Thunderbird Portable

Hello,
I am using thunderbird portable for years and it worked fine until yesterday.
I got a new PC, Dell Latitude 5570, Win7 Pro, and wanted to get my mail using the stick.
But neither receiving nor sending worked.
All mailboxes are pop3.
After changing the port and authentication for the smtp server I could at least send messages.
Receiving does not work though I tried different parameters. I can access the mailbox via webmail.
The provider says everything is ok with those mailboxes.

Hi all,

I am a long-time Thunderbird user (normal version, not portable version), and have always kept my Thunderbird (TB) profile segregated on a dedicated data drive vs. on the regular system drive under my Windows user profile. For example, whereas a default TB install would put one's profile under "C:\Documents and Settings\[user]\Application Data\Thunderbird\Profiles\default.???\", I have always pointed it to "D:\My E-mail Profile\" where I've kept my profile for easy backup.

Heya,

They are not saved correctly (virtualFolders.cat is not being updated, no new folder is being created under Mail Folders) and they just don't work..

Thank you!

I used "Edit As New" (Sent folder) in Thunderbird 45.4.0 and the opened messages were in HTML format.

But now with portable Thunderbird the messages open as text, links are not clickable anymore, for example.

I was using the same settings I used before and also made changes to force HTML format, but it made no difference.

It may be somewhere in the blurb, but I've failed to find anything to tell me if I can use the Thunderbird Portable app on both PC (laptop & netbook) and Android (Tablet & Phone), in which case I'll use an OTG Flash Drive for my download. Anyone know, please?

I have the Lighting calendar add-on in my Thunderbird portable. In the past, when I received an email that was an invitation to an event, I would click the Accept button, and the event would populate the appropriate day on my Lightning calendar. However, this past week, when I accepted an event, instead of populating Lightning, it populate the calendar provided by my email service, Outlook on the web (specifically, Office 365 Business Essentials).

for some reason the download always fails.
I manually downloaded the paf (because I gave up on the automatic update after a week of trying) from: https://sourceforge.net/projects/portableapps/files/Mozilla%20Thunderbir...
and i'm getting an error that it can not be executed.
i'm using windows 10 64bit

I think it was an update around mid August that broke my current TB Portable copy on an external HDD.
When I logged in it tried to start everything off as a full newbie - no existing profile, emails, etc.
After some research I tried starting the app with a "-profile but that didn't work.

Greetings.
I plan to migrate from Outlook Express, Thunderbird is one of the candidates.
My computer is old, OS XP, and I format it with frequency, then a portable software would be very convenient.
The problem is that I just download the portable Thunderbird here in portableapps and installed, clean program is consuming around 160MB, even after disabled Lightning and offline mode.
When I run it, open two applications in the task manager, thunderbird.exe (~ 160MB) and ThunderbirdPortable.exe (~ 6MB).

Subject: From where besides Default Programs, and besides under Options, Advanced, Config Editor, is ThunderbirdPortable finding FirefoxPortable?
This is about Thunderbird 45.3.0, not Firefox. Just so you know, I asked this first of Mozilla and was told in full: "Thunderbird passes the hyperlink to the operating system to the default handler (Browser) anything else is portable apps magic." So here I am at the magical PortableApps.
