I am with desktop support and one of our clients has your thunderbird email encryption software installed. She was using it on a mac and a pc with 2 separate keys and the same email address. The encryption never worked on the pc, only the mac. She wants to move everything from the mac to the pc and get to where there is only 1 key. We ended up revoking both keys Friday and now she has none but she is getting encrypted emails and thinks she can open them if she had her revoked key back. Please provide some information regarding this issue. My contact info is x and my cell number is x. Any assistance with resolving this issue would be greatly appreciated.

start with a fresh install and fresh key so we revoked the 2 keys which included the key that worked on the mac.

You didn't explain what you did to revoke the keys. As said before, whatever you did, revoking the existing keys was completely unnecessary.

(this key never worked on the pc).

Not sure if this still matters, but what does 'never worked' mean exactly?

In case it isn't obvious, a recipient can only decrypt a message using the own private key, if the sender encrypted the message using the recipients public key.

So in order to be able to decrypt messages again, you'd need to create a new key pair, and distribute the public key to all communication partners to be used to encrypt future messages.

What encryption software? Please be more specific.

We ended up revoking both keys

Why? That wasn't really a smart move. In any case, please explain in detail what you did.

The user has a HP laptop with Windows 7 and email is microsoft exchange/office 365 account. The macbook pro she was using previously had OSX Sierra and the same exchange server. For encryption purposes, GPG 4win 2.3.3 and Thunderbird 52.1.1 was installed on the pc.

Now, originally she got the mac (in addition to her pc) for the email encryption as she was told it only worked on the macs at the time. She was having issues with her key and so another one was created for her under the same email. This led to her having 2 active working keys on her account. All this was on the mac. After getting the 2nd key, she was able to unencrypt her mail and read it. Recently, she received some encrypted email from a client and could not open them with her key. Other people in the office with pc's started getting the software installed and working. She contacted me and said she wanted to get her encryption working on her pc and totally drop using the mac. We began working on getting her pc encryption up and working. After a few hours, she just decided to drop all the encryption completely and Monday, start with a fresh install and fresh key so we revoked the 2 keys which included the key that worked on the mac. (this key never worked on the pc).

The short version..she wants to use the encryption on her pc only and have only 1 working key and have all her clients updated as well.
