You will see the error as follows:

Kindly email 365@trinitycollege.lk with screenshot of your error along with the student admission number.



Microsoft Teams may sometimes fail to launch with error code caa82ee2. Usually, the app freezes for a few seconds shortly before this error code appears on the screen. And the error message reads as follows:

We’re sorry—we’ve run into an issue. Restart. If that doesn’t work, try signing out and back in. Error code – caa82ee2.

In this scenario, please try clearing the Teams cache using the steps below to check if the issue persists.

1. Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’, or run Task Manager and fully kill the process.

2. Go to File Explorer, and type in %appdata%Microsoftteams.

3. Once in the directory, delete all the files and restart Teams.

NOTE: Kindly make sure that your Microsoft Teams application is always kept up-to-date. Visit: Update Microsoft Teams

Yes, you can access Microsoft Teams via supported web browsers using this link: https://teams.microsoft.com.

Supported browsers are: Microsoft Edge (RS2 or later), Microsoft Edge (Chromium-based), Google Chrome, Safari 14+, Safari 13.1+, Firefox.

Make sure that the browser you are using is up-to-date.


Following are few browser limitations during Teams meetings:

1 To give and take control of shared content during sharing, both parties must be using the Teams desktop client. Control isn't supported when either party is running Teams in a browser.

2 Blur my background isn't available when you run Teams in a browser. This feature is only available in the Teams desktop client.

3 Teams meetings on browsers are limited to a single incoming video feed of active speaker.

This is a new feature (know as a meeting lobby) we have activated for all Teams meetings.

It is not an access issue. Students are no longer able to join meetings directly. They need to wait till the teacher joins the meeting and let them in.

This issue occurs when you try to access a file using a different account.

Always ensure that you are logged in from your own account and access the file you need via Microsoft Teams.

This happens because you are not logging into the meeting properly.

You should enter the meetings through the Microsoft Teams app using your College email account.

To download and access the Teams app through your PC/mobile, see: https://trinitycollege.lk/learning-at-home-microsoft-teams/

Many issues regarding communications with parents have surface over the past several weeks. In a few cases, the database of contacts at the school has been incorrect, or requests for changes have not been included. However, in many other cases, parents have changed their mobile number without informing the school or have started using an additional number and are neglecting to read SMS on the number that is with the school.
