Fix: Windows 10 (Technical Preview) OneDrive Sync Issues with Office 2016 Preview

After installing the Office 2016 Preview on build 10074 of the Windows 10 Technical Preview I came across a recurring sync issue with OneDrive. All the Office documents would show up with the following error ‘Files can’t be synced. Open the document in Office for more info.’
It didn’t make any difference if you opened the document in Word, Excel and saved them back they would still show up with sync errors.

To fix the issue I turned off the ‘Use Office to sync files faster and work on files with other people at the same time’ from the Settings tab (right click the OneDrive icon on the status bar). An Exit and restart of OneDrive fixed the issue and everything comes up green again.

I’m guessing this is something to do with the Office 2016 preview since I’ve been running Windows 10 TP for a few months now and didn’t have any sync issues.

This not only fixed the sync issue but also made Office use the local files instead of taking a few seconds connecting to OneDrive each time I saved.

Script to Download Yammer Image Profile

Here’s a neat script I wrote the other day to download the urls of all the user’s in your Yammer network. This comes in handy when you want to re-use the profile images that users have uploaded to Yammer.

The advantage with this script is that you don’t need the app to be approved by your Yammer admin. Just create a user created app on Yammer, create a token and approve it for your profile. That’s it. The token can be re-used as long as necessary.

Here’s the PowerShell script that will get you there.

    This script downloads the profile image urls of all the users from Yammer, creates a csv file and uploads it to the YammerProfile document library.
    Example>    .\Download-YammerProfile.ps1 -YammerToken 05fdIb1pNwIFEBg9k34EWw -SiteUrl http://mysharepoint/site
    [Parameter(Mandatory = $True, HelpMessage='Yammer Access Token - Refer to for how to generate an access token. Eg. 05fdIb1pNwIFEBg9k34EWw')]
    [Parameter(Mandatory = $True, HelpMessage='The url of the site that will store the Yammer user profile list. E.g. http://mysharepoint/site')]

Function Main() {
    $documentLibrary = "YammerProfiles"
    $csvFile = "YammerProfiles.csv"

        CreateYammerProfileCsv $YammerToken $csvFile
        $spWeb = Get-SPWeb -Identity $SiteUrl #Refresh reference to avoid timeout issue when it takes a long time to download from Yammer
        UploadToSharePoint $csvFile $spWeb $documentLibrary

        Log "Download-YammerProfile.ps1 completed succesfully"
    catch {
        [string]$errDetail = $_.ToString()

Creating PDF files dynamically with PowerShell

So how does one go about creating PDF files dynamically? You need a pinch of the open source PdfSharp library and 10 lines of PowerShell.

Add-Type -Path .\PdfSharp.dll
$doc = New-Object PdfSharp.Pdf.PdfDocument
$doc.Info.Title = "Created dynamically"
$page = $doc.AddPage()
$gfx = [PdfSharp.Drawing.XGraphics]::FromPdfPage($page)
$font = New-Object PdfSharp.Drawing.XFont("Verdana", 20, [PdfSharp.Drawing.XFontStyle]::BoldItalic)
$msg = "Hello World"
$rect = New-Object PdfSharp.Drawing.XRect(0,0,$page.Width, $page.Height)
$gfx.DrawString($msg, $font, [PdfSharp.Drawing.XBrushes]::Black, $rect, [PdfSharp.Drawing.XStringFormats]::Center)

Creating jUnit/xUnit compatible xml test tesults in PowerShell

I originally wrote this function when I needed to create jUnit/xUnit compatible test results. The resulting xml file was then fed into the jUnit plugin in Jenkins to show the results PowerShell/PSUnit based tests.

Function Write-JunitXml([System.Collections.ArrayList] $Results, [System.Collections.HashTable] $HeaderData, [System.Collections.HashTable] $Statistics, $ResultFilePath)
$template = @'
<testsuite name="" file="">
<testcase classname="" name="" time="">
    <failure type=""></failure>

    $guid = [System.Guid]::NewGuid().ToString("N")
    $templatePath = [System.IO.Path]::Combine([System.IO.Path]::GetTempPath(), $guid + ".txt");

    $template | Out-File $templatePath -encoding UTF8
    # load template into XML object
    $xml = New-Object xml
    # grab template user
    $newTestCaseTemplate = (@($xml.testsuite.testcase)[0]).Clone()  

    $className = [System.IO.Path]::GetFileNameWithoutExtension($HeaderData.TestFileName)
    $ = $className
    $xml.testsuite.file = $HeaderData.TestFileName

    foreach($result in $Results) 
        $newTestCase = $newTestCaseTemplate.clone()
        $newTestCase.classname = $className
        $ = $result.Test.ToString()
        $newTestCase.time = $result.Time.ToString()
        if($result.Result -eq "PASS")
        {   #Remove the failure node
            $newTestCase.RemoveChild($newTestCase.ChildNodes[0]) | Out-Null
            $newTestCase.failure.InnerText = Format-ErrorRecord $result.Reason
        $xml.testsuite.AppendChild($newTestCase) > $null

    # remove users with undefined name (remove template)
    $xml.testsuite.testcase | Where-Object { $_.Name -eq "" } | ForEach-Object  { [void]$xml.testsuite.RemoveChild($_) }
    # save xml to file
    Write-Host "Path" $ResultFilePath
