Thunderbird Community Forum

I was trying to delete many hundreds of old emails and highlighted many that were unread at a time. (Shift, select emails and shift on the last one). They highlighted in blue. When I clicked on "delete," the blue highlight turned gray and nothing happened. Now I can't even go back in and delete them one at a time.

Is there a limit to the number of emails I can delete in one group? How can I delete the ones that are now gray (instead of bold black showing unread)?

I hope this makes sense. Thank you for any assistance you can provide!

When trying to add my outlook.com email account to Thunderbird 143.0.1, using the instructions at https://support.mozilla.org/en-US/kb/thunderbird-and-exchange, I get an "Exchange auth error." I'm able to add the account manually using imap, but I want to use Exchange so I can access my outlook.com calendar and contact when TB is updated to include them.

Hello Mail Merge used to work.

But now I get an Error: "NotFoundError - Node was not found".

It's a linux system, everything up to date.

Any ideas?

Hello. I accidentally made multiple copies of one folder and some of its nested folders. I can't move them back because the copy was already found in the main file. How do I remove the duplicates?

I clicked on something wrong and now I have a new "trash" folder as a subfolder under the "sent" folder. I cannot delete it and all my trash goes into it. The old one is still where it is supposed to be and stays empty. How can I delete the new one and send all my trash to the old one where it belongs?

I have no idea what I clicked on that created this problem.

Thanks for any help.

For months I have been working around a problem with Original HTYML message displays in my inbox. I have to revert to message body as Simple HTML for it to be readable. Please see the screenshot.
