External Sharing in Microsoft Teams: Understanding the Rules and Exceptions

As an administrator, managing external sharing in Microsoft Teams can be a daunting task, especially when it comes to understanding the rules and exceptions. In this blog post, we’ll delve into the details of external sharing, explore the different scenarios, and provide insights into how it all works.

New and Existing Guests

Let’s start with the basics. When you set your tenant to “New and existing guests” in the External Sharing settings in the SharePoint Admin Center, you’re allowing external users to access and edit files shared with them. But what about unknown external users? Can they still access and edit files? The answer is yes, but with some caveats.

Unknown External Users

When you share a file with an unknown external user, they won’t be able to download the file directly from Teams. However, if they have a Microsoft account and are signed in to the same Azure Active Directory (AAD) as your tenant, they can access and edit the shared file. This is because the file is stored in SharePoint Online, which uses AAD for authentication and authorization.

Guest Users

Now, let’s talk about Guest Users. When you share a file with a Guest User, they can access and edit the file, but they won’t be able to download it directly from Teams. However, if they have a Microsoft account and are signed in to the same AAD as your tenant, they can access and edit the shared file.

Exceptions to the Rules

There are some exceptions to the rules we’ve discussed so far. For instance, if you share a file with an external user who is not signed in to AAD, they won’t be able to access or edit the file, even if they have a Microsoft account. Additionally, if you share a file with an external user who is not a Guest User, they won’t be able to access or edit the file, period.

How it All Works

Now that we’ve covered the different scenarios and exceptions, let’s take a step back and look at how everything works together. When you share a file in Teams, it’s stored in SharePoint Online, which uses AAD for authentication and authorization. This means that only users who are signed in to AAD can access and edit the shared file.

If an external user is not signed in to AAD, they won’t be able to access or edit the shared file, even if they have a Microsoft account. However, if they are signed in to AAD and have been granted permission to access the file, they can view and edit the file.

Conclusion

Managing external sharing in Microsoft Teams can be complex, especially when it comes to understanding the rules and exceptions. By understanding how SharePoint Online and AAD work together, you can better manage external sharing and ensure that your files are secure and only accessible by authorized users.

Remember, when sharing files with external users, always consider the following:

1. Only share files with users who need access to them.

2. Use the correct permissions to control access to shared files.

3. Be aware of the exceptions to the rules we’ve discussed in this post.

By following these best practices and understanding how external sharing works, you can ensure that your files are secure and only accessible by authorized users.

SpaceX’s Successful Streak Comes to an End: Falcon 9 Experiences Anomaly During Launch

On Thursday, SpaceX’s successful streak of launches came to an end when a Falcon 9 rocket experienced an anomaly during its flight. The rocket was carrying 20 satellites for the Starlink network and had successfully launched from Vandenberg Space Force Base in California. However, during the second stage of the launch, ice formation was observed on the engine, which led to a “rapid unscheduled disassembly” (RUD), as confirmed by SpaceX CEO Elon Musk.

The anomaly occurred around 4:40 minutes after lift-off, when the second stage of the rocket was supposed to ignite and propel the satellites into orbit. However, instead of the expected ignition, ice formation was observed on the engine, which caused it to shut down prematurely. The exact cause of the anomaly is not yet clear, but it is believed to be related to a leak in the oxygen tank.

The Starlink satellites, which were intended to provide internet access to remote areas, are now expected to enter a controlled descent and burn up in the atmosphere. This will prevent any potential hazards from the failed launch, such as debris falling to Earth. However, the incident is a significant setback for SpaceX, which has had an impressive track record of successful launches over the past year.

The incident also raises questions about the future of SpaceX’s launch schedule, as the Falcon 9 rocket is currently grounded pending further investigation. The US Federal Aviation Administration (FAA) has announced that it will be investigating the incident, which could potentially lead to a prolonged grounding of the rocket.

SpaceX’s recent successes have made it a dominant player in the private space industry, with numerous satellite companies relying on its launch services. The failure of the Falcon 9 rocket is a significant blow to the company’s reputation and could potentially affect its future launch plans. However, SpaceX has a history of overcoming setbacks and is likely to continue pushing the boundaries of private space exploration.

In conclusion, SpaceX’s recent launch failure is a significant setback for the company, but it is unlikely to slow down its momentum in the private space industry. With a strong track record of successful launches and a commitment to innovation, SpaceX will likely continue to be a dominant player in the space industry for years to come.

Enabling VMware Fault Tolerance in a Nested Environment

As a VMware enthusiast, I was eager to explore the capabilities of VMware Fault Tolerance (FT) in a nested environment. While it is not officially supported by VMware, I was determined to find a way to enable it for my lab virtual machines. In this blog post, I will share my experience and the steps I took to configure FT in a nested environment.

