  1. Microsoft Teams starts but user cannot log in: a problem has occurred


    We use Microsoft Teams in our organization. A user has encountered a problem with Teams since a few days. Every morning when she arrives at work and boots her laptop, Teams starts but states a problem has occurred. Restarting Teams doesn't work, logging off and on again (in either Teams or Windows) doesn't work either. The errorcode shown on the screen is caa5004b. I've updated Teams to the latest version (1.4.00.8872) but this didn't help. Online I've found a list of directories to clear in order to clear the Teams cache, but that didn't work either. In the end I ended removing Teams, removing ALL Teams directories under her appdata folder, and reinstalling Teams. This fixed the issue, and she was able to use Teams again for the entire day. Unfortunately, the next day she was faced with the exact same issue. I reran the steps above, and the issue was fixed again. Today I had to do this for the third time, so I'm looking for a more permanent fix Microsoft Teams starts but user cannot log in: a problem has occurred :) The bizarre thing is that if she reboots her laptop during the day, or turns it off/on, Teams happily continues to work. It's only when she boots her laptop first thing in the morning that Teams won't work. We have numerous PCs and laptops, all running Windows 10 with the same or near same versions of Teams, and this is the first time I've encountered this behaviour... I'm really puzzled why this happens, and I was wondering if anyone could point me in the direction of a fix. Thanks!

    :)

    Edge Search Does Not Permit Change of Region


    I got these suggestions from the Microsoft Community forum.No. 1 worked for me:

    Thank you for posting the query on Microsoft Community. I am glad to assist you on this.
    We have reproduce the issue here and we are able to access non-regional search for google using Microsoft Edge.
    I would suggest you to try the below steps and check if it helps.
    Step 1:
    Clear browsing data option of Microsoft Edge and check if you face the issue. To do so perform the steps below.

    1. Click on the More actions icon next to the feedback icon present on top right corner of the Project Spartan homepage.
    2. Select Settings and click on Choose what to clear.
    3. Check the boxes Browsing history, Cookies and saved website data and Cached data and files and click on Clear.
    Step 2:
    I suggest you to create a new user account and check if the issue occurs.

    1. Go to Settings.
    2. Choose Accounts and then select Family and other users.
    3. Select add someone else on this PC.
    4. Enter a user name and hit next.
    5. Click on Finish.
    6. Sign out from the current Account and Log into the new account.
    Step 3:
    It could also happen because of network issue. I suggest you to try with different network connection and check if it helps.
