Backup permissions for Sharepoint Online

So you have started down the road of creating your Sharepoint site in Office 365 but you do not have permissions permissions as these require to be manually added.

We are a little lazier than that, this will be the basis of a scheduled job.

Please use the script below along with my small recommendations:

#one-time generation of an a file to hold password so that we may schedule the job. 
#read-Host “Enter Password” -AsSecureString |  ConvertFrom-SecureString | Out-File “C:\Scripts\o365_spo.txt”

Import-Module Microsoft.Online.SharePoint.PowerShell -DisableNameChecking

#Setup our variables
$date = (get-date -format "dd-MM-yy")
$contents = $null
$emailbody = $null
$AdminURL = ""
$AdminName = ""
#admin account we will be adding
$AdminNames = "",""
$TenantPass = cat “C:\Scripts\o365_spo.txt” | ConvertTo-SecureString
$TenantCredentials = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $adminname, $TenantPass
$cred = [System.Net.CredentialCache]::DefaultCredentials
[System.Net.WebRequest]::DefaultWebProxy.Credentials = $TenantCredentials

Connect-SPOService -Url $adminurl -credential $TenantCredentials

#Build site list
$Sites = Get-SPOSite -Limit ALL

$emailbody = "<HTML><HEAD><META http-equiv=""Content-Type"" content=""text/html; charset=iso-8859-1"" /><TITLE></TITLE></HEAD>"
$emailbody = "<BODY bgcolor=""#FFFFFF"" style=""font-size: Small; font-family: Arial; color: #000000""><P>"
$emailbody += "<p>Please be aware that the following permissions have been added to sharepoint sites by $AdminName :</p>"
$emailbody += "<p>Tenancy: $AdminURL</p>"

Foreach ($admin in $adminnames){

    Foreach ($Site in $Sites){
        Set-SPOUser -site $Site.Url -LoginName $Admin -IsSiteCollectionAdmin $True
        $displayname = Get-SPOUser -site $Site.Url -LoginName $admin
        $displayname = $displayname.displayname | out-string
        $url = $site.url | Out-String
        $isadmin = get-spouser $site.url -loginname $Admin | select issiteadmin
        $emailbody += "$displayname confirmed as $isadmin for: $url</br>"
        write-host $emailbody
$emailbody += "<p>Regards,</p>"
$emailbody += "<p>Your friendly Office 365 team</p>"
