link from a pi and even managed to get a php script to shut down the pi at the press of a virtual “stop” button from a remoteley viewed web-page. Wow!

    So thats my humble acomplishment to date and while I am happy with the results I find I am now wanting to do more. My recent interest is in somehow connecting to a pi connected to my home router and sitting behind the home routers firewall. I know I could take the easy route (and probably should given my lack of skill) and just open-up a port on my home router but that seems like the easy way out and also (if I understand correctly) compromises security.

    After reading a little more about networking and how “NAT” works (and if I have even half understood) then a far more secure and more interesting approach is to use some sort of “tunneling” but I am not sure if thats even possible with a pi? I am aware of services on the Internet which offer such services (like VNC) but they all seem to rely on a centraly located server with all my traffic going through that server. While such services are convenient as regards keeping track of your changing home IP address etc I was wondering if such remote acess to my own pi might be possible without the need for a third party service?

    So, in conclusion I think what I am asking is “can a pi host a webpage or files behind a firewalled home router and still be made available for remote acess” ? I could just read a guide on setting up a “hidden service” but thats not really what I had in mind. I was looking to run one of my pi’s with a user friendly web-page filled with “virtual” buttons in order to remoteley control stuff in the shack but without the requirement of using a third part to provide the tunneling service. I wonder, is that posssible?

    If you have any thoughts, comments I would be interested to hear them.

    Best wishes & 73,s
