Fix Acrobat Online Request a Signature Errors & Limits
Question details
The user needs to understand why a generic error occurs when sending a document for e-signature via Acrobat Online and how to resolve it.

- Product
- Adobe Acrobat Online
- Device & OS
- not provided
- Scenario
- Sending a PDF document using the Request a Signature online service.
- Observed behavior
- The system displays a generic error message and fails to process the signature request, typically because the user has hit the free tier's transaction limits.
Check your Adobe account's recent transaction history to confirm exactly how many signature requests you have initiated over the past month.
Wait for the 30-Day Transaction Limit to Reset
Determine if you have exceeded the free tier's two-transaction limit and allow the rolling timer to reset.
The free Acrobat Online Request a Signature service strictly allows only two transactions during a rolling 30-day period. Once both transactions are used, the system often throws a generic error instead of a clear warning. Uploading a newly encoded PDF, changing your browser, or clearing your cache will not bypass this account-level restriction.
Sign in to your Adobe account on the Acrobat Online portal.
Navigate to the 'Documents' or 'Sent' tab to count how many signature requests you successfully sent in the last 30 days.
If you have sent two documents, you must wait exactly 30 days from the time each document was sent for that transaction slot to become available again.

Frequently Asked Questions
Why does Acrobat Online give a generic error when I request a signature?
This usually happens when you exceed the free tier limit of two signature requests per 30 days. The system fails to process further requests and often displays a non-specific error instead of a clear limit warning.
Can I bypass the Adobe signature limit by using a different browser?
No. The transaction limit is tied directly to your Adobe account, not your browser or device. Changing browsers, clearing cookies, or uploading a differently named PDF will not reset the limit.
How long do I have to wait to send another signature request?
You must wait exactly 30 days from the time you sent your first or second request. The limit operates on a rolling basis, meaning each slot frees up 30 days after it was specifically used.
Are there alternative ways to sign PDFs without these strict limits?
Yes, desktop software like WPS Office provides robust built-in PDF tools that allow you to insert electronic signatures and share documents directly, bypassing the strict limits often found in free web-based services.
