About a month ago, I wrote a script in Powershell to harvest user detail usage data from Skype for Business daily. At the time that I wrote it, the script successfully pulled data down and logged it to a csv file. Now, when I run this script, the API call successfully executes and returns the reporting headers, but does not return any data. Has anyone noticed any stability problems with using SkypeForBusiness reporting endpoints?

code for reference:

    $redirectUrl = "https://localhost:8000"

$GraphAPIURI="https://graph.microsoft.com"

$client_id = "app-id"

$client_secret = "app-secret"

$delimiterHeader="sep=;`n"



$D7UserDetailOutput= "D7UserDetail.csv"

$D30UserDetailOutput= "D30UserDetail.csv"

$D90UserDetailOutput= "D90UserDetail.csv"

$D180UserDetailOutput= "D180UserDetail.csv"
