Fix Adobe Send and Track Email Errors After a Windows Update
Question details
The user is unable to send PDF contracts for signature due to a 'Cannot send. Try again' error in Adobe Send and Track following a recent Windows system update.

- Product
- Adobe Reader
- Device & OS

- Scenario
- Sending PDF contracts for electronic signature via Adobe Send and Track or a desktop email client.

Ensure your computer has a stable internet connection and verify that your default email client (such as Microsoft Outlook) is properly configured and capable of sending standard emails before troubleshooting Adobe Reader.
Update and Repair the Adobe Reader Installation
System updates can sometimes corrupt application files or registry settings. Updating and repairing Adobe Reader will restore default configurations and resolve software conflicts.
Windows updates occasionally interfere with the background services and registry hooks that third-party applications use to communicate with the internet or your local email client. Running Adobe's built-in update and repair utilities is the most effective way to re-establish these connections without losing your personal settings.
Launch the Adobe Reader DC desktop application on your Windows computer.
Navigate to the top menu bar, click on 'Help', and select 'Check for Updates'. Follow the on-screen prompts to install any available patches.
If the problem persists after updating, click on the 'Help' menu again and select 'Repair Installation'.
Wait for the repair process to finish, then restart your PC to ensure all system and registry changes take effect before trying to send your PDF again.

Update Your Desktop Email Client
If you are trying to send the file through a local email client rather than Adobe's cloud service, updating the client can fix integration bugs caused by the Windows update.
Seamlessly Manage and Share PDFs with WPS Office
Tired of encountering software conflicts and integration errors after system updates? WPS Office provides a robust, lightweight, and completely free alternative to Microsoft Office. It features a powerful built-in PDF toolkit that makes viewing, editing, signing, and emailing documents incredibly smooth, bypassing the need for complex third-party trackers.

Frequently Asked Questions
Why does a Windows Update cause errors in Adobe Send and Track?
Windows updates can occasionally reset default application associations, modify system security protocols, or alter registry keys that Adobe Reader relies upon to communicate with your email client or internet services.
How do I change my default email application for sending PDFs?
In Windows, go to Settings > Apps > Default apps, find 'Email', and select your preferred client (like Outlook). Within Adobe Reader, you can manage this by navigating to Edit > Preferences > Email Accounts and setting your default sending method.
What should I do if the 'Cannot send' error continues after repairing Adobe Reader?
If a repair does not resolve the issue, try completely uninstalling Adobe Reader from your system. Download the latest installer directly from the official Adobe website and perform a fresh, clean installation.
