Thunderbird Community Forum

I recently updated the computers at my shop. My shop uses an older program Mitchell 1 to process and organize invoices. I have used Thunderbird to email invoice pdfs for the longest time but now after updating I get “ERROR SENDING EMAIL. MAPI RETURNED -2147467259” it’s my understanding MAPI is outdated but I figured Thunderbird would still support this function.

I created a backup of my Thunderbird in Debian. When I try to import the calendar data from backup.zip, I only get the names of the calendars, but not the contents! How can I test whether there is any calendar data? Many thanks for any advice, Günter

Lately, when I try to click on a different mailbox or message , nothing happens. repeating clicks sometimes works, and sometimes i have to first click on what I was previous viewing to get what I want to highlight, or click on different areas of a message or mailbox to get it to work. I am on mac tahoe 26.2. Did not have this problem before. What can I do to fix this problem?

Thanks Dan

I have a new issue with Event invitations.

Previously if I received an invite, the email would display a button to accept, and if I accepted it would - send an email response - add it to my Thunderbird calendar.

Now if I receive an invite, there is simply a blue banner at the top saying "This message contains an invitation to an event".

It usually does not show the event details at all, and there is no integration with calendar. No button to accept no way to interact with it.

Until the latest ESR update of Thunderbird, invitations worked perfectly. I switched to Release update (v147) and still seeing the same issue on Macos.
