#Parameters for Creating New Site Collection in SharePoint Online
param ($strNewSiteUrl, $strNewSiteTitle,$strNewSiteOwner,$strNewSiteQuota,$strNewSiteResourceQuota, $strNewSiteTemplateID, $strTenantAdminURL,$strTenantAdminName)

# Reading password in the PowerShell window
$password = Read-Host “Please enter the password for $($strTenantAdminName)” -AsSecureString
# Settingup the credentials
$credentials = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $strTenantAdminName, $password
#Connecting to to SharePoint Online
try {
Connect-SPOService -Url $strTenantAdminURL -Credential $credentials
write-host “Report: Connected succesfully to SharePoint Online !!!” -foregroundcolor green
}
catch {
write-host “Error: Could not connect to SharePoint Online !!!” -foregroundcolor red
Break SPO-CreateNewSiteCollection
}
#verifying incase the site collection is already exists in SharePoint Online
$siteExists = get-SPOSite | where {$_.url -eq $strNewSiteUrl}
#verify if site collection exists even in the recycle bin
$siteExistsInRecycleBin = get-SPODeletedSite | where {$_.url -eq $strNewSiteUrl}
#Creating Site Collection by validting flag bits for above 2 scenarios
if (($siteExists -eq $null) -and ($siteExistsInRecycleBin -eq $null)) {
write-host “Report: Creating Site Collection $($strNewSiteTitle)” -foregroundcolor green
New-SPOSite -Url $strNewSiteUrl -title $strNewSiteTitle -Owner $strNewSiteOwner -StorageQuota $strNewSiteQuota -NoWait -ResourceQuota $strNewSiteResourceQuota -Template $strNewSiteTemplateID
}
elseif ($siteExists -eq $true) {
write-host “Report: $($strNewSiteUrl) already exists” -foregroundcolor red
}
else {
write-host “Report: $($strNewSiteUrl) still exists in the recyclebin” -foregroundcolor red
}
write-host “Report: Site Collection $($strNewSiteTitle) Created Successfully !!!” -foregroundcolor green
}
try {
# variables that are needed to host the new Site Collection
$strNewSiteUrl = Read-Host “Please enter URL for new Site Collection:: ex: https://onlysharepoint2013.sharepoint.com/sites/testSite”
$strNewSiteTitle = Read-Host “Name of New Site Collection:”
$strNewSiteOwner = Read-Host “Provide Admin account for new Site Collection:”
$strNewSiteQuota = 1000
$strNewSiteResourceQuota = 50
$strNewSiteTemplateID = Read-Host “Provide site Template-ID ex:STS#0”
$strTenantAdminURL = Read-Host “Provide Admin host URL: ex:https://<<tenant Name>>-admin.sharepoint.com/”
$strTenantAdminName = Read-Host “Provide Admin account ex:<<admin-user>>@<<tenant.onmicrosoft.com”

SPO-CreateNewSiteCollection -strNewSiteUrl $strNewSiteUrl -strNewSiteTitle $strNewSiteTitle -strNewSiteOwner $strNewSiteOwner -strNewSiteQuota $strNewSiteQuota -strNewSiteResourceQuota $strNewSiteResourceQuota -strNewSiteTemplateID $strNewSiteTemplateID -strTenantAdminURL $strTenantAdminURL -strTenantAdminName $strTenantAdminName
