Display multiple BCC recipients not working

more options

Hi,

After migration from a unix mail server to an on premise Exchange server we started to use ExQuilla in Thunderbird and now have an issue with multiple BCC recipients not showing up in Thunderbird. As you can see in the attached screenshot the headerinformation contains more than 1 address but only the first one is displayed when printing/reading the mail.

Checking the mail in OWA reveals boths BCC recipients so it's a Thunderbird error. Prior to the change to Exchange we did not experience this issue.

Running the latest Thunderbird and ExQuilla addon + Exchange 2016

If it is your own server, why are you not using IMAP and SMTP instead of an add-on? Turning on IMAP and SMTP in exchange a as simple as toggling a couple of settings.

See https://docs.microsoft.com/en-us/exchange/clients/pop3-and-imap4/configure-imap4?view=exchserver-2019

Note the article talks of SSL. This is disabled in Thunderbird. TLS only is supported.

Sadly IMAP is not an option, we need the Exchange connectivity function for us to work in this case.

My personal choice when I was faced with this issue was to use davmail. At least it has a team of developers maintaining it. http://davmail.sourceforge.net/

Exequilla has a limited life. Or so Kent James said when he turned it over to the community. He has basically reiterated that opinion recently. https://github.com/rkent/exquilla/issues/2 which is why I am not really addressing the issue as much as suggesting alternatives. Those using it ghat about a year.

You are however quite welcome to raise the issue with the author at the link I have provided.

You might also look at this add-on https://addons.thunderbird.net/en-US/thunderbird/addon/eas-4-tbsync/ as activsync is usually made available for phones.

Thanks for the links, I've tested tbsync and imap. This should be working for us, since it offers all features needed.
