Unable to edit existing user on connect

Based on your issue with being unable to edit a user in Amazon Connect, there are a few potential causes and solutions to consider:

If you're using Amazon Connect with an external identity provider (similar to the AWS SSO scenario), you may need to manage users through that external system rather than directly in Amazon Connect.

For Amazon Connect specifically, you should check that your account has the necessary "Users - Edit" permissions to modify user information. Without these permissions, the edit functionality may appear grayed out.

If you have the proper permissions, you can try these approaches:

1. For individual users, you can update their information using the Amazon Connect console or programmatically via the API/CLI (specifically the UpdateUserIdentityInfo API).

2. For multiple users, the bulk edit feature might be available - select the users you want to update and choose "Edit" to enter bulk edit mode.

If the user management is still inaccessible, you may need to check your identity source configuration. If automatic provisioning (SCIM) is enabled, you might need to disable it to regain direct user management capabilities, similar to how this works in AWS SSO.

If none of these solutions work, I recommend contacting AWS Support for assistance with your specific Amazon Connect configuration.
