Do you think this issue describes your problem? https://support.mozilla.org/en-US/questions/1120683

I have him doing one thing, perhaps we can try something else with you. In the end a log might be the answer, but this is less painful.

Could you please right click the account in the folder pane, select settings and in the server settings. Check allow immediate server notifications. Clean up ("Expunge:) inbox on exit Restart Thunderbird

Any change?

If not try changing the When I delete a message. In particular the "just mark it as deleted"... the deleted mail will appear in your inbox with a line through it until Thunderbird restarts.

Charter has two settings for emails. One uses mobile.charter.net and the other uses IMAP.charter.net, I have tried both. The server type in both is IMAP.

If Thunderbird accesses an email Charter.net shows that the email has been read. So somehow Thunderbird is accessing the email in Charter.

What does the Expunge option do? Is it going to remove emails from my inbox? As it is if I exit Thunderbird or take it off line all emails that should not be in the inbox are removed.

Expunge should do what going off line does. Expunge the deleted mails. Compacting the folder in Thunderbird should force the same thing. especially with expunge turned on.

...At the time Charter said they were having problems so I assumed it was their problem. Now Charter says they have fixed their problem and I am having problems with Mozilla. They said Mozilla had not implemented modifications needed to interface with their modifications.

That's brilliant. If they know of such information they should also be able to cite a URL or quote the details of what they fixed and what Thunderbird needs to implement. Can you go back to them and ask for those details please?

The problem still exists.

The people you talk with at Charter do not have a clue. I called today and the person I talked with told me all kind of things, which were incorrect. When I pushed the issue he checked and found out that I was not the only one having the problem and is supposed to be fixed in a quarterly update, but of course he could not tell me when that would be.

Here is what I can tell you:

1. When I bring up Thunderbird I receive emails. Some of the emails may be moved, via a rule, into a local folder. This will trigger the problem where Thunderbird stops receiving emails.
2. If I look at the emails, in the inbox, via Thunderbird, and delete one the email is in the Trash folder on Charter.net. This will also trigger the problem.
3. If I go to Charter.net emails that have been deleted via Thunderbird are in the Trash folder and the inbox. Thunderbird shows them in the Trash folder only.
4. If I go to Charter.net emails that have been moved via Thunderbird are still in inbox.
5. If I go to Charter.net and delete one of the emails that should not be in the inbox all of emails that should not be in the inbox are deleted and Thunderbird starts receiving emails until one of the conditions occurs that triggers the problem.
6. Another way to get Thunderbird to start receiving emails is to take Thunderbird off line and then put it back on line.

Charter will tell you they do not support Thunderbird and if Charter.net functions correctly they do not have a problem. When I asked them to explain how an email can be in both the Trash and Inbox folders on Charter.net they said that was a problem and it would be escalated. That was some time ago and I have given up.

I don’t know who or what has the problem but what I can tell you is that this use to not be a problem until Charter changed something, who knows what, they just say they changed something.

It just so happens that I purchased a Samsung tablet about a month ago. It seems that the email, using the Samsung application, functions correctly.

Just to test, modify your filter to copy the message and then delete. (A long hand move) Move has a special meaning in IMAP and if Thunderbird is doing it's thing correctly should be going the copy delete route anyway in the background.

Can you supply a log for the connection? https://wiki.mozilla.org/MailNews:Logging#Windows

These logs get very large very quickly. so do the minimum to force the issue and then exit Thunderbird.

What size is the log you created?

I finally got to someone high enough in Charter to look at the problem. They acknowledge there is a problem that they think they can resolved. The suggested waiting a week before doing anything. Can I get back with you next week?

> Can I get back with you next week? Sure

> I finally got to someone high enough in Charter to look at the problem. A support person?

I still have not heard back from Charter, but here is something I discovered that might give a clue as to what is happening.

Someone along the way told me, and it may have been you, that when a message is moved or deleted Thunderbird has the responsibility of deleting it from the Inbox. Yesterday when I was working with Charter I was in my email on Charter.net. I looked at some emails and deleted them from Charter.net. Thunderbird was up during all of this. When I looked at the Inbox on Thunderbird it was showing the emails as they were prior to me accessing them via Charter.net.

