I got caught up in doing this, and now it’s 3:45AM. C’est la vie! My loss of sleep is your threat analysis gain.
I’ve made several updates to the PwnCheck tool (used to query the HaveIBeenPwned.com database).
Here they are, in no particular order!… [ Continue reading ]
Today, I was updating a script I wrote a while ago, and I wanted to streamline the processing loops once input was received. This particular script took parameters for:
- Identity (as an email address or UserPrincipalName)
- CSV (with either no header or a header of UserPrincipalName)
- Target environment type (either Active Directory or Office 365/Azure AD, which return a UserPrincipalName property with Get-ADUser or Get-AzureADUser)
I had gone the “easy” route and just done a simple If/Then to see if the Identity parameter had been passed, and if it had, run a separate chunk of code (which made troubleshooting or updates much harder since I had to keep two branches of the code synced when I made updates).… [ Continue reading ]
Today, while logging into a Windows Server via my favorite RDP tool (RDCMan), I was faced with the “Your password has expired” prompt. No worries, just enter my password and change it.
Except for the part where the password has been saved and I neglected to add it to my password manager.… [ Continue reading ]
My colleague Andreas asked today for some help troubleshooting an issue he’d run into with the Create-LabUsers script failing while using the InflateMailboxes parameter.
The problem ended up being three-fold:
- I had some pre-populated user names that had spaces in them
- I hadn’t trimmed the spaces out when constructing the SMTP address (although I had for the UPN)
- I didn’t test for a valid RFC sender address when constructing the mail
So, all of those things together conspired to generate errors whenever some of those user names were hit. … [ Continue reading ]
Today, I just put together a quick little project for a friend of mine who needed a way to scrape downloadable documents and video files from a website for a project. Rather than clicking and downloading each one manually, he wondered if there was a way he could do it with a script.… [ Continue reading ]
I couldn’t really come up with a cool-sounding title for this post, so I just went with the basics of what it does.
Last week, I worked with a customer that wanted to deploy custom retention labels to custom folders inside a user’s mailbox–the idea being that they would create a custom folder structure such as this under a user’s Inbox:
\Inbox\Retention Schedule\2 Year (apply a 2-year retention label to everything in this folder)
\Inbox\Retention Schedule\4 Year (apply a 4-year retention label to everything in this folder)
\Inbox\Retention Schedule\7 Year (apply a 7-year retention label to everything in this folder)
\Inbox\Retention Schedule\Forever (apply a ‘Never delete’ retention label to everything in this folder)
Seems easy enough, right? … [ Continue reading ]
Here’s a fun one … Disabling Teams auto-startup. Imagine this scenario:
- You haven’t trained your service desk on how to answer/troubleshoot/manage Teams help desk calls
- You’ve configured restrictions on who can create Teams
- You’ve deployed the new Office ProPlus update with Teams integrated.
… [ Continue reading ]
This certainly seems to be a day for updates! Based on some additional feedback from my peers, I’ve updated the Get-UserHoldPolicies script to exclude legacy Exchange MRM policies by default. MRM policies, while they have RetentionPolicyTags, are technically either moving or deleting content, not preserving it.… [ Continue reading ]
Based on some user feedback, I’ve made the following modifications to the OneDrive for Business Admin Tool:
- Fixed a reference to the original function name for FolderToDelete
- Added verbiage referencing the -Confirm parameter when using FolderToDelete parameter
- Tidied up code indentations to make it more readable
I’ve got some additional feedback that I will incorporate as well (once I figure out how to do it).… [ Continue reading ]
As my kids are eager to tell me, I done messed up. 😉 One of my readers pointed out an oversight where a null variable may have been referenced–and it’s been corrected! H/T to @itpro_tipscom!
You can get the updated version at https://gallery.technet.microsoft.com/PwnCheck-HaveIBeenPwned-d65cf5f1.… [ Continue reading ]
Just had this come up, so I thought I’d post it for whoever else needs to hear this. I can quickly think of three ways to do this: One using Outlook, one using PowerShell, and one using both.… [ Continue reading ]
Yesterday, I came across a request for a script or method to download all files from SharePoint Online.
At first, I balked because CSOM isn’t my favorite and kind of finicky, but then remembered that we’d released the SharePoint PnP PowerShell cmdlets a while back.… [ Continue reading ]
An issue came up today for one of my customers–how to remove orphaned mailbox searches in Exchange Online. Apparently, they have about 300 mailboxes in this state. Oops.
So, in order to do this, you need to go through a handful of steps:
- Identify all of the Mailbox Searches.

This week, I had a customer ask about generating a list of all sites a user had access to as part of their security and employee termination process. SharePointPnPPowerShell seemed like a good place to start. But then, I decided, what if I wanted to find all the places a particular had a particular type of permission? … [ Continue reading ]
A few weeks ago, I ran into an issue with a customer. Scenario:
- Customer had configured alternate-id sign in with AAD Connect (the gist is that it flows on-premises mail to cloud UPN)
- Synced identity to tenant
- Tenant did not have any verified domains
As expected, without a matching verified domain in the tenant, UPN suffixes in the tenant were actually set as @tenant.onmicrosoft.com. … [ Continue reading ]
Sometimes, your mind just gets to thinking about stuff you could have done better. Last night was one of those times.
I’d started building new lab environments for work, and decided to start pumping users into AD and syncing them to my test tenants. … [ Continue reading ]
One of my peers this week was looking for a script to help check global DNS resolution for particular records for both replication and geo-loadbalancing testing.
The record types and data he was looking for:
- TXT (for SPF)
- TXT (for DMARC)
This is what I came up with, so maybe it can help someone else.… [ Continue reading ]
Yes, these seems like a silly feature to add (since you can just do a single identity from the haveibeenpwned.com website, buuuuuuuttttttttttt…..), I wanted to showcase the script’s versatility while at a customer, so I added this one on the fly today.… [ Continue reading ]
This is just a quick update–if you’ve been using my Get-UserHoldPolicies script to check out the holds applied to your mailboxes, I’ve updated it to include the DelayHoldApplied property.
A Delay Hold is applied whenever a hold is removed from a mailbox (as in, the mailbox is excluded from an inherited policy or manually removed from an explicitly included policy), and stays in effect for 30 days. … [ Continue reading ]
Right before sending a customer the link for the tool, I decided to test it and noticed that I encountered an unexpected credential prompt. I updated the parameter name, and then added a new feature as well–a test to see if your tenant has the correct licensing to enable Password writeback. … [ Continue reading ]
