The Exchange server has been working fine for over a year now and then this started out of the blue. When they receive a document in PDF format and open it in Acrobat Reader 6.x or 7.x it will sometimes give the error message: "The file is damaged and could not be repaired."
The problem so far only happens with a single company sending these files. I have been looking up articles online and have found that Exchange has in the past had problems with mime encodings and believe this to be the issue.
I have checked the properties on the particular PDF file after transfering it through HTTP and it was created using the following encoders to write the file:
PDF Producer: Amyuni Document Converter
Fast Web View: Yes
PDF Version: 1.3
The PDF files can also be sent using zip compression without any problems.
The problem I believe is some sort of new Acrobat encoding that is being miss interpreted by the Exchange server.
Any help that can be given will be much appreciated.
Once I have an authorized PDF to release as an example I will post it on our server... Until then I apologize.
