Essentially, I’m wondering if thunderbird can be used to store old emails on a hard drive. I am wondering because I would like to be able to access them without the ability to use the internet because it would be on an old computer with no WiFi card or Ethernet capabilities. I would like to be able to store all of these emails with as little connected to the internet as possible.

My emails that I send usually have the same attachments, but sometimes the emails are returned to me undelivered for various reasons, but I have realised that in some cases it's because 2 of my docs (although in PDF) don't want to go through unless I send them separately. Is there a way of increasing the size of attachments I can send?

When I send photos from my phone to my imac inbox, same email address, or when a third party sends me a verification code, "get messages" is very slow showing results. Sometimes minutes, so I have to go through several verification attempts. The primary email account is gmail. My ISP is comcast.net. I don't know if this matters, because slow Get Messages is recent. It used to work very well

I have been using Thunderbird for 20+ years, maybe as many as 30. Forever. I have moved my profile across several versions of Windows and multiple computers. There are files in the root of the profile with a modified date of 2009. There may be older ones in sub-directories. There are 18 folders and 125 files. I suspect a lot of this is clutter left over from earlier versions of Thunderbird. In the Mail folder alone there are several hundred files and folders excluding the WDSEML files and actual emails.

I'm toying with the idea of starting fresh with a clean install of Thunderbird and getting on the correct release channel but I don't want to bring along what appear to be hundreds or thousands of unused files and folders.

I there anyone that can identify what profile files and folders to keep and what can be deleted?

Thanks for your consideration.

Shortening the file name of a .ics event allows it to successfully import in Thunderbird in Events and Tasks. Has this been addressed as a bug that could be worked on?

I have noticed that when a .ics file is not able to be manually imported into Thunderbird via the Events and Tasks there is a way to get it to import. Simply edit the filename of the .ics file to something very short (like less than 8 characters). I'm not sure why longer and more complex .ics filenames fail but shortening the filename almost always works.
