Tuning PowerShell for Office 365 Group Membership

A recent article prompted a check to see whether a PowerShell recommendation made sense and delivered better performance when executing a command to extract the membership of Office 365 Groups performance. As it turns out, the recommendation is valid, but whether you notice any difference is arguable.

New OWA Maturing in Different Ways

The new version of OWA is maturing and new features are turning up on a weekly basis. You can now schedule a Teams meeting from OWA and the prospect of joyful animations hang in the air. But only for Office 365 users as there’s no sign that the new OWA will come to Exchange on-premises servers.

Office 365 Network Performance (POC) Tool

Microsoft’s new Network Performance Tool is a proof of concept for Office 365 tenants to check network connections to Microsoft’s network and Office 365. The tool might help you understand more about your connection into Microsoft, but it won’t fix any last mile problems.

How to Post Information to Microsoft 365 Groups or Teams Channels

It’s easy to create a webhook connector to post information to a team channel or an Microsoft 365 group. What might not be quite so easy is formatting the JSON payload. Here’s how to use a template card to simplify the process.

The Dangers of Cut and Paste Technology Coverage

We all make mistakes – it’s part of life. But it’s sad that so many web sites and blogs pick up and repeat mistakes found in press releases and other material. Life would be better if we had more time to consider what we publish, but the speed of the cloud sometimes makes time hard to find.

Service Domain Prefix Appears and Disappears in Exchange Online Cmdlets

A change made to fix a problem in Exchange Online introduced another problem in that service domains started to show up as prefixes in the data returned by PowerShell cmdlets. Microsoft has reversed the change, but the way things happened creates some questions.

Applying Autosignatures with Transport Rules

Office 365 tenants can use Exchange transport rules to apply autosignatures to outbound email, including messages protected with encryption. You can even include some properties of the sender extracted from Azure Active Directory, and you can add an exception so that the autosignature isn’t applied to replies.

Using Exchange Session Identifiers in Audit Log Records

Exchange Online now captures session identifiers in its mailbox and admin audit records that are ingested in the Office 365 audit log. That’s interesting and useful, but how do you access and interpret this information on a practical level?

How to Create Global Contacts in an Office 365 Tenant

You can use a public folder to store and share global email contacts, but a better approach is to use Exchange mail contacts. These objects show up in the Exchange GAL and OAB and are available to all Outlook clients (and some third-party clients too).

Sending Email with PowerShell and Exchange Online

You can use the Send-MailMessage cmdlet in a PowerShell script to send mail messages via Exchange Online. And sometimes your IP address might be listed as a spammer, which is bad. All in all, authenticated client submission seems best.

Sending Protected Email to Teams, Yammer, Groups, and Shared Mailboxes

Encrypted email is becoming more common within Office 365. Things usually flow smoothly when sending protected messages to email recipients, but other Office 365 recipient types like Teams and Yammer might not be able to handle protected email.

Azure Active Directory Feature Bans Custom Words from User Passwords

Making sure that Office 365 user (and administrator) accounts have good passwords is a never-ending task. A new preview feature in Azure Active Directory helps by ensuring that users can’t include common words specific to the organization (like its name) in a password. It’s another piece in the puzzle to frustrate potential attackers.

Searching for Encrypted Office 365 Information

Making it easy to protect Office 365 content with encryption is great, but it has some downsides too. One of the obvious problems that we have is that encrypted documents in SharePoint and OneDrive for Business libraries can’t be found unless their metadata holds the search phrase.

Protected PDFs Now Generally Available with Microsoft Information Protection

The Microsoft-Adobe initiative to support Azure Information Protection for PDF files has reached general availability. Things look good and the issues encountered in the preview are removed. You can store protected PDFs inside Office 365, but be prepared to download the files to be able to view them.

How to Track the Processing Done by Exchange Online’s Managed Folder Assistant

The Exchange Online Managed Folder Assistant (MFA) runs in the background on a workcycle basis to make sure that mailboxes are processed at least once a week. Most of the processing involves mailbox and Office 365 retention policies and runs smoothly, but how do you know what MFA has done?

Report for Email Encryption in the Security and Compliance Center

The Office 365 Security and Compliance Center includes a report to detail encrypted email. The report is in preview. It’s a nice insight into user activity, even if it has some glitches that need to be sorted out before it becomes generally available.

How to Use PowerShell to Report Retention Policies for SharePoint Online Sites

Knowing how retention policies process Office 365 data can be hard to understand, especially if multiple policies are involved. Office 365 doesn’t give a global view of how retention policies affect workloads, but here’s how to use PowerShell to find out what policies process the sites in a tenant.

Logos in Email – Another Way to Stop Spoofing

Including a company’s logo when listing or displaying email is another way to give users confidence that the email is in fact from that company. Business Indicators for Message Identification is a draft standard that might become generally used by all email clients. But for now. Microsoft has their own business profile “brand card” program, and that’s where OWA gets its logos.

How to Report the Connection Protocol Used by Outlook Mobile Clients

Microsoft has refreshed the Outlook Mobile architecture (now called “Microsoft Sync Technology”). They suggest that you run some PowerShell to report clients connecting via the old and new architectures. Their code works, but we think ours is better.

Understanding the Email Addresses Used by Microsoft 365 Groups and Teams

Some recent questions in the Microsoft Technical Community show confusion about the email addresses used by Office 365 Groups and Teams. Here’s our attempt to clarify.

Using S/MIME with the Azure Information Protection Client

The latest version of the Azure Information Protection (AIP) client supports the ability to associate S/MIME protection with an AIP label. Although interesting, it’s a feature unlikely to be of much practical use to the majority of Office 365 tenants.
