There are a lot of bugs, which I don't know how many people have come across.
In Microsoft Teams, when you share any screen, I can't see much because the Microsoft Teams Window takes the majority of the space. A task section comes up and then below the screen, a list with the names of the people you are collaborating with comes up. When you have to share the screen, you get a small window, which also depends on the screen resolution of the person seeing it and sharing it. You basically need to have an extendable monitor and display unit to see the bigger screen. There should be a full functionality for changing the desktop screen to full screen. That would really be fantastic. This is surely going to be a critical area. If you see Zoom and Cisco WebEx, you get the full wider screen.
In Microsoft Teams, voice quality can be made much better. I think the codex part can be something on which they can work further.
In Microsoft Outlook, the GUI is years old, which is boring and makes you want to switch to the postal way of sending emails. They must change the GUI.
I am a bit skeptical about the promises that are made by Microsoft. Even though Microsoft makes promises that your data will reside on the servers within your country. I don't think it is so, and the corporate data, the governmental data, and the patient data are still in Europe. In terms of the land laws, even if I have an agreement with Microsoft that my data should not be shared with any other countries, at the end of the day, the data is residing on some other land. So, the land laws of that particular country have the right to have access to the data that is residing on the server of a particular continent. So, the government can intercept the data. That's why I'm a bit skeptical. However, so far, no cases have come up related to this, but one day, it may come up. I hope Microsoft will find out a permanent solution for that. People are becoming more aware of privacy.