I just tried a test. The problem exists since I brought up Thunderbird and it moved some emails. I am able to send an email from Thunderbird and it shows up in the Inbox on Charter.net, but not in the Inbox on Thunderbird.

Last night when I saw that the two Inboxes were not in sync I exited Thunderbird. When I brought Thunderbird back up the two Inboxes synced up.

I think the problem is that, for whatever reason, Thunderbird cannot access the Inbox on Charter.net. I don’t know if that is a problem with Thunderbird or Charter. I don’t know if Thunderbird is waiting on Charter to do something or if Charter is waiting on Thunderbird to do something, but something gets reset when I take Thunderbird down and back up. If I look at Charter right now it shows that all of the emails moved by Thunderbird have been read but they are in my Inbox.

As a test I had an email open and the Inbox open in Thunderbird. I exited the main screen for Thunderbird leaving the email open. I went to Charter.net and clicked on the icon to get my emails. Nothing changed. I then exited the open email. I went back to Charter.net and clicked on the icon to get my emails. This time the Inbox was accurate. I brought Thunderbird back up and it started receiving emails again. Since the email I sent in the test was to myself I have a rule to move emails from me to me into a folder. So now the test email has been moved, Charter.net shows it as being read, it is still in the Inbox on Charter.net and the problem exists again.

I don’t know if Charter is not following some protocol rule or if Thunderbird is not following some protocol rule, but I feel that one of the two is not following all the rules.

I can tell you that if there are multiple emails in the Inbox on Charter.net that are not in the Inbox in Thunderbird if I take Thunderbird offline and back online I will receive one of those emails. If I same thing exists and I exit Thunderbird and bring it back up I receive all of the emails in question.

I communicated with Charter again. Not sure who I was talking with because they did not seem all that knowledgeable. At any rate they wanted me to uninstall and reinstall Thunderbird. I was nervous about doing that, but it just so happens that I had my granddaughter's PC and I installed it on that with the same results.

I am totally convinced that the problem is in synchronization. Do you know how Thunderbird syncs with the Charter server?

I am using IMAP. Is there a setting that could be modified that deals with synchronization.

They kept talking about a delay between the Mozilla server and Charter. I told them that I thought there was no Mozilla server. That Thunderbird went right to the Charter server. Am I correct?

At any rate they are going to make sure the next people up, whom ever that is, are aware of what is going on. It now has occurred on three different PCs running Thunderbird to Charter. This problem only began when the made a modification.

You are correct about there being no Thunderbird server.

You are not the only charter user on this forum to report problems. We think they have a problem but they are in denial, or incompetent to fix it. Their usual get-out-of-jail card is to steer you towards their website.

I wish you luck in finding someone there to talk to who understands the problem.

Charter tells me it is not their problem. You wanted me to create a log file. I have a question.

1. Do I run the bat file and then start Thunderbird or create the problem and then run the bat file.
2. When I exit Thunderbird does the log file stop or do I reboot.

Run the batch file. Use Thunderbird so as to provoke the error condition. Exit Thunderbird. Logging will stop.

Your log file for that session will now be in the location set in your batch file.

I'd suggest that then you need to contact Matt to arrange sending him a copy of the log file.

I'd like to see it myself. xenos at gmx dot co dot uk

Your email is xenos@gmx.co.uk? How do I get in touch with Matt?

beside my posts on this forum is my name... click it to get the email address.

Once I have it I will try and figure out Gmail sharing. Otherwise I will forward it to you Zenos.

Why mess with gmail sharing? We need something for lots of these issues if I can figure it out it is a more private location for the masses of data the logs will contain.

I would like to draw attention to this bug., where excerpts from the log are quoted. https://bugzilla.mozilla.org/show_bug.cgi?id=1258429

Even though it is marked invalid (we have no bug charter does) any new information is likely to appear there first.
