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
\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 ]

Exchange Online Protection (EOP) Best Practices and Recommendations

Yes. I said it.

Someone needed to put a line in the sand and today, that person is me.  I’m going to say these are some best practices.

But of course, your mileage may vary, depending on your type of organization (users at a local bank or city government will have different threats presented to them than an engineering firm with international customers, for example). … [ Continue reading ]

Update to Get-UserHoldPolicies

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 ]

Update to OneDrive for Business Admin tool

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 ]

Cloud UPNs for AAD Connect users with Alt-ID don’t update after domain verified in tenant

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 ]

Update to Create-LabUsers!

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 ]

Update to Get-UserHoldPolicies — Now includes DelayHoldApplied

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 ]
