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.

Enabling Rec. Playback audio recording device on a Dell M6600

I wanted to pull a snippet of audio from a video I was watching in my browser to send to someone, but couldn’t find a suitable recording device listed to allow me to do this easily. A lot of sound cards support this feature and will have a recording device called Stereo Mix, or Rec. Playback, or Record What You Hear, or something similar. Using the device allows a program to record any audio that is playing on the machine. After a bit of head scratching and some googling, it became apparent that the features you are allowed to use are determined by the drivers that ship with the machine.

The Dell M6600 has an IDT High Definition Audio CODEC sound card. There is a basic driver, provided by Microsoft, that gets installed automatically when installing Windows 7. This driver does not allow access to the Rec. Playback device that is available on the sound card.

A look on the dell support website did not turn up any results, at first. For some reason known only to Dell they don’t list any audio drivers unless you scroll down and choose the option to browse all available drivers for the M6600. Then an Audio category appears in the list, with a link to a page that provides a driver by IDT.

I downloaded the driver, installed it, rebooted, and then Rec. Playback appeared as a recording device.
