- Product
- Adobe Reader XI
- Device & OS
- not provided
- Scenario
- Attempting to share or send a PDF document directly through email within Adobe Reader XI.
- Observed behavior
- The application completely freezes during the email handoff, blocking further actions and requiring the user to force-close the program via Task Manager.
Before proceeding with the solutions, verify the file size of the PDF you are trying to send, as extremely large documents can cause the email client integration to time out or freeze.
Use Web-Based Adobe Send
Bypassing the local application to send the file via a web browser often avoids the freezing issue completely.
If the desktop integration is failing, utilizing Adobe's cloud-based transfer service ensures your file is sent without relying on your local email client's MAPI configuration.
Open your preferred web browser and navigate to https://cloud.acrobat.com/send.
Sign in with your Adobe ID credentials.
Upload the PDF document you wish to share and follow the on-screen prompts to send it directly via email through the web interface.

Update Adobe Reader XI
Outdated software can cause integration bugs with your email client. Updating to the latest patch can resolve known freezing problems.
Test with a Different PDF File
This helps determine if the issue is caused by the specific file size or document corruption rather than a software failure.
View and Email PDFs Seamlessly with WPS Office
If Adobe Reader continues to freeze, WPS Office offers a reliable, lightweight built-in PDF reader. You can open, view, and directly email your PDF files without experiencing annoying system hangs or crashes.
- 1. Open your PDF in WPS: Launch WPS Office and open the PDF file you want to send.

- 3. Send the file instantly: Select your email client and send the document effortlessly without any software freezing issues.

Frequently Asked Questions
Why does Adobe Reader XI freeze when trying to send large PDFs?
Large files take significantly longer to process and attach to your email client. If the software handoff between Adobe Reader and your email application times out during this process, the program may freeze.
How do I regain control of my computer if Adobe Reader freezes completely?
Press Ctrl + Shift + Esc (on Windows) to open the Task Manager. Locate Adobe Reader XI in the list of active background processes, right-click it, and select 'End Task' to force the application to close.
Does my default email client affect Adobe Reader's ability to share PDFs?
Yes. If your default desktop email program (such as Outlook) is improperly configured, missing updates, or not set as the default MAPI client in your operating system settings, Adobe Reader will struggle to communicate with it, often leading to a freeze.
