Adding certificate to gpgOL in Microsoft Outlook

Gpg4win help-en
1

I have received an encrypted email and Outlook says that it can´t open it, writing:

“No secret key found to decrypt the message. It is encrypted to the following keys:”

Normally I use Kleopatra and it works just great, but now I can not see any part of the message or have access to the attachment.

I try to find out, but looks like I´m too noob to know htf add my certificate in GpgOL/Outlook.
I´m using:

Microsoft® Outlook® for Microsoft 365 MSO (Version 2504 Build 16.0.18730.20122) 64-bit

Which version of Gpg4win have you installed?

Did that message list your key? If not than it’s not your fault that you cannot decrypt the email.
