Speeding Up the Groups and Teams Activity Report by Replacing PowerShell with Graph API Calls

Sometimes it’s wise to give PowerShell scripts a turbo boost. This is certainly true for the Groups and Teams Activity report script, where a large amount of PowerShell processing has been replaced with speedy Microsoft Graph API calls. The result is much faster processing, which means that the script is more useful in large tenants. I still wouldn’t try to run it against 100,000 groups, but anything smaller should be OK. I think!

Faster PowerShell ForEach Loops to Process Office 365 Data

PowerShell is a great way to get work done with Office 365 data. The downside is that PowerShell can sometimes be slow, which is why we look for ways to speed things up, especially when dealing with some of the “heavier” cmdlets like Get-UnifiedGroup.
