Microsoft Teams is one of those apps that everyone loves to hate. There are many reasons why people don’t like it. Some say it doesn’t work well enough while others complain about how slow it is. But what do we really know about it? We’ve asked around and found out some interesting things about the app. Here are 3 things we learned about Microsoft Teams.

You can use both Skype for business and Microsoft Teams in one Company

If you’re looking for something that works across both Skype for Business and Office 365, Microsoft Teams might be a good option for you. While there aren’t too many features that cross over between the two products, Microsoft Teams does offer a lot of functionality. For example, you can use it to collaborate with co-workers, hold meetings and even host webinars.

Microsoft Teams is a great option for smaller companies

For small businesses, Microsoft Teams offers a great solution because it allows employees to communicate effectively without needing to pay for expensive enterprise plans. Plus, it’s free. However, if you’re planning on growing your team quickly, you’ll probably want to look at another product.

Microsoft Teams has been around long enough to get its bugs fixed

There are a number of bugs that affect Microsoft Teams, but it seems like the biggest issue is related to the fact that it isn’t updated very often. When we tested it recently, we noticed that the app wasn’t working properly on Windows 10 devices. This caused problems such as messages being sent to the wrong recipients and missing images. We also found a particular issue, the error code caa50021 – This error occurs in any office 365 pro desktop app while configuring outlook and ms team.

Microsoft Teams is one of those applications that you just don’t want to update because it breaks things. You know what I mean – there are always some problems after updating. But, Microsoft does provide a way to roll back to the previous version, so we’ll show you how to do that.

Get in touch with your IT admin for assistance

Microsoft 365 subscriptions are great because you don’t have to worry about installing software, updating patches, or managing servers. However, sometimes things go wrong. If you’re having trouble accessing your account or receiving messages from Microsoft, contact your IT administrator immediately. They’ll know how to help resolve the issue.

Register the Device With Azure AD

Azure Active Directory (AD), Microsoft’s identity management solution, allows you to register devices such as smartphones, tablets, PCs, etc. This feature enables organizations to manage and control device usage. If an organization uses Azure AD for authentication, it must ensure that the device used for login is registered with Azure AD.

If the device is already registered with Azure AD, follow the steps mentioned here to unregister the device.

NOTE: You cannot unregister a device if it is still being used. To prevent this scenario, make sure to deactivate the device before unregistering it.

1. Open the portal.azure.com URL in your browser.
2. Click on the Settings icon located on the left side menu bar.
3. Enter the email address associated with the device.
4. Select Unregister.
5. Confirm the removal request by clicking OK.
6. Wait for the confirmation message to appear.
7. Once the device has been successfully removed, click Close.
8. Log out of the portal.

Remove Microsoft Teams credentials from your account

Update Teams to the latest version. Disable background processes, including your antivirus. If you are running Office 365 ProPlus, you can disable the following processes:

• Open the Windows Credential Manager and delete all the credentials in the list with “Teams” in their name. This includes your Microsoft account, Outlook.com email address, Skype ID, etc.
• If you use multiple devices, make sure to check each device separately.
• You might want to keep some credentials around just in case something goes wrong. But we recommend deleting everything.
