Flashback to what it took to do math in DOS batch files

While working on a script for an upcoming project, I wanted to test for the presence of various Office versions, including 32-bit and 64-bit components before initiating setup. Here’s one way I found:

SET CURRLOCATION32="C:\Program Files (x86)\MicrosoftOffice\root\Office16"
SET CURRLOCATION64="C:\Program Files\MicrosoftOffice\root\Office16"
SET PREV1LOCATION32="C:\Program Files (x86)\MicrosoftOffice\root\Office15"
SET PREV1LOCATION64="C:\Program Files\MicrosoftOffice\root\Office15"
SET PREV2LOCATION32="C:\Program Files (x86)\MicrosoftOffice\root\Office14"
SET PREV2LOCATION64="C:\Program Files\MicrosoftOffice\root\Office14"

Export Credential Manager to PowerShell

If you ever find yourself in a sticky wicket and need to extract usernames and passwords from Credential Manager (usually because you forgot them), you can use this handy-dandy little function from PowerShell:

function ExportCredMan
    # Dump local passwords from credential manager

Creating an Array with Headers and Columns from a string using [PSCustomObject]

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 ]


Update to Create-LabUsers Script

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 ]


Apply Security & Compliance Center Retention Labels to Outlook Folders

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
\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 ]
