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.

Taming Teams Notifications

There are several areas where Microsoft could improve the way Teams handles out-of-office and away-from-work scenarios. Are the default "quiet hours" reasonable? Should there be a global setting for quiet hours or do-not-disturb? While there may be good reasons to leave some of these as a tenant-level settings, you don't want to forget about the extra steps you must take to truly escape from Teams for a bit.

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 6 Comments

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.

Prepopulating Outlook Contacts with the Graph API

When contacts are added to an organizations Global Address List (GAL), they do not always populate in the users personal device contacts depending on what app, device, etc. is being used. This becomes problematic when users working from outside the office are unable to contact the IT Service Desk, HR, or other internal services. To solve the problem, this article introduces a PowerShell script that will read a set of standard contacts from a CSV file and write them as personal contacts to user mailboxes. Mobile devices can then synchronize these contacts along with others created by the user.
