Delete OST file and run outlook process - forms

Question

I have a form that im using to delete a ost file in powershell then starts outlook. I think the process to start outlook is opening quicker than the ost can be deleted. Here's what i have.
taskkill.exe /im outlook.exe /f
$OstPath = $Env:LocalAppData + "\Microsoft" + "\Outlook"
$ost = get-ChildItem $OstPath | where { $_.Extension -eq ".ost"}
$ost | remove-Item
Wait-Job $ost
Start-Process -FilePath "C:\Program Files\Microsoft Office 15\root\office15\outlook.exe"

Answer 1

This is the function i came up with and works really well with Office 2013 and Office 2016:
Function RebuildEmail
{
#COMMENT: Stops all Outlook process' and deletes .ost file then prompts to run setup.
$a = new-object -comobject wscript.shell
$intAnswer = $a.popup("This will stop Outlook and Skype for Business,`nRemoves the local copy of your email and will resynchronize from the exchange server. Be sure you have a steady internet connection! . `nDO YOU WANT TO CONTINUE?", `
0,"Service Desk",4)
If ($intAnswer -ne 6) {
$a.popup("Please call the Service Desk for support.")
} else {
$a.popup("Rebuilding will begin...")
Stop-Process -Name ("Outlook", "Lync")
$n = 0
Do
{
If(Get-Process -Name ("outlook", "Lync") -ErrorAction silentlycontinue)
{
Stop-Process -Name ("Outlook", "Lync") -ErrorAction SilentlyContinue
If ($n -lt 5)
{
$ExitLoop = $false
$n++
Start-Sleep -Seconds 3
If($n -eq 5){$ExitLoop = $true}
}
}
else {$ExitLoop = $true}
}
While ($ExitLoop -eq $false)
if ($n -ne 5)
{
$OstPath = $Env:LocalAppData + "\Microsoft" + "\Outlook"
$OSTs = Get-ChildItem $OstPath | where { $_.Extension -eq ".ost"}
$OSTs | Remove-Item
Start-Sleep -s 3
foreach ($ost in $OSTs)
{
$FilePath = $OstPath + "\" + $ost
$n = 0
Do
{
if(Test-Path $FilePath)
{
Remove-Item $FilePath
Start-Sleep -Seconds 5
$ExitLoop = $false
$n++
if($n -eq 5){$ExitLoop = $true}
}
else {$ExitLoop = $true}
}
While ($ExitLoop -eq $false)
if($n -ne 5)
{
$a = new-object -comobject wscript.shell
$intAnswer = $a.popup("The local copy of your email was successfully removed.", `
0,"Service Desk",0)
}
else
{
$a = new-object -comobject wscript.shell
$intAnswer = $a.popup("Unfortunatley, your local copy couldn't be removed. Please call the Service Desk.", `
0,"Service Desk",0)
}
}
}
else
{
$a = new-object -comobject wscript.shell
$intAnswer = $a.popup("Outlook was unable to close. Please call the Service Desk.", `
0,"Service Desk",0)
}
Start-Process -FilePath "C:\Program Files\Microsoft Office 15\root\office15\outlook.exe" -ErrorAction SilentlyContinue

Start-Process -FilePath "C:\Program Files (x86)\Microsoft Office\root\Office16\lync.exe" -ErrorAction SilentlyContinue
Start-Sleep -s 30

$intAnswer = $a.popup("Please allow a few minutes to update folders. Call the Service Desk if issue persist.", `
0,"Service Desk",0)
}
}
