Excuse me, but some other more serious hints? Seriously me and a few colleagues have to work a few days on the computer in the "safe" mode? I assure you that everything is fine with systems, this is not the problem.

'Safe Mode with Networking' But only do this if you want to try to resolve the problem you are experiencing.

Alternatively, instead of involving all other colleagues at this point, only do 'Safe Mode with Networking' boot up on your computer and see if the issue disappears from your computer, but still occurs on other computers. That information would be invaluable.

So just to observe this problem I would need about a week - a week of work in the position in "safe mode" and it is irrelevant whether with the network or not. As I wrote earlier and I repeat it once again: it is not that I turn on the unit and I can see the problem right away, it appears after some time and it still looks like I am searching for a given email. The second case - the "safe mode" is to check / diagnose the system and possibly remove the failure with its start or operation. And here we have the case of the operation of one program, which was also tested in its safe mode. And it did not help. Not the way.

re : in "safe mode" and it is irrelevant whether with the network or not.

Are you asking a question or do you not know the difference? Booting up/starting a computer in 'Safe Mode' is not the same as booting computer up in 'Safe Mode with Networking'. It is highly relevant otherwise emails will not be downloaded if your computer does not permit access to internet. The computer must be started/booted up in 'Safe Mode with Networking'. Thunderbird can be started as normal.

I have no idea how frequently the problem arises, only you know that, but if it usually occurs at least once a week, then you would need to run the test for as long as it takes. Basically: Run computer in 'Safe Mode with Networking' mode until you see the issue of email not being downloaded. It may take a few days, it may take a week, you might be doing it longer and nothing happens. If co-workers are still starting computer as normal and they are reporting problems , but you (running in 'Safe mode with networking') are not having any problems, then over a period of a couple of weeks you should be able to determine whether the problem occurs whilst running the computer in 'Safe Mode with Networking'.

I know the differences in operation between one mode and the other. Only once again it is used for hardware diagnostics as well as programs and drivers that are launched when the system starts. And here we write about the mail client. This is not a hardware problem or drivers - how many times can I translate this? On other e-mail clients like Outlook or eMClient (which I use in parallel), the problem does not occur at all. The problem also disappears when you delete the IMAP account settings, the email folder and set everything again. I also do not think it is the fault of the equipment. I believe that the problem lies in the very core of the program in the implementation of the IMAP protocol - something with something can not get along. This happens only to me? I do not think so, just others do not pay attention to it or do not keep emails, e.g. from two years. Please, you received logs from the operation of TB, screenshots with a description of the problem and many other things, so I consider the diagnosis of hardware in emergency mode with the network as a waste of time - which shows a complete lack of your professionalism. What will happen next ... disk format and system reinstallation?

I have come to the conclusion that you are refusing to carry out the request to test 'Safe Mode with Networking'.

So therefore I cannot use it to diagnose or rule out possibilites.

re:, just others do not pay attention to it or do not keep emails Do not assume people are not aware of their emails. The problem you are experiencing in not common. Often the cause is the Anti-Virus interfering with the download. Please disable the ESET anti-spam toolbar from Thunderbird and wait to see results.

re: which shows a complete lack of your professionalism. There is no need to rude. This comment tells me more about you and your disrespectful attitude towards people volunteering unpaid free help to try to assist you in their own free time at absolutely no cost to yourself. Please desist from making unnecessary impolite comments.

You are very sure of that. Funnily enough I am not convinced in the slightest.

On other e-mail clients like Outlook or eMClient (which I use in parallel), the problem does not occur at all.

That is entirely not relevant, unless you are suggesting contention from multiple mail clients might be causing confusion at the server level as to what is going on.

The problem also disappears when you delete the IMAP account settings, the email folder and set everything again. I also do not think it is the fault of the equipment.

I would not be at all surprised to see it the cause of the real mode drivers loaded by ESET, but hey you already ruled out that possibility.

I believe that the problem lies in the very core of the program in the implementation of the IMAP protocol - something with something can not get along.

And yet you still appear to have an anti spam tools that is the most likely cause of the issue. Instead of working with folk to solve your issue you keep making unwarranted and unsubstantiated claims about what you think might be the problem.

This happens only to me?

Apparently

I do not think so, just others do not pay attention to it or do not keep emails, e.g. from two years. Please, you received logs from the operation of TB, screenshots with a description of the problem and many other things, so I consider the diagnosis of hardware in emergency mode with the network as a waste of time - which shows a complete lack of your professionalism.

I see no logs. Have you logged the imap operation without your anti virus or any add-ons running in Thunderbird so you can substantiate your statement that mail goes missing though Thunderbird's base actions? The link to do so it here. https://wiki.mozilla.org/MailNews:Logging

When you have a log showing Thunderbird doing an unwarranted deletion (without any anti virus or anti spam toolbars installed or other add-ons running) then I suggest you file a bug identifying exactly how a developer can reproduce the issue on their computer. They can not fix what they can not observe and reproduce. Note that IMAP logs are verbose and quickly get very large. so you will have to identify the exact actions, not upload thousands of lines of log. No one will have time to read it.

What will happen next ... disk format and system reinstallation?

Well from my perspective nothing will happen. You have refused to work with any one to help resolve your issues and simply stated being asked to do so is "unprofessional. Goodbye and good luck

re: I have been studying ESET for an angle and have already been excluded. Please look a few posts above.

Regarding the same: safe mode with networking ... It's the same as if I had a malfunctioning car with a broken engine and the mechanic insisted that you had to start by replacing the tires :)

But ok ... we will see this mode.

"You are very sure of that. Funnily enough I am not convinced in the slightest. " re: Yes I'm sure. I also diagnose hardware failure on a daily basis.

"That is entirely not relevant, unless you are suggesting contention from multiple mail clients might be causing confusion at the server level as to what is going on. " re:Yes and two programs work properly and without problems and only TB is a problem, but it is "not relevant" and nothing can be deduced from it. Really? Customers have different response times set in quite large intervals, except for this the IMAP protocol was created. I will not mention that it is the same when I start them in turns. But of course it is not important :)

"(...)Nadal jednak wydaje się, że masz narzędzia antyspamowe, które są najbardziej prawdopodobną przyczyną problemu.(...)" re: Anti-spam tools are: - on the postal host, but then such a message would not have arrived. - in the TB program - currently excluded - there are no more others

But if ... something works, it should go to the SPAM folder. The messages themselves that disappear and appear after reconfiguration in TB do not have such a designation. What's more, the last invisible message was invisible only to TB. On WebMail it was visible, in another client it was picked up right away. Applications arise right away, but yes I know ... this is irrelevant :)

I see no logs. Have you logged the imap operation without your anti virus or any add-ons running in Thunderbird so you can substantiate your statement that mail goes missing though Thunderbird's base actions? The link to do so it here. https://wiki.mozilla.org/MailNews:Logging re: please see a few posts above. The logs were taken exactly from the same link without ESET :)

"(...)When you have a log showing Thunderbird doing an unwarranted deletion (without any anti virus or anti spam toolbars installed or other add-ons running)(...)" re: it is not the removal of the message, but in some strange way not displaying it on the list with others. Because the message "physically" is on the server only not displayed by TB.

" Note that IMAP logs are verbose and quickly get very large. so you will have to identify the exact actions, not upload thousands of lines of log. No one will have time to read it." re: aha, You are asking for a logs, but we do not have time to diagnose them, to diagnose or exclude something, OKEJ :)

2 HAVE THIS PROBLEM

"This happens only to me? ...Apparently"
