Creating Personal Contacts in User Mailboxes with PowerShell and the Graph

An earlier article explained how to create organizational contacts in user mailboxes with Graph API calls. This article builds on that idea with three improvements. First, we select target mailboxes for update by looking for those added in the last month. Second, we allow any mail-enabled recipient to be added as an organizational contact. Third, we incorporate some code to check if a contact already exists in a mailbox. Like anything with PowerShell, this code can be improved..

Microsoft Delays June 2021 Cumulative Update for Exchange Server

Microsoft has delayed the release of the June 2021 cumulative updates for Exchange Server for two weeks to integrate the Windows Antimalware Scan interface (AMSI). The change will allow Exchange 2016 and Exchange 2019 servers running on Windows Server 2016 or later to integrate antimalware engines to check HTTP requests for potential problems. If ever there was good reason to delay an update, this is it.

How Outlook’s Room Finder Uses Metadata from the Places Service

The Outlook Places service uses metadata stored for conference rooms and room lists to help users find suitable meeting places. The metadata surfaces in Outlook's Room Finder component (shared between OWA and Outlook desktop). Obviously, the better populated the room metadata is, the more useful it will be, once we all start meeting in conference rooms again!

Moving on from Send-MailMessage: Sending Email from PowerShell using the Graph API

Many PowerShell scripts use the Send-MailMessage cmdlet to send mail. That's fine, but if you want to remove basic authentication to improve tenant security, you need to stop using Send-MailMessage. One solution is to move to use the Graph API SendMail call. This works fine, but it creates some new security issues that need to be thought through. In this article, we explain how to use the Graph to send email and some of those security considerations to ponder.

Getting Exchange Online Distribution List Membership Counts with PowerShell

It's important to know if a tenant has any very large distribution lists as these might be the source of reply-all mail storms. An old article explains how to report the membership counts for distribution lists on an on-premises Exchange server. Life is different in the cloud, and we need to take a different approach. This article explains how to use different calls in a PowerShell script to create a nice report about distribution list memberships.

Deploying Custom Teams Group Policy Assignments

Deploying Custom Teams Group Policy Assignments

Microsoft Teams uses an array of policies to control the features available to end users. Group policy assignments make it easier to assign packages of policies to groups of users. Microsoft provides a set of policy packages out of the box, and organizations can create custom packages. That is, if they have the Teams Advanced Communications license. Demanding a special license for functionality which helps tenants manage Teams better seems excessive, especially as you could relatively easily recreate policy assignments with PowerShell.

Upgrade Your Exchange Online Scripts to Use the Get-EXOMailbox Cmdlet

Many Exchange Online scripts use the old Get-Mailbox cmdlet to fetch mailbox data. It's time to change these calls out and replace them with Get-ExoMailbox. The new cmdlet is faster than the old and more resilient in its ability to handle server glitches. There's no reason to continue using the old Remote PowerShell cmdlets unless you like slowness and errors.

Microsoft Extends Teams Retention Policies to All Licensed Office 365 Accounts

Microsoft announced a bunch of changes for Microsoft 365 records management on May 19. The most interesting changes are allowing all licenses Office 365 accounts to use Teams retention policies and the advent of adaptive scopes for retention policies, both of which should be useful for many tenants. The announcement also covers multi-stage disposition reviews. If you know what that means, you'll be excited. If not, you won't.

Microsoft Updates Outlook to use Advanced Settings for Sensitivity Labels

Updates to Outlook clients (desktop, mobile, and OWA) respect the advanced settings in label policy which previously needed the deployment of the unified labeling client. Many organizations want to use mandatory labeling, but have been frustrated because of the lack of support in the Office applications. Now support is available, so it's time to label that email!

Microsoft Updates Viva Insights App with Wellbeing Features

A new version of the Microsoft Viva Insights app for Teams includes some of the promised wellbeing functionality designed to help stressed users get through the work day more easily. You can praise co-workers, learn to breathe and relax, note your current state of wellness, and take a virtual commute to wrap up the working day. Some people will love the app, others will wonder what the fuss is all about. It's a very personal thing, which I guess is the nature of Viva Insights.
