Solution 1Recommended

Re-authenticate Your Account Session

Refreshing your local login session resolves authorization conflicts caused by recent changes to your account username.

When an account username is modified, the local application token may become out of sync with the cloud entitlement server, leading to permission errors when accessing premium services like e-signatures.

1
Sign Out of the Application

Open Acrobat Pro DC, click on your profile icon in the top right corner of the window, and select 'Sign Out'.

2
Close the Software

Completely close the application to ensure all background processes tied to your old session are terminated.

3
Sign In with New Credentials

Relaunch the application and sign in again using your updated username and password.

Re-authenticate Your Account Session
Session Refreshed: Re-authenticating forces the application to fetch your latest permissions, typically restoring your access to the signature service instantly.

Frequently Asked Questions

Why does changing my username trigger an 'Access Denied' error?

Changing your username can cause a mismatch between your local application's active session token and the backend entitlement server, temporarily blocking your access to premium features like sending for e-signatures.

Will I lose my pending signatures if I sign out and sign back in?

No, documents that have already been sent for signature are stored securely on the cloud service. Signing out only resets your local application session and will not affect pending documents.

How can I check if my e-signature entitlement is currently active?

You can log into your account via a web browser and navigate to the Plans and Products section to ensure your active subscription still includes e-signature capabilities.

Can my organization's IT admin fix this without contacting software support?

Often, yes. Your IT admin can re-assign your e-signature permissions in the admin console, which forces a sync with your newly updated username and resolves the error.
