Thunderbird Portable

After updating from 31.7 to 38.2 Thunderbird Portable, installed locally on a HD with Win7 Pro, I could not send mail through an external server. I was able to receive mail through the same server. When I downgraded back to 31.7, I was again able to send and receive mail.

On trying to send mail, I got an Alert box that said:
An error occurred while sending mail. The mail server responded: Administrative Prohibition. Please check the message and try again.

It would be really really nice if you could add printscreens to a topic. Printscreens do say much more than words can describe...

I am having a lot of folders and with the sendfilter all the mails ( of my clients do go to the specific folders immediatly.
As i am receiving a lot of mails on a day, it's so nice i can see which mails are completely new, because they are BOLD+BLUE COLORED.

The download link on https://portableapps.com/apps/internet/thunderbird_portable that points to https://downloads.sourceforge.net/portableapps/ThunderbirdPortable_38.1.... doesn't seem to go anywhere. I initially thought it was due to script blocking addons in my FF install so I tried it in Google Chrome which doesn't run with any addons and it behaved the same.

I am asking how to up date Thunderbird Portable and all the free platform. I haven't find a direc "clik" here to update

I have been using TBportable for 8 months now on both a French XP SP3 32bits and a English W8.1 32bits without problems.
Then I tried to use it on my new French W7 64bits computer and a French W8.1 64bits one and I have problems: Some of the folders containing mails do not show on the left side directory tree of the program. The folders and mails are always on the USB stick but they simply do not appear. When I run again TB portable on one of my 32bits systems they re-appear...
The same TB portables ran on 2 different English W7 64bits computers without problem ....!!

Hi,

I am put ThunderbirdPortable into D:\Progs\Thunderbird
All my files will be saved in Data/profile, Data/plugins, Data/setting folders now.

How i can replace folder for all settings/profile/mails/plugins to other disk (C:, F: ... not D!).
in Source/ThunderbirdPortable.ini i can use onle *relative* path. Why not absolute path?
