Since update to MS Office 365 Pro Plus (Version 1908) the gpgOL PlugIn doesn´t work any more.
If I receive an encrypted email I get following error message: "OpenPGP Encrypted message (decryption not possible)" "Could not decrypt the data: Unsupported protocol"
If I want to send an email encrypted I get following error message:
This is usually caused by a bug in GpgOL or an error in your setup. Please see https://www.gpgp4win.org/reporting-bugs.html or ask your Administrator for support. Code: 1"
I already re-installed gpgOL without any success.
