When there was a name change in Active Directory (AD), we used to update the Universal Principal Name (UPN) in AD, then separately run the Set-MsolUserPrincipalName command to update Azure AD to the same UPN. Except, it no longer worked – I was now getting an ‘Access Denied’ message.
When trying to update the UPN via the Microsoft 365 admin center, it would correctly advise that the object was homed in AD, so changes needed to be made there. Except, they were, and Azure AD Connect was even reporting that it had seen the update and sent it off to Azure AD, no errors.
After some investigation, I found that there is now an option to allow ‘Synchronize userPrincipalName updates‘ which is off in older tenants. To check and update this:
In PowerShell, first install and connect to MSOLService. Then to check the status if UPN updates will sync and update:
In my testing, running another Azure AD Sync (both delta and full) did not resolve any already updated UPNs. I had to change the UPNs to a temporary value, sync, then change them back to the original value I wanted, and sync again. The update was instant in Azure AD once the sync had run each time.
Poly kindly sent me a new piece of hardware to review – the Poly Studio P15. It’s on of the devices in their ‘Poly Studio P Series‘ which only came out early in 2021. These devices are personal video devices, but aimed at the higher end of the market. It includes the Poly Studio P5 Webcam (or kits that include the webcam and a headset or speaker), the Poly Studio P21 Personal Meeting Display, and this Poly Studio P15.
Although you could call the Poly Studio P15 a webcam, Poly calls it a Video Bar. Which I think is fair enough – it’s 42.5cm long (17 inches). On a standard 24″ monitor it extends above a lot of the screen, but luckily on my 43″ it is quite a good fit. The mechanism that balances the device on top of the monitor is quite adaptable – with both an adjustable kicker, as well as being able to slide the base forward or backward means that I could get it quite stable, without getting in the way of my actual display area.
Out of the box, beyond the video bar and kickstand, is a USB-C cable, and a power pack. The lens itself can be rotated to open/close the lens cap. Once plugged in to power and the compuer via USB-C, that’s all that’s needed for the camera to show up in Windows 10; no extra software is required to make it function, but if you want to change settings or run updates, you’ll need the Poly Lens app.
The Poly Studio P15 specifications are below.

Due to the camera’s 4K resolution, it can use digital zoom to still produce a high quality 1080p result. Below I’ve taken a screenshot of the auto-framing to my face, vs turning the tracking mode off to show the full field of view the camera can pick up. Again, this works out of the box without the app which is nice.
To be able to change these settings however, you’ll need the Poly Lens app, which is a free download. It doesn’t need you to sign in, but will provide firmware updates to your Poly devices, along with configuration options around back light compensation, zoom, camera movement, tracking speed and frame size. These settings let you fine tune how the video bar acts with it’s automatic controls.
Other settings worth noting are the Poly Acoustic Fence which creates a virtual bubble around the device, and sounds outside the bubble aren’t heard. I’ve liked a Poly video below around this. There’s also the NoiseBlockAI option which block sounds like typing – which I can confirm nobody could hear me typing on my mechanical keyboard while on an audio call, which was nice rather than wearing a headset for once.
The audio quality that comes out of the video bar I thought was really clear – you can also adjust the bass and treble levels to your liking.
One little bonus I saw in the Poly Lens app was the Soundscaping option – if you want the background noises of the gentle ocean, a babbling brook or a mountain ranch (which sadly isn’t cowboys and cowgirls saying ‘howdy partner!’ with horses neighing, just more water running):
Anyway, the Poly Studio P15 is really a high end device for the home professional that doesn’t want to muck around with trying to get the right angles, or worrying about being out of shot. The videobar sorts all this out for you, while being configurable enough to give some controls around those smarts. It also doubles up as just a really good speaker, and for an environment particularly at home where you might have outside noises or unwanted visitors, turning on the Poly Acoustic Fence can save the people you’re talking to from interruptions and distractions. There’s also two USB 2.0 ports on the back, in case you have other devices to plug in like headset USB dongles.
A really cool solution with some extra bells and whistles to justify upgrading from an average webcam.
SMTP is still needed by certain applications and devices, such as printers, which don’t support Modern Authentication and instead require legacy authentication to talk to a SMTP server.
You are able to use Exchange Online as an SMTP server, but this can be tricky to set up if you’ve hardened your environment by requiring Multi-factor authentication through Security Defaults or Conditional Access.
