Thunderbird Community Forum

I have three PCs running Windows 10 and one running Windows 11. All of them have Mozilla Thunderbird updated to version 148.0 (64-bit). For the past few months (I think it started with version 146.0), every time we send an email, the "Sending a message..." window appears and takes between 15 and 20 seconds to complete. We've tried many things, such as disabling the firewall and antivirus, but nothing has improved the situation. Previously, any message would send in less than 3 seconds.

QUISIERA SABER PORQUE EL PROGRAMA DE LA APLICACION MOZILLA NO RESPONDE NORMALMENTE CUANDO INTENTO ABRIR LA BANDEJA DE CORREOS Y PARA DESCARGAR LOS ADJUNTOS Y NO PUEDO TRASFERERIR CORREOS A OTRA BANDEJA DE ENTRADA

Hi.

Every and each time I try to move any message to my local folders, or make any change on it, I get that error message. I can create new folders inside my Local Folders (for instance, a Test folder) and I can still access the messages stored there, but I can not make any further change.

I have tried these things so far:

1 - Check that I have enough space on the partition. 2 - Check the access privileges (I have set them to Total Control to all users). 3 - Compact all mail folders. 4 - Repair all mail folders. 5 - Rename the Local Folders to "Local Folders.old" and create a new one. 6 - Place the local folders in a different drive. 7 - Recreate the profile, either by copying the files manually and by importing them. 8 - Delete all local folders' .msf files (to rebuild indexes) 9 - Uninstall and reinstall Thunderbird from scratch to the last version - 142.0 (64-bit) 10 - Revert the last W10 system update. 11 - Check the antivirus configuration. 12 - Recover an old backup of my Mail folder (done when there was no error). 13 - Delete the entire disk data partition, reformat and recover it. 14 - Run Thunderbird in safe mode. 15 - Run Thunderbird as an administrator (as suggested by Gerardo below)

The error persists and I have run out of ideas.

Could someone help me, please? At my local folders I have years of messages that I still browse, and I use them as a local archive.

Thank you very much in advance.

Iskandar.

Buenos días:

Me sale el siguiente error compactando: La carpeta "bandeja de entrada en ..." no se pudo compactar porque falló la escritura en la carpeta. Compruebe que tiene suficiente espacio en disco y privilegios de escritura en el directorio, y vuelva a intentarlo.

- Tengo sitio en el disco y soy administrador del pc - ya probé a reparar la carpeta

¿Alguna idea?

Since the latest update to Windows 10 Pro and Thunderbird, this annoying Microsoft window keeps popping up, and I have to put it in the background, otherwise I can't even read my emails.

Thunderbird 128.7.1esr (64-bit) on MBP M4 Max 128GB with updated MAC OS 15.3.1 (24D70) For 3/4 days it is excessively slow, even stopping the rendering of letters when writing an email. I have Compacted the folder and even repaired it, restarted the MAC, deleted the SPAM but nothing, the behavior is desperate. It is practically impossible to work... so much so that I am considering another manager if I can't solve it and I really like THB

Hi,

When I'm trying to open en eml file from the windows explorer, it takes a very long time to open, aroun 2 min. This behaviour has started today and I'm not sure whether has to do with last beta version recently updated.

Any help?

Thank you, Best regards
