Lync 2013 / SfB 2015 Client Security Update – July 2019

Here we are boldly staring down Christmas again for another year, and I’ve just realised not one but TWO updates to the Office 2013-based Skype for Business client have snuck past me in recent months. (Well, at least I have a handy New Year’s Resolution up my sleeve now…)

The previous update was June, and this security update (Kb 4475519) took us from 15.0.5145.1000 to 15.0.5153.1001.

What’s Fixed

“This security update resolves an information disclosure vulnerability that exists if Microsoft Exchange allows entities to be created even though they have Display Names that contain non-printable characters.

Our annual housewarming – the DHMG

Rocky and I bought our first home together back in late 1995. It was a lovely 3-bedroom semi-detached house in one of the inner-western suburbs of Sydney.

We found ourselves holding a housewarming for it in January 1996, and for some reason lost to history we settled on a parody / lampooning of the poster for the annual Sydney Gay & Lesbian Mardi Gras, re-creating the organisation and re-convening its signature event a few suburbs to the west.

Original image credit: artsandculture.google.com. Original poster art: Glenn A Moffat.

Somehow the party became an annual celebration. Certainly the venue lent itself to a late-Summer party, with the airy internals complemented nicely by the small patch of green out the front, and the small backyard.

Adventures with Import- and Update-CsUserData Pt.2

I’ve spent a lot of time this year working with the <verb>-CsUserData commandlets in SfB, and it’s been an interesting time.

This is part 2 in a series where I document the traps I’ve fallen into with the Import-CsUserData and Update-CsUserData commands in particular.

Part 1 – Update-CsUserData fails on bad data.
Part 2 – Your Front-End won’t start after Import-CsUserData imports bad data.
Part 3 – Update-CsUserData throws false red and runs slow if your paired pool is offline.
Part 4 – You can’t trust Import-CsUserData to tell you if it fails.

In Part 1 I showed how Update-CsUserData will throw an error if you try to import “bad data” – and in that example this boiled down to two occurrences of the same “buddy” in a contact file exported from Lync 2010.

What do you think happens if you try to import the same XML/ZIP file using Import-CsUserData? I’m glad you asked.

Part 2 – Your Front-End won’t start after Import-CsUserData imports bad data

TL;DR: It looks like there’s not a lot of validity checking in “Import-CsUserData”. Provided the file is valid XML, the DLL(?) that does the work just copies the Buddy data – as XML – directly into the back-end SQL database. The problems arise later when the Front-End SQL database parses that XML and tries to plug it into its own tables where each Buddy is a Primary Key and MUST be unique. Now you’re in strife.

I believe you’ll only be impacted if your source is formatted as Lync 2010 data.

Get-RibbonSbcUptime.ps1

Inspired by a question from John Cook on Twitter, I’ve taken my “Update-RibbonADCache.ps1” script, and through the magic of “Save As” we now have Get-RibbonSbcUptime.ps1.

Get-RibbonSbcUptime.ps1 invokes a REST login to your Sonus/Ribbon SBC 1k/2k/SWe-Lite and reports how long it’s been running: the CpuUptime.

It outputs to the pipeline either a timespan object, or a literal string in the same format the SBC displays on its System/Overview tab.

Adventures with Import- and Update-CsUserData Pt.1

I’ve spent a lot of time this year working with the <verb>-CsUserData commandlets in SfB, and it’s been an interesting time.

This is part 1 in a series where I document the traps I’ve fallen into with the Import-CsUserData and Update-CsUserData commands in particular.

Part 1 – Update-CsUserData fails on bad data.
Part 2 – Your Front-End won’t start after Import-CsUserData imports bad data.
Part 3 – Update-CsUserData throws false red and runs slow if your paired pool is offline.
Part 4 – You can’t trust Import-CsUserData to tell you if it fails.

Background

My customer is a LARGE deployment, and they’re moving from Lync 2010 in a user forest to SfB 2015 in a resource forest. In an effort to make this transition as seamless as possible for the users, the plan is to migrate all their contacts (their “buddies”) from the existing platform to the new.

The approach we’ve taken breaks the process into multiple steps:

  1. Export-CsUserdata on Lync.
  2. Use a bespoke PowerShell script to break down the single data export (all 10+ Gig of it) into a contact list XML file for each user.
  3. Use Convert-CsUserData and the “-TargetVersion Current” switch to convert each user’s file from Lync’s XML to SfB’s ZIP format.
  4. Sanity-check each user’s file with “Update-CsUserData -TestMode”.
  5. Import the data. We initially chose “Update-CsUserData” and fell into a hole, so we changed to “Import-CsUserData” – and fell into a different one.

This series will document those bugs and hopefully prevent others from earning the same scars.

Cannot Start Microsoft Outlook

I’ve been travelling a lot for work this year, and when I’m away from home I generally leave my home PC on.

It was upon returning from a work trip that I found Windows had pushed an update to it, and it had restarted – and from that moment, Outlook was broken.

Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. The attempt to log on to Microsoft Exchange has failed.

I tried all the usual suspects thinking this was going to be a quick fix:

  1. Repair Office.
  2. Run Outlook in Safe mode. (Start / Run / outlook.exe /safemode).
  3. Reset the nav pane (Start / Run / outlook.exe /resetnavpane).
  4. Create a new profile. (Start / Control Panel / Mail / Show Profiles / Add…)
  5. Ran the “Outlook Support & Recovery Assistant“.

No dice.

Microsoft Teams Deep-Dive – Canberra follow-up

I presented a Teams Deep-Dive session at Microsoft’s office in Canberra this week.

At the end there were a few links I wanted to share with the participants, and a few homework questions I wanted to research and respond to. A blog post seemed the obvious way to provide them with that info.

The below will be of greatest relevance to the attendees, but even if you weren’t there I think you’ll find some bits of interest.
