The print screen has only one option to 'Save to PDF' and I want to replace that to 'Print' I've checked the settings and everything for email in there except 'Print'. How do I get to a setting screen where I can make this change. I am old and not computer savvy so please give me every step so I can finally print attachments. Thank You

I'm using a X13 ThinkPad with 1920x1080 resolution on a 13'3 display with Linux (Arch) and XFCE desktop. For the best results I've increased the XFCE's DPI to 134 and fonts sizes to 10. It looks like the fonts of the size ~13 without DPI change. It's fine, and applications like Firefox like those settings.

In Thunderbird I've set the font size (interface) to 12 and in Settings the default font sizes for Latin and Other Writing Systems to 12 (both) and finally the interface font as well as plain text email and HTML e-mails without font sizes specified explicitly look natively and perfectly.

But there are some senders using clients that generate HTML e-mails and specify the font explicitly as 'font-size=12pt' in their body by default. The same as my 12 so everything should be fine. Unfortunately font in those e-mails is really HUUUUGE! I'm wondering if there is some setting that allows custom scaling but only the HTML messages. Or some pt to px custom scaling for HTML? Or some maximal size allowed in HTML?

Good afternoon.

I will describe the problem step by step. There is a mail server. It has a web version of mail (SOGo). Created an account for the meeting room. Created a shared calendar and signed mail users with rights to create entries in this calendar. In mail clients connected calendars over the network with user credentials. When creating an event in the calendar, added participants. Participants receive an email with an invitation. Immediately, when the email arrives to the participant, there are buttons to accept, but as soon as the event is synchronised and added to the calendar, the buttons disappear. Why? An error occurs when clicking on the refresh button. Why? How to set up a shared calendar correctly? Is there any instruction?
