thunderbird trying to access mailserver that requires ESET 2FA

Hi, I am using Thunderbird as an email client. I don't use any ESET product myself, but I have to retrieve mail from a an Exchange-mailserver that requires ESET 2FA. The first login step seems to work, and then an ESET-authentication window pops up but the contents of the window remains blanc, so there is no way to enter my one-time code. This happens both if I approach the mailserver as an Exchange server, and if I approach the mail server through the OWA-protocol (using Owl). Known problem? Any suggestions? Should this be an issue for Thunderbird or for ESET?

I suggest you pursue this with the OWL addon vendor, as this seems Exchange=specific.
