When generating a letter template to PDF, the document appears to be locked and edits can no longer be made.
During the 7.22.0 Release in June 2016, a security feature was added to generated PDF documents which makes them 'locked' upon downloading. This was added to make tax receipts and documents secure upon being downloaded from eTapestry, so the extra steps of making your document secure before sending to your donors no longer need to be taken. At this time, there are no plans to add a setting to the Communications area regarding downloading PDF documents as secure vs. non-secure.
If you need to make edits to your PDF document and do not need to utilize the security feature, you can follow these steps:
1. Download the document to Word instead of PDF 2. Click File 3. Click Export 4. Click Create PDF