Background Information

FT is a feature that provides zero-downtime maintenance and failover for virtual machines (VMs) running on VMware vSphere. It uses a combination of hardware and software techniques to ensure that the VM remains available even in the event of a hardware failure. However, FT is not supported in nested environments, as HW virtualization features are required.

My Lab Setup

I use a HP ProLiant DL160 G6 server with two Intel Xeon E5520 processors, 32GB of RAM, and a RAID 0 configuration with four SATA drives. I have installed vSphere 5.5 in my lab, and I am using a nested environment to run ESXi inside my host machine.

Configuring FT

To configure FT for a VM, you need to set three configuration parameters:

1. Edit Settings… > VM Options > Advanced > Edit Configuration…

2. AllowFT = true

3. Replay.allowBTOnly = true

Once you have set these parameters, you can enable FT and start the VM. However, please note that you can only run 32-bit guests, as FT is not supported for 64-bit guests due to binary translation issues.

Screenshots from vSphere Web Client

I have taken screenshots of the configuration parameters and the enabled state of FT in my lab environment using the vSphere 5.5 web client. As you can see, I have enabled FT for a 32-bit Windows 2003 VM, which is sufficient for demonstrating the configuration and use of FT in a lab environment.

Challenges and Limitations

While it is possible to enable FT in a nested environment, there are some challenges and limitations to keep in mind:

1. Limited support: FT is not officially supported in nested environments, so you may encounter issues or limitations that are not addressed by VMware.

2. Binary translation: As mentioned earlier, FT is not supported for 64-bit guests due to binary translation issues. This means that you can only run 32-bit guests with FT enabled.

3. vHV requirement: To use FT in a nested environment, you need to have vHV (Virtual Hardware Virtualization) enabled in the CPU section of your host machine.

4. Limited compatibility: Not all VMs may be compatible with FT in a nested environment. You may encounter issues with certain VMs or applications that are not designed to work with FT.

Conclusion

In this blog post, I have shared my experience with enabling VMware Fault Tolerance in a nested environment. While it is not officially supported by VMware, it is possible to configure FT for 32-bit guests in a lab environment. However, there are limitations and challenges to keep in mind, such as binary translation issues and limited compatibility with certain VMs or applications.

As a spreadsheet enthusiast, I am always on the lookout for new and innovative ways to use this powerful tool. Recently, I stumbled upon a fascinating question in the Excel forum that caught my attention. The user, keltzjd, was looking for a formula that would find a matching value in one column and return a corresponding record from another column.

The user provided an example of two columns, E and F, with values like this:

E6 = “SPA”

F6 = “3.23”

E13 = “SPA”

F13 = “3.23”

The user wanted a formula that would go into cell F13 and return the value “3.23”.

At first, I thought this was a straightforward task that could be accomplished with a simple VLOOKUP formula. However, upon further investigation, I realized that there was more to it than meets the eye. The user wanted a formula that would work for any column and any row, without having to hardcode the column letters or row numbers.

After some experimentation, I discovered that the INDEX-MATCH function could be used to achieve this goal. Here’s the formula I came up with:

=INDEX(F:F, MATCH(E13, E:E, 0))

Let me break down how this formula works:

* E13 is the cell we want to look up in column E.

* E:E is the range of cells in column E that we want to search through.

* MATCH(E13, E:E, 0) returns the relative position of the value in E13 within the range of cells in E:E. In other words, it tells us which row number in column E contains the value we’re looking for.

* F:F is the range of cells in column F that we want to return the corresponding value from.

* INDEX(F:F, …) returns the value at the specified row and column position within the range of cells in F:F. In this case, we use the row number returned by MATCH to retrieve the corresponding value from column F.

With this formula, we can enter any value in column E, and it will return the corresponding value from column F. This is a powerful tool that can be used for a variety of purposes, such as data validation, content scraping, or even creating dynamic charts and graphs.

I was so impressed with this discovery that I decided to test it further by adding more columns and rows to the example. Sure enough, the formula worked flawlessly every time!

To illustrate this point, let me show you an example of how this formula could be used in a more complex scenario. Suppose we have three columns, A, B, and C, with the following values:

A6 = “John”

B6 = “25”

C6 = “New York”

And we want to find the corresponding value in column C for any given value in column A. Here’s how we could use the INDEX-MATCH formula to achieve this:

=INDEX(C:C, MATCH(A6, A:A, 0))

In this case, A6 is the cell we want to look up in column A, and C:C is the range of cells in column C that we want to return the corresponding value from. The MATCH function will return the relative position of the value in A6 within the range of cells in A:A, and the INDEX function will use this row number to retrieve the corresponding value from column C.

I hope this example has demonstrated the versatility and power of the INDEX-MATCH formula in Excel. With this tool at your disposal, you can perform a wide range of tasks that would otherwise be difficult or impossible to achieve with a simple VLOOKUP formula. So next time you’re working with data in Excel, don’t forget to reach for this powerful and flexible formula!
