We recently had to perform the year-end tasks in Teams/SchoolDataSync which should be easy really – run through the cleanup process to archive all of last year’s teams, then update the SDS profiles with the new term dates, and resume syncing with the new data. Unfortunately ours messed up and removed all members from the archived teams – presumably as I forgot to hit “Reset Sync” before feeding it the new year’s data.
Luckily there’s a solution to get these memberships back – we need to go and search the Azure AD audit log for group membership removal events. Head to the Compliance Admin Centre > Audit > Audit Search, and search for the activity “Azure AD group administration: Removed member from group”. Put the date range in, and click Search. You should hopefully get some results, all performed by the ServicePrincipal account. If you click onto one of these results and examine the data, you’ll notice we can discover the username, team name and the team’s group ID, which is all contained in the JSON formatted data associated with the log entry.

There’s been a Group Policy setting to sync Team/SharePoint libraries for a while although last time I looked at it the functionality didn’t actually work yet – I think it was meant to be available from Windows 10 1909 but didn’t quite make it. Besides the fact that the setting didn’t do anything, all the documentation claimed it could take “up to 8 hours” for the library to appear in the user’s sync client/Explorer – clearly this is no use especially if you’re in an environment where people hot desk and share machines. I’ve had another look at it to see if it’s any better now.
I don’t like things that can’t be automated. I started looking at School Data Sync (SDS) last year, however the templates provided by iSAMS, which is our school Management Information System, just gave a set of CSVs and you had to manually click to get them, then click to upload them into SDS. Since iSAMS has an API, I thought this was a bit of a silly way of doing things – who wants to go through a manual process every time a pupil changes class? So instead I wrote my own powershell to pull the data through the iSAMS API, then run through the New-Team cmdlet to create a team per class, and populate it with teachers and students.
As we’re a school we need our new teams to be running the Edu_Class template, but the template parameter on New-Team only exists in the preview (and in Graph, on the beta endpoint) where it has much harsher limitations on how often and fast you can call it – a nightmare trying to call it in a loop. Anyway with the addition of “Start-Sleep 30” in the loop I eventually got them all created. However this time I am having another look at SDS and using Power Automate (previously known as Flow) to make the process completely automatic.
(Updated 4th Sept 2020: Use New-CsBatchPolicyPackageAssignmentOperation instead of Grant-CsUserPolicyPackage now)
I’ve recently needed to apply a PolicyPackage to a group of users (well 2 packages to 2 groups) using PowerShell – as the Teams Admin centre only allows you to apply to users by typing in all the names one at a time and pressing Add and discovered the New-CsGroupPolicyAssignment cmdlet, which looks good – however this applies a policy to a group, but I want to apply a policy package.
