Introduction Recently, I’ve been wanting to use PowerShell Core more often with Graph API. But what has held me back was having to use WinForms or WPF to display the Microsoft login page to authenticate the user. Searching around, it appears you can authenticate Azure AD users with a device code too - https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-device-code By doing this, your script/tool/app/device can generate a device code to be entered on another device (that has a web-browser). For example, I can run a PowerShell Core script on a headless Ubuntu server which provides a code, then use that code to sign in from my Windows PC. ...

Introduction I’ve been asked a few times if there is an easy way to report on all web pages in use within Teams. The two main reasons are: Intrigue in to what sort of web pages users are attaching to their Teams A way of policing users to ensure the feature is not being abused (perhaps a website is blocked using a web-browser but works via Teams) Pre-requisites As with a lot of my posts, out comes PowerShell and Graph API. At this point, I will have assumed you have: ...

Introduction Backup-TeamsConfig is a PowerShell script allowing you to backup various parts of Microsoft Teams configuration and package it up in to a single file for safe keeping - this includes policies, configurations and voice applications (inc. audio files). Why? - Doesn’t Microsoft already keep copies of this? I’m sure they do. However it doesn’t hurt to have a copy should the unthinkable happen! ...

I’ve previously blogged about the Office 365 Service Communications API before and how it can be used to obtain the service status/health of services in your Office 365 tenant. The API also allows you to get historical status along with messages (from message centre, incidents etc.). In my previous post I showed how this could be done in Flow using a standard HTTP call within each Flow. It works, but it also means you need to set up authentication and each API call manually (even if in the same Flow). ...

When first using Graph API a feature I missed was that data was paged. For example, if I want to retrieve all the groups in a tenant, I would use the following endpoint: HTTP GET: https://graph.microsoft.com/v1.0/groups This worked fine for me in the demo tenants I was using – I would get all the groups back. However, I found out there is a limit to results returned (for groups it is 100)! This is down to paging (see explanation here). ...

One project I have been working on recently at Symity is a global roll out of Teams Direct Routing. This has resulted in SBCs being installed in different configurations based on local connectivity and requirements. One such requirement is where sites have multiple internet connections for resilience - can the SBC make use of this? It makes perfect sense especially when using cloud-based service – if one ISP has an issue, you want to be able maintain service with the other. ...

Microsoft have recently announced that they will be retiring Skype for Business Online on 31st July 2021. After this time, you will no longer be able to access Skype for Business Online. If you’ve been paying attention this isn’t a massive surprise. Teams is the new-ish kid on the block, getting all the attention and had been earmarked as Microsoft’s communication and collaboration tool moving forwards. Once ‘feature-parity’ was announced, Skype for Business Online’s days were numbered. ...

Last Updated: 2nd October 2019 Introduction This article will give an explanation of the Teams Call Queues (CQ) and Auto Attendants (AA) - what they are and how to set them up. You could previously create and administer the “SfB” CQ and AA in the (legacy) Skype for Business Admin Centre, but these have now been migrated as “Teams” CQ and AA in to the Teams Admin Centre. There are some key differences between the two versions that I will highlight: ...

Introduction You may from time to time have run in to an issue where an Teams/SfB user has not been provisioned correctly. The most common scenario for this is a delay in Office 365 provisioning the user - you have assigned the required SfB/Teams licenses and it has yet to become available to the end user (it is not uncommon for licenses to take over 24 hours to be provisioned). ...

This article will assume you already have Teams Direct Routing in place. If you are not there yet, consider looking at my article on this subject: https://www.lee-ford.co.uk/teams-direct-routing-with-an-audiocodes-sbc/ Introduction to Media Bypass A welcome addition to Teams Direct Routing is Media Bypass. Before Media Bypass was released, all media when using Direct Routing would need to route up to one of six regional Teams Media Processors and back even if the Teams client and SBC were in the same location. Whilst this does work, it can be sub-optimal. If you then add on the fact that Media Processors are only available in six datacentres worldwide, it can add up to some large round trip times dependent on your location. ...
