Why the Last Login Date Reported by the Get-MailboxStatistics Cmdlet is so Wrong

with 0 Comments by

The venerable Exchange Get-MailboxStatistics has been around for over ten years, but now it’s telling lies about Office 365 users. Well, just the last login date to their mailbox. The problem is that the world is a very different place to when Microsoft first introduced PowerShell in Exchange 2007. Mailboxes didn’t get so many visits from mailbox assistants then…

Why PowerShell is a Core Skill for Office 365 Administrators

with 0 Comments by

PowerShell is a critical skill for Office 365 tenant administrators. A knowledge of PowerShell allows you to fix things that Microsoft leaves undone in apps like Exchange Online, SharePoint Online, and Teams. Sure, black holes exist for PowerShell (like Planner) and it is slow to process thousands of objects, but there’s nothing like a little script for getting things done.

The Evolution of Microsoft’s Collaboration Story for Office 365

with 0 Comments by

Since Office 365 appeared in 2011, Microsoft’s collaboration story has varied according to whatever technology is available. Originally based on Exchange and SharePoint, it’s gone through Yammer, Office 365 Groups, and now Teams. You’d be forgiven for being confused by the frequent changes in the strategy du jour. And now we have inner and outer loops to consider, at least according to Microsoft’s favorite collaboration slide. Here’s my take.

Recovering Deleted Email with New Exchange Online Cmdlets

Exchange Online has two new PowerShell cmdlets to help administrators recover deleted email on behalf of users.

Monitoring the Removal of Office 365 Groups (and Teams)

with 0 Comments by

Owners of Office 365 Groups can delete groups if they want. Some don’t like this as it means that SharePoint site collections, teams, and plans are removed.

In this post, Tony looks at some of the changes that happened in the last week or so that you might have missed, including Teams, Planner, OneDrive, Yammer, and Exchange. And preparation for GDPR…

Using the Office 365 Groups Naming Policy

with 0 Comments by

One of the premium features for Office 365 Groups is the ability to use a naming policy so that all groups (and Teams) have a compliant name. The policy is a nice-to-have feature if you are concerned about having a well-organized directory with all your groups gathered in the same place. The question is whether enough business value is gained from a naming policy to make it worthwhile.

The Mysterious Files Folder and its Importance to Office 365 Apps

with 0 Comments by

Many differences exist between the on-premises and cloud worlds. The Files folder is one of Office 365’s unique features. The folder exists in user mailboxes to hold information about “file-oriented experiences.” As it turns out, apps like Delve, SharePoint, and Office 365 Groups like to display file information to users, but they need a fast and efficient way to get to that data. Files is the answer!

You know that Office 365 Groups have a mailbox and that the mailbox holds conversations and the group calendar. But many other folders exist in a group mailbox. Some are used for internal purposes, some by clients. And sometimes you want to look to see what those folders hold, as when some mail might have been misdirected to Junk Email.
