Hi All,

I’ve had a customer that wanted to disable the Viva Insights Outlook Add-In

I did check the M365 Admin Center > Settings > Org Settings > Microsoft Viva Insights > Everything was disabled

I’ve checked the M365 Admin Center > Settings > Integrated Apps

I’ve checked with PowerShell

Connect-ExchangeOnline -ShowBanner:$false
Get-VivaInsightsSettings -Identity a.bohren@icewolf.ch
Get-MyAnalyticsFeatureConfig -Identity a.bohren@icewolf.ch | fl

DefaultTenantMyAnalyiticsFeatureConfig

Get-DefaultTenantMyAnalyiticsFeatureConfig

Found the OrganizationApp with the Help of Microsoft

Hi All,

A few Months ago i saw, that the recommendation for New-ApplicationAccessPolicy has changed.

App Access Policies are replaced by Role Based Access Control for Applications. To learn more, see Role Based Access Control for Exchange Applications. Don’t create new App Access Policies as these policies will eventually require migration to Role Based Access Control for Applications.

In Github you can see that the Change has been Published in August

Hi All,

I write this Article about Distribution Group Manager in Exchange Server for two reasons

• First: I want to point out, how it’s represented in Exchange Server and actually stored in Active Directory
• Second: I’ll explain why Exchange Online Users can’t manage Group Members in Outlook anymore

This is absolutly not anything new. Distribution Group Manager exists at least since Exchange Server 2010 or maybe even longer - honestly i don’t remember
