Exchange Online to Enable Plus Addressing Everywhere in January 2022

Microsoft has announced their intention to enable plus addressing across Exchange Online in January 2022. Plus addressing is a good capability, but it might cause some problems for tenants with mail-enabled recipients that have plus addresses in their set of proxy email addresses. Fortunately, we've written some PowerShell code to report those pesky addresses and to remove them if you want to do a big clean up before Microsoft makes the big switch in five months' time.

Upgrading PowerShell Scripts with Azure AD Cmdlets to Use Graph API Calls

Microsoft has announced that they won't support the Azure AD Graph after June 30, 2022. This means that the Azure AD PowerShell module won't be supported either. With that in mind, it's probably a good idea to think about how to upgrade scripts to use Graph API calls instead of Azure AD cmdlets.

It's all the housekeeping beforehand that takes the time.

Using Filters with the Get-ExoMailbox Cmdlet

It's a good idea to replace older calls to the Get-Mailbox cmdlet with Get-ExoMailbox. However, it's not just a matter of cut and paste updates. In some cases, the nature of the new REST-based cmdlets mean that some additional care is necessary to ensure that the updated code works as expected.

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..

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!
