MAPI Proxy: Decryption aborted
My PC is running PGP Desktop 10.1.1. The server uses the latest Microsoft Exchange.
My private key and my public key are on the keyring. My public key has been correctly uploaded to the PGP Global Directory.
The person with whom I want to exchange secure e-mails has given me his public key. I have imported it on the keyring, and signed. The other person has also imported my public key.
I can send signed and encrypted e-mails to him. That means I have got my private key (since I can sign) and his public key (since I can encrypt to him). He receives encrypted e-mails from me and can decrypt them properly.
He can send me encrypted e-mails (since he has got my public key).
However, when I receive his encrypted e-mails, PGP does not decrypt it. According to PGP log: ”MAPI Proxy: Decryption aborted”.
Now, I have gone through all the discussions in PGP forums. Whatever was available on the Internet. It is not the typical PGP/MIME problem. His key and my key are properly set to ”PGP/MIME” encoding. It must be something else. Can it be that he is NOT encrypting to my public key? Perhaps somebody from PGP could send me an encrypted e-mail using my public key from the PGP Global Directory, as a test? Just to check if the problem is at my end.
When I try to open his message by PGP Viewer I get the following error message: "Error: missing one or more decryption keys"
Any ideas what the problem is?
