CAA2000B Error

Question

Hello everyone!

I hope this message finds you well. I'm reaching out because I've encountered a persistent issue with connecting to Word since renewing my developer program subscription. Each time I attempt to access Word, I receive an error message indicating a problem with connectivity (CAA2000B).

Despite confirming my program subscription, I've been unable to resolve this issue on my own. Given our pressing need for access to Office 365, I'm reaching out to request your assistance in finding a solution as quickly as possible.

Your help in resolving this matter would be greatly appreciated. Thank you in advance for your prompt attention to this request.

Dear respected Syham Koffi,

Good day! Thank you for posting to Microsoft Community. We are happy to help you.

I’m sorry you’re having a problem but based on your description we can work together to resolve it.

For the situation you encountered, we deeply understand the inconvenience caused and apologize for it.

As per your description, If you locate Microsoft 365 admin center>Users>Active users and check the licenses of a user, what licenses would the user have?

For example:

Firstly, please you may need to make sure you have an active license assigned which includes Office desktop license.

If you have correct assign license then I think this issue might be raised by your local environment (Settings, Registry).

 Given this situation, maybe the local settings had affected the application. Thus, we would like you to check whether the issue is related to your user profile. In this situation, we suggest you Create a new user account under your Windows(for test purpose). See if it still alerts you with the same error message. It is worth trying because it will help you narrow down whether the issue is caused by a specific corrupted user profile.

We appreciate your understanding that sometimes the initial suggestions may not resolve the problem very soon. However, we can work together to narrow down and resolve the situation. So, please kindly provide more information below to let us work further.

1. The screenshot of the subscriptions page “Office 365”.

2.Confirm whether other applications also get the same problem? Such as PowerPoint or Excel and etc.

Please understand that our initial reply may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution.

Appreciate your patience and understanding and thank you for your time and cooperation.

Sincerely,

Waqas Muhammad
