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 ]

Find Whitelisted Users, Domains, and IPs in Office 365
If you’ve ever asked anyone how to do virtually anything, the answer is usually “It depends.” Just as there is no wrong way to eat a Reese’s Peanut Butter Cup and more than one way to skin a cat, so it frequently is with technological tasks. … [ Continue reading ]

Delegating Reporting Access for Exchange Online
Earlier this week, I had a request for assistance with delegating reporting features in Exchange Online to non-administrative users. This is a frequent topic of discussion when it comes to compliance and security officers validating that systems are not being misused by unauthorized persons.… [ 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 ]

Add legacyExchangeDN as x500 proxy address from a remote forest
The other day, on one of the forums, I came across an issue that I also had with one of my customers a few years ago. In my customer’s instance, they had imported thousands of contacts into an externally trusted forest and deleted them in their primary forest (which then removed the objects from Office 365). … [ 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 ]

Header, header, wherefore art thine fields?
Today, I got it in my head that I wanted to create a script that would accept CSV input. In so doing, I wanted to make sure the CSV passed some sort of validation so that I didn’t end flooding a screen with errors, because nobody likes that.… [ Continue reading ]

Update to the Create-LabUsers tool
While working on my last mini-series, I utilized my Create-LabUsers tool to automate the creation of a few thousand objects.

AAD Connect, a dedicated resource forest, a custom connector, and a bunch of transform rules: a GalSync story (Part 1)
A few years ago, I worked with one of my close consultant peers to build a GALSync-style solution for a big state government that was going through a divestiture from a single BPOS-D (yes, I am old) and a single managed hosted Exchange environment to multiple O365 multi-tenant instances. … [ Continue reading ]

Adding OneDrive Locations to an Existing Retention Policy
Yesterday, while working with a customer, I was asked if there is a way to programmatically add OneDrive locations to an existing retention policy. Say, for example, you have a blanket retention policy that covers all of your tenant at a base level (which is what I typically recommend to ensure you at least have either belt or suspenders), but then you have a second set of users that need a longer policy.… [ Continue reading ]
