I have been using and loving Axcrypt for years. Last night, as usual, I axcrypted my Outlook file before uploading it to my online backup. Today, I've decrypted several files, but when trying to decrypt outlook-pst.axx, I got the following message. Please help! I need this file daily. Thank you.

<
Axcrypt 1.7.2976.0
An error occurred when unwrappping [sic] outlook-pst.axx.
The file does not appear to be produced by Axcrypt. GUID mismatch.

    Hello,

    This indicates that the file is corrupted. It may have been corrupted during upload or download. It can also become corrupted if AxCrypt is interrupted before being done with the encryption, such as when a USB memory stick is removed prematurely.

    You may want to try undelete the file you uploaded on the PC where you worked with.

    Thanks, Svante. I had shut down in a hurry BEFORE backing up, so it's possible I had interrupted encryption. Silly me! I have restored from the previous day's backup. I hope I had no critical additions that day, I don't think I did. Might I be able to restore this bad file if I've gotten the meta info? Thanks again.

    Happy that you have a working backup scheme!

    I'm afraid that the chance of recovering the broken file is very small.

    Thank you for your quick response. I had hoped I could use the meta info to get my updated file, as I had done some reorganizing of my folders that day. But I can live with a few lost hours of work so long as I've got my data! I'll consider this issue closed. Thank you again for your help.
