Mailbox Delivery Settings

From time to time, I run into environments where things are configured in “non-standard” ways.  Granted, we don’t have a lot of specificity or documentation around some attribute configurations because the default configuration has been tested by the people who created the software and works in almost every conceivable situation. … [ Continue reading ]

PowerShell Random Password Generator

On a project earlier this year, I had to create random passwords for user accounts as part of a provisioning tool.  Perpetually trying to find the fastest way to do something, I came up with a one-liner that you can use to create a random text string from the following ASCII printable characters:

A few weeks ago, I had an issue where I needed to remove a proxy address from the proxyAddresses array of a user being synchronized to Office 365. … [ Continue reading ]

Testing for bad SMTP Addresses

While working on my latest project,  I encountered a significant number of objects with malformed SMTP addresses.  These appeared to have been objects that had been somehow manually modified over the years by directly writing to the proxyAddresses attribute in Active Directory, bypassing an API that would check for correctly-formatted addresses.… [ Continue reading ]
