Update to the Get-UserHoldPolicies Tool

A new year, a new update for Get-UserHoldPolicies!  Woo!

I stumbled across some additional information today regarding deciphering hold policies for mailboxes while troubleshooting another issue and decided to update my Get-UserHoldPolicies tool to reflect it.

The core pieces that I added:

  • Identifying Skype policies (as prefaced by sky in the InPlaceHolds property of a mailbox)
  • Identifying excluded mailbox policies (as prefaced by -mbx in the InPlaceHolds property of a mailbox)
  • Disposition action for items at the end of a retention period:
    • Delete only
    • Do nothing after retention period
    • Delete after retention period

You can see a few of the new options here. … [ Continue reading ]

Searching the Office 365 Unified Audit Log for Specific Activities, Sites, and Users

Last week, I was working with a large government customer in a consolidated tenant (read: all agencies in a single, centrally-managed tenant).  One of the questions that was presented was how to search and filter the audit log for entries relating to the following categories:

  • Files shared by an agency or department’s users
  • Files accessed in an agency’s SharePoint site collection

To that end, I based together this script. … [ Continue reading ]

Iterating hash values to a log file

While working on my last script, I was trying to figure out the best way to write the values stored in a hash table for the purposes of splatting out to a log file.

Consider:

$parameters = @{}
$parameters.Add("Parameter1","Value1")$parameters.Add("Parameter2","Value2")$parameters.Add("Parameter3","Value3")

$parameters = @{}; $parameters.Add("Parameter1","Value1"); $parameters.Add("Parameter2","Value2"); $parameters.Add("Parameter3","Value3")

I was using a modified version of my logging function, which is basically a wrapper for Add-Content with parameters for log detail/types, colors, and output display.… [ Continue reading ]

Migrating from Exchange Online eDiscovery and In-Place Hold to the Security & Compliance Center

One of the issues that some of my larger customers have been dealing with is the lack of tooling and planning around moving legacy Exchange Online In-Place eDiscovery & Holds to the new(ish) Security & Compliance Center.  Our direction has been to either let them age out or manually recreate them the Security & Compliance Center.… [ Continue reading ]

Alerting on OneDrive Deleted Item Activity

I had a customer recently raise some questions about how to provide further enhancements and protections around their OneDrive for Business deployments.  Suppose this scenario exists:

  • Users are site collection administrators over their OneDrive for Business sites (default configuration)
  • Retention policies are configured, but may only be configured to provide a very minimal amount of data protection (such as 90 days from creation or last modification of data) due to organizational legal compliance
  • No retention policies are in effect for the target data (as all the data we’re concerned with is technically older than 90 day creation or last modified date)
  • Malicious or disgruntled user deletes OneDrive data
    • Deletes data in OneDrive
    • Empties recycle bin
    • Empties second stage recycle bin

At this point, for any data older than 90 days, it is lost.… [ Continue reading ]

Migrate-EOPSettings now does ATP!

ATP! ATP!

At long last, I’ve made a first pass at updating the Migrate-EOPSettings script to now include settings for Advanced Threat Protection.  I’ve had several customers moving their instances from commercial EOP to Office 365 GCC, and while my Migrate EOP script would capture just about everything, it came to my attention that we still had configuration to do for ATP. … [ Continue reading ]

SharePoint Online and OneDrive for Business Custom Sharing Controls

Today, we’re going to explore two relatively new sharing controls in SharePoint Online (and, by extension, OneDrive for Business).  The two options we’re going to look at are located inside the SharePoint Admin Center (https://<tenant>-admin.sharepoint.com) under Sharing:

Overview

To test both of these functions out (as well as how other users are affected), I’m going to work with 3 test users and two security groups.… [ Continue reading ]

AAD Connect, a dedicated resource forest, a custom connector, and a bunch of transform rules: a GalSync story (Part 2)

In part 1 of our adventure, we built an Azure AD lab to support configuring AAD Connect to work as a GalSync engine. In this post, we’ll finish up the configuration.  As a reminder, this is the what the overall solution will look like:

And, as I mentioned in part 1:

Please don’t call Premier asking for support on this.[ Continue reading ]
