Try the master password... if that fails too, try a different PDF reader.  I couldn't open a password protected PDF on my workstation (with Adobe reader), but copied to my home PC (with a different PDF reader) and it opened just fine.

I did try to open in a different reader, but same issue. What do you mean by 'Master Password'?

I wasn't aware there was a Master password to use.

Thanks!

I've only used this for invoices / orders, but assume it works the same for PR forms.

I was able to locate where this is. I believe it does work, but not sure what it will do to all employees who are without problem. I certainly hesitate to create a mess for so many when only having an issue with one. 

Look at Knowledgebase Article 69065 which covers resetting the master password.  I don't have any good ideas as to why 1 employee is having trouble.  I suggest posting in the technical thread, since this issue is technically a paperless office issue, not payroll.  

Is she ever able to open the pdf, or never?  I have a client with one employee who sporadically can't open it, but other times it's fine.
