Fix Missing Send Button When Sending Large Files in Adobe Acrobat
Question details
The user is unable to send a large file because the Send button does not appear in the interface after entering the recipient's information.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Preparing and attempting to send a large PDF file for email delivery using the Adobe Send feature.
- Observed behavior
- The Send button completely disappears from the sharing pane, making it impossible to finalize and send the file.
Ensure you have a stable internet connection and save a local copy of your PDF document to avoid data loss before troubleshooting the online sharing service.
Refresh Adobe Send and Retry File Delivery
Since this issue is frequently caused by a temporary server disruption with the Adobe Send service, refreshing your session is the most effective way to restore the missing button.
Adobe occasionally experiences temporary outages or synchronization glitches that prevent the sharing interface from loading completely.
If you are using the web interface, refresh your browser page. If you are using the desktop application, close and restart Adobe Acrobat.
Log out of your Adobe account and sign back in to establish a fresh connection to the server.
Navigate back to the Adobe Send tool and reopen the large PDF file you were trying to share.
Input the recipient's email address and message again, then check the bottom of the pane to verify that the Send button has reappeared.
Use an Alternative Cloud Storage Link
If the built-in Adobe Send service remains down, you can manually generate a shareable link using an alternative cloud storage provider.
Share and Compress Large PDF Files Seamlessly with WPS Office
If you frequently encounter service outages or file size limits when sharing PDFs, WPS Office offers an integrated, highly stable PDF toolkit. You can easily compress large PDFs for direct email attachment or generate secure WPS Cloud links to share heavy files instantly without relying on third-party send services.
- 1. Open Your PDF in WPS Office: Launch WPS Office and open the large PDF file you need to send.
- 2. Select the Share Option: Click on the 'Share' button located in the top-right corner of the application interface.
- 3. Create a Cloud Link: Choose the option to upload the file to WPS Cloud and generate a shareable link to bypass standard email attachment limits.
- 4. Copy and Send: Copy the generated link and paste it into your email, messaging app, or directly share it with your intended recipients.

Frequently Asked Questions
Why does the Send button suddenly disappear in Adobe Acrobat?
The Send button usually disappears due to a temporary disruption or outage with the Adobe Send server. When the server fails to communicate with your app, the sharing interface cannot load completely.
How large of a PDF file can I send as an email attachment?
Most standard email providers limit direct attachments to 20MB or 25MB. For files larger than this limit, you must use a cloud-based sharing service (like Adobe Send or WPS Cloud) to generate a download link instead of attaching the file directly.
Can I compress my large PDF to send it without using a cloud link?
Yes, you can use PDF compression tools to reduce the overall file size. If the compressed file is under your email provider's size limit (usually 20MB), you can attach it directly to your email without needing a cloud link.
