I can't download emails using Thunderbird. I have a Comcast email account and they just changed their email formatting. I had not downloaded emails since 12/26 and on the 27th my Windows 10 system implemented the "Creator Update" 1709. I get emails from Comcast on my Samsung Galaxy S6 Android based phone. No other changes occurred.

Have others seen this problem?

I booted my computer in "Safe mode with Networking" and then started Thunderbird in safe mode by holding the shift key down while clicking on the Thunderbird icon. Once the app came up I hit "get messages". The program behaved as before in regular startup.... The approximate notices at the bottom of the T-bird window are: "Contacting server" "checking for messages" "no messages to download"

I have an Android phone (Samsung) that see's my email account and I've tried searching for a setting that might mark the messages in my inbox as read or downloaded but I don't see any selections that would affect the emails on the server.

I'm tempted to go back to a restore point of my system before the Dec 26th "update" of the OS. Unfortunately, two significant changes happened in my email/OS world. The Windows 10 / 1709 upgrade was finally successful. Comcast changed their native email program. I have since found that the driver for the HP Laser Jet 1320 is gone and the printer isn't visible. So there are multiple "ghosts" in the system.

The Windows 10 / 1709 upgrade has numourous reports of causing all kinds of problems, not just in thunderbird, so not everyone had a succesfull experience with that upgrade.

re :I have since found that the driver for the HP Laser Jet 1320 is gone and the printer isn't visible. seems you went back to a restore point prior to when you installed that printer. Reinstall the printer and select it as default printer.

re :I have a Comcast email account and they just changed their email formatting. Perhaps you mean server settings. Post the setting you currently are using, so forum understand current setup. In Thunderbird Help > Troubleshooting Information click on 'Copy text to clipboard' button In this forum question, right click in a 'Post a Reply' text box and select 'Paste'.

Restore points - I've never had a great experience with that.

Too bad safe mode didn't help

The troubleshooting information requested follows. Nothing changed in my system settings. Curiously, as I was looking through the account settings looking at the server info. As I went from my "Server Settings" page showing the local directory at the bottom to the "Copies & Folders" link I get the following notice "A parent directory of the directory specified in the Local Directory setting is already used by the "Local Folders" account. Please pick a different directory." I have not seen this message before and as far as I know there has been no change in the account settings unless the Win10 upgrade modified something some how. I wouldn't think this would lead to the notification that there are "no messages to download".

You are using port 110 for inbound. This is an unsecured port and you should change it to port 995, SSL/TLS., Normal Password

You outbound port is ok but you need to add SSL/TLS for the Security Connection instead of None.

Right click the account on the left side in the Folder Pane and select Settings. Then Server Settings. This is for Inbound.

For Outbound scroll all the way to the bottom of the Folder Pane and select Outgoing Server(SMTP) Make the outbound chage there. Exit Thunderbird and restart it.

Any better?

Before trying the port and SSL related changes I did a restore process reverting back to the previous Windows version. I didn't have any options as far as selection the version to return to I just went to Windows recovery and the process of going back a version. So I'm not sure what version of Win 10 I went back to but assume it was the one before the 1709 update. I seem to recall, dimly, that I had tried changing some of the SSL related settings and it didn't go well. I can't remember the problems I had. At any rate, after I did the system recovery process my laser printer works and Epson scanner software works BUT I am not yet able to download emails. So, assuming that returning the system has given me a better chance at downloading emails and the fact that I'm still seeing the same problem I'm beginning to suspect the upgrades/changes that Comcast made to their email handler/server may be contributing to the problem. I have a request for help in with Comcast. The server settings shown above are the ones I've been using for months if not years without a problem except perhaps for the security concerns which I'm willing to accept for the timebeing. I'm a little reluctant to change the SSL/TLS settings and port ID unless it's pretty clear this is the root of my problem. It could introduce a variable that will muddy the picture. Any other possible reasons for the sudden hiccup? It seems odd that it appears that response time from Comcast's email server has lengthened substantially. Thunderbird seems to be able to communicate and is able to check for messages but in the end doesn't see them or is unable to download them. I can send emails out.

more options

Suite yourself but you will not find port 110 anywhere in he Comcast recommended settings. https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email

It seems like several issues have been caused by the latest Win10 upgrade.

more options

Ok-- I went in and made the changes to the incoming server settings as you recommended. I didn't see an immediate way to change the outgoing SSL setting but will do that later since that works. I have closed/restarted and requested emails. In the end, the result was the same long delays at each step of connecting to Comcast/XFinity ending with "no emails to download" I've pasted the info from the troubleshooting page of T-bird below.

UPDATE------------ I set up a temporary account with Comcast/Xfinity so that I could go into Thunderbird and set up a new account to see if I could access emails from Comcast. I was able to get emails downloaded from Xfinity into T-bird. The difference is that in the new account on T-Bird I used the IMAP configuration. It doesn't appear that I can go back and change my existing T-bird account from POP to IMAP. I should also note that I have years of emails and folders in my existing account. In fact, I have 14000 emails in my inbox. I know my "Sent" folder gets full around 16000 emails and I have to clear it out. Am I seeing a similar issue with my "Inbox"?

I'm considering just moving my profile to the new account by copying the folders in my "broken" profile to the new profile. Is there a suggested method of doing such a thing? Should I consider other options first?
