Thunderbird is slow to respond to ISP server and email messages have too much info added when I forward them.

Best Buy installed a new hard drive with additional storage capacity on my computer. A lot of stuff got wiped out and had to be re-installed, including Thunderbird. Now, Thunderbird is slow to respond to the server and even simple reply messages can take a minute or longer to send. It takes a long time to get messages, send, etc. What can I do to increase speed? My ISP tells me I have 45 MB of speed [soon to be 300mb] and that something is slowing down the email process, not them. Also, when I forward a message Thunderbird sends all the coded info with the messages that confuses the receipient. For example, if I send a political cartoon, some will delete the message because the cartoon is on the very bottom of the message and all the sending material is first and he thinks the message is a gag of some sort. Messages used to just show the sender and receipient(s) names and topic, not all the unnecessary detail involved in the message itself.

Can you please me with these issues, as I am so frustrated that I am exploring using Gmail or Outlook instead.

Thanks. Jim Maciej jvm1@windstream.net

Chosen solution

Try to start Windows 10 in safe mode with networking enabled.

Still in Windows safe mode, start Thunderbird in safe mode. Does the problem go away?

Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.

What is your anti-virus software?

Thanks for the reply. Thunderbird version 128.2.3esr (64 bit). Thunderbird states that it is up to date. I'm using Best Buy's Webroot Secure Anywhere which has an antivirus component. Email process still is slow to react. As far as the coded info with messages, your suggestion appears to have solved the problem.

Anti-virus software is known to cause corruption of Thunderbird mail files. Create an exception in your anti-virus software for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_how-to-find-your-profile
