Hi all,


After thoroughly searching this database, I could not locate an answer to the issue I am facing, although there seem to have been several similar cases.

My former university has recently decided to delete alumni email accounts, so I am using Thunderbird for email transferring from university to GMail (added both accounts to Thunderbird and then began copying emails and folders). Transfer is slow, depending on the server capabilities etc., but I am going folder by folder and so far it has been fine. I began the transfers a week ago.

Last night I noticed my Thunderbird inbox for my school is not showing anymore. The profile folder is only showing one file (.msf) for Inbox, instead of what should be, in my understanding, two files.

Thunderbird is still communicating well with the university email server because I made a folder rearrangement on the university webmail service (outlook.com) and it showed on Thunderbird. In addition, all my Inbox emails appear fine on the university webmail service (outlook.com).

Any ideas? This is obviously important and urgent.


Thank you in advance.

Things I have tried and are not working: Thunderbird safe mode Refreshing by right-clicking the account and selecting "get mail" Other advice found on this site or elsewhere online

Please note Thunderbird updated itself last night, which likely coincides with the beginning of the issue above. Might this be a bug of the new update (147.0-20260108190847)?

Is this an Exchange based account, or imap?

Developers are considering the possibilities.

> Last night I noticed my Thunderbird inbox for my school is not showing anymore. The profile folder is only showing one file (.msf) for Inbox, instead of what should be, in my understanding, two files.

Were you using version 146 at the time?

Okay, thanks. If that's the case, what's the resolution?

When I began the transfer, I was using the prior version (not sure which, 146?). I noticed the inbox disappearance yesterday, and I think it might have happened after Thunderbird automatically updated to the latest version (147).

Please obtain a log. If it shows private information, rather than post here email it to edicharry at thunderbird.net

General logging instructions at https://wiki.mozilla.org/MailNews:Logging. See #29. Use environment variable MOZ_LOG=ews_xpcom::*:4

Another thing that would help us triage this is to know whether or not the inbox shows up in a fresh profile. You can start Thunderbird with the `-profile` argument followed by a path to a new folder to get a fresh profile. Then you'd need to set up the account again. Starting Thunderbird later without the -profile argument (or from a menu item or desktop shortcut) would just use your normal profile, so trying this wouldn't affect your current set up.

Sorry, could you be more specific on the logging? I am not quite sure I understand how to do this...

If you set the environment variable MOZ_LOG to "ews_xpcom::*:5" and set the environment variable MOZ_LOG_FILE to a path to a file on your system, then Thunderbird will write a detailed log file to the file you specify in MOZ_LOG_FILE. Instructions on how to set those variables for each OS are in the "Environment Variables to set" section of https://wiki.mozilla.org/MailNews:Logging .

As a separate test, if you can, it would help to test a new profile as I mentioned in my previous post.

Sorry but I am still confused...

Are you giving me instructions for a command prompt or for Windows? The wiki page is describing creating a batch file. In addition, your instruction '"You can start Thunderbird with the `-profile` argument followed by a path to a new folder to get a fresh profile. "' is not clear to me. I just open Thunderbird on Windows and have no clue how to start Thunderbird with a "profile argument". I am a very new user of the program and am having a very hard time following your instructions...

If you could offer more detailed step-by-step guidance, I'd be grateful. If not, I will need some time to dig into this on my own, and still have tremendous doubts I will achieve anything...

In addition, there seems to be some discrepancy, see below.

From the wiki page... Gecko logging uses module names. It is the classic (old) method of getting log data. Gecko logging may be enabled via preferences (not discussed in this document), or command line, which is discussed below. Please provide instructions, if possible, to get this done on Windows, through Thunderbird menus, without using a command line.

Okay, so I think I finally understand what you probably mean. I need to create a batch file named "create_log.bat" and run it. But which of the following texts is the one to use for the batch file?


set MOZ_LOG=ews_xpcom::*:5,timestamp set MOZ_LOG_FILE=%USERPROFILE%\Desktop\log_file "%ProgramFiles%\Mozilla Thunderbird\thunderbird.exe"

set MOZ_LOG=ews_xpcom::*:5 set MOZ_LOG_FILE=%USERPROFILE%\Desktop\log_file "%ProgramFiles%\Mozilla Thunderbird\thunderbird.exe"

set MOZ_LOG=ews_xpcom::*:4,timestamp set MOZ_LOG_FILE=%USERPROFILE%\Desktop\log_file "%ProgramFiles%\Mozilla Thunderbird\thunderbird.exe"

set MOZ_LOG=ews_xpcom::*:4 set MOZ_LOG_FILE=%USERPROFILE%\Desktop\log_file "%ProgramFiles%\Mozilla Thunderbird\thunderbird.exe"

The discrepancy doesn't matter in this case, as it just specifies the log level and there's nothing in level 5 that you wouldn't see in level 4. You can use level 5. Here are instructions on how to do this from the UI:

1. Go to the hamburger menu in the top right corner of the screen. 2. Choose Settings... 3. In the General section, scroll to the bottom and press the Config Editor... button on the bottom right. 4. Enter "logging.config.LOG_FILE". You will see options below the text entry box to create a value as a boolean, number, or string. Select String and press the + button on the right. You'll then see a text box with the ability to enter text. Enter a path to a new file somewhere on your system and press the check mark on the right to save. 5. In the top text box, enter "logging.ews_xpcom::*". You will again be presented with the option to create a new value. Choose a number value this time, enter 5 for the value, and press the check mark on the right to save.

Once you've done that, go back to the main UI and trigger an update (you can do this by pressing the cloud icon with a down arrow in the top left of the folder tree view). After you do that, in the file you entered for the logging.config.LOG_FILE value, you should have lots of content describing what Thunderbird did. Look for errors in that log, or if you want you can email it to me at the email address Wayne mentioned above.

You can ignore my earlier suggestion to try a fresh profile. That can only be done from the command line.

Does the file path have to be provided as "%USERPROFILE%\Desktop\log_file"

or as "C:\Users\...\Desktop\thndrbrdlog.txt"

?

And with quotation marks or not?

The menu is not giving the option of browsing for a path and one would need to know the syntax rules before entering anything there.

Full path and no quotes.

I have done all the above and the file appears on the desktop but it is empty.