Assuming you can get out through your firewalls on port 587 or 25 for SMTP, you’ll need to turn off Azure AD Security Defaults if you have them on. If you do this, understand what you’re turning off and rebuild those same settings in Conditional Access. If you have them off, then you should have Conditional Access policies already.
Personally, I have a ‘Block Legacy Authentication’ conditional access policy which as it says, blocks legacy authentication. For an account I want to send emails from via SMTP, I add it as an exception to this policy.
I then have a second policy ‘Allow Legacy Authentication Internal Only’ which I then target this user at, which still blocks legacy auth unless it’s coming from a trusted IP address. These two rules together then block all users from legacy auth, except the ones on the second policy, and then only if they’re coming from inside my network. The goal of this is to prevent anyone externally using spray attacks against accounts to gain a username and password – although they couldn’t log in anywhere beyond SMTP due to MFA policies, they could still start sending emails that would be from a legitimate email address.
If you have IPs restricted on Exchange Online connectors, that does not appear to affect SMTP auth and you shouldn’t need to add your internal IPs there.
The account you want to use for SMTP sending must have a mailbox license, I use ‘Exchange Online Plan 1’ for one of the cheaper options that is pure mailbox. The SMTP settings are listed here.
You also need to allow SMTP auth across your organisation (not ideal), or on a per account basis (much better security wise, plus it overrides the org default – so you can disable at org level and allow at account level). Microsoft Docs covers this in detail but the command (which requires connecting to Exchange Online via PowerShell first) to allow on a single mailbox is:
Once these policies and licenses is in place, you can test. The easiest way I found was a 1 liner PowerShell command. You must use the source mailbox’s account as the from address:
Send-MailMessage –From [email protected] –To [email protected] –Subject "Test Email" –Body "Test SMTP Service from Powershell on Port 587" -SmtpServer smtp.office365.com -UseSsl -Port 587 -credential $madeupvariable
When testing, I found that after changing the Conditional Access rules to let a specific account go through as legacy auth took several minutes. Azure AD logs also take several minutes to show auth attempts, so don’t rush and change too many things at once trying to do this.
Ideally, nobody would be using SMTP – but in the real world we still have to, so the above will at least keep login records in Azure AD, and limit it to trusted IPs, certain accounts, or any other Conditional Access rules you can come up with to reduce the risk of allowing this.
I had this problem on a server for a while – when first launching PowerShell, it would take ~20 seconds or so to accept input. Also, when pressing tab to auto-complete a command, it would again take ~20 seconds to start, like it was freezing. These were one time problems when launching PowerShell, after that it would work fine until a new session was launched.
A lot of searching didn’t help me work it out, so I logged a Microsoft case. After a few task manager executable dumps, they worked out the delay was on a path I had in an environment variable. Somehow in my account’s user variable, I had a github desktop path that was mapping to a network share, using a PC name that was decommissioned (e.g. ;\\pcname\c$\Users\AdamFowler\AppData\Local\GitHubDesktop\bin.
I expect that this name was timing out, and PowerShell was waiting a while before giving up. In case you have the same symptoms as me, check the environment variables – user variables paths if it’s only your account affected, or the system variables if it’s all users. Click on the path value, then click edit, and remove anything that shoudn’t be there (take a backup of the text if you aren’t sure, it’s easy to put back in if you keep a copy).
To get to Environment Variables, depending on the OS version, get to System Properties, the Advanced tab, and then the Environment Variables button:
Hope that helps someone else with the same problem!
Device limit reached – You have added the maximum number of devices allowed by your company support. Plesae remove a device from the Azure portal or get help from your company support.
There’s a limit to the amount of devices you can register for the Intune Company Portal app.
To fix this, yes you’ll need to remove a device attached to your account. This is not done via Outlook for Web, where you can remove devices – that’s purely for Outlook. It’s also not done via https://myaccount.microsoft.com/device-list as it’s not removing it from Azure.
As per Microsoft Documentation , there’s Intune device limits, and Azure device limits. Intune / EndPoint Manager has a maximum of 15 devices, where Azure has a default of 20, but can be changed to a few different values, including ‘unlimited’.
Intune / Endpoint Manager Device Limits
Azure Device Limits
To remove devices from a user, and admin should use Azure Active Directory and go to Users > Find the user > then under Manage, choose ‘Devices’. Any old device (check by the activity date) can be selected and deleted.
After removing enough devices here, you should be able to register the new device via the Intune Company Portal app again – and in my testing, this was next to instant.
