Using Bot app in different organization
Hello,
I have created a bot app using teams toolkit and run it locally. Using the teams toolkit, it has automatically created a app in developer portal of teams, created a app in app registrations in azure and a bot in botframework. The app in app registration in azure is supporting Multiple organizations. Now using this I have hosted the bot on server of which endpoint I have also mentioned. So the app is running in my tenant. Suppose I want my client which is other organization to install and use this bot without publishing into the marketplace. How and what to configure to use them. Or the user can have just upload the manifest file and use it even though it is registered in my tenant?
Thanks.

How to manage FileVault personal recovery keys with Intune on previously encrypted MacOS devices
With the rapidly evolving digital landscape, organizations are increasingly turning to Microsoft Intune as their preferred MDM (Mobile Device Management) provider and working on migrating devices from existing MDM solutions to Microsoft Intune.
Migrating device management from one MDM Provider to Microsoft Intune requires several configurations – more details can be found in this article. In this blog, we are going to take a closer look at MacOS device migration from JAMF to Intune, with focus on FileVault key escrow feature.
Migrating MacOS devices from JAMF to Intune involves several steps to ensure smooth transition of the device to Intune and minimizing the impact of productivity. During this process, one of the biggest challenges is getting FileVault recovery keys escrowed back to Intune. We will be focusing on steps which we took to escrow the personal FileVault recovery key to Intune. The specifics of your migration may vary depending on your organization’s requirements and the complexity of your existing setup. It is recommended to thoroughly plan and test each step to minimize disruption during the migration process.
There are two main scenarios in which the FileVault key storage process can be categorized:
Device was not FileVault enabled before Intune enrollment (FileVault enabled via Intune policy after enrollment)
Devices marked as “Personal”: Recovery key can only be seen by the user via the Company Portal Website
Devices marked as “Corporate”: Recovery key can be seen by IT (information technology) administrators in addition to owner of the device
Device was FileVault enabled before Intune enrollment:
In this case, the FileVault recovery key is not managed, and Intune is unable to escrow. It is most likely that the recovery key was stored in iCloud.
From this point on, we will be focusing on the 2nd scenario.
The following error message will be shown for the FileVault setting in Intune policy reporting, if FileVault was enabled before Intune enrollment. Intune requires FileVault ownership to apply the “Enable FileVault” setting successfully:
There are multiple ways in which FileVault management can be assumed by Intune. In our implementation, we chose options 2 and 3 from below because they do not require decryption and re-encryption of the drives. Re-encryption adds additional complexity as it will expose user data during this process and consume more time to complete migration. Also, regardless of the option, the steps outlined must be executed by the user who initially enabled FileVault:
From MacOS GUI (graphical user interfaces): From GUI, there is no option to just refresh the recovery key, so it is required to decrypt the device and re-encrypt the device.
On the device, choose Apple menu > System Settings, click Privacy & Security in the sidebar, then click FileVault on the right. (You may need to scroll down.)
Turn off FileVault and turn it back on
Device sync
Terminal commands to refresh the recovery key
Users need to launch the Terminal app on the device.
Run “sudo fdesetup changerecovery -personal”
You will be prompted to enter device admin credentials.
IT Admin generated script/app: Sample scripts can be found at below locations, and these scripts can be customized and deployed as an app.
https://github.com/jamf/FileVault2_Scripts/blob/master/reissueKey.sh
or
Deploy FileVault key refresh script as Application from JAMF
Unenroll the device from JAMF
Enroll device to Intune
Deploy FileVault policy from Intune
Run the key refresh script (which deployed previously) from application applet
Once the user executes the application, the device generates a new personal recovery key, Intune assumes management of FileVault encryption on next Intune check-in, and users can see the recovery key in the Company Portal website.

Simulink Discrete Filter Sample Time
Hello everybody I’m new here and new to simulink.
I have a problem
The Sample Time was "canceld" for the discrete Filter in the update 2023b.
At least the easy Set Up trough the Block Parameter, but I need it to initiated for the Task In Simu Link Fundamentals at step 4.5.
Does anyone know what i can do know? that would made my day.
Thank you
Best Regards

Ellipsoid Mask based on user input of dimension and euler angle
Actually I am trying to generate a 3d ellipsoid mask based on the user input of semi axes and euler angles. But in my code to do this I am calculating the distance of each pixel from the centre of the ellipse and then based on the ellipse equation pixels falling inside this ellipse are assigned true values. But the problem is that this operation is very tedious as I am scanning each and every pixel.
Any other way to do this which reduces the time complexity of this problem.

Workaround to avoid duplicate content marking when using a third-party signature tool?
Hi team,
Been hitting my head against a wall trying to deal with Microsoft support, so I’m hoping someone here may be able to assist me more effectively!
We are adding content marking to emails when certain sensitivity labels are applied, e.g. ‘Internal’. We’ve also started trialing a third-party signature tool (Exclaimer) to apply server-side and client-side signatures to outgoing mail.
Unfortunately, since implementing Exclaimer signatures, duplicate content marking is being applied to the emails. Based on the below thread and comment by ratzq, this has been previously logged with Microsoft and they advised it’s a bug.
I’m wondering whether anyone has successfully implemented a workaround to avoid this problem, or can confirm whether there is still no known solution.
After spending several hours on calls with Microsoft support then being told the “behaviour is expected”, I’m not optimistic. I also raised a ticket with Exclaimer, but they weren’t able to help – and since it’s the content marking which is appearing twice, as opposed to the signature, I don’t believe it’s anything they can affect.
Thanks!
