Thunderbird Portable

One or more unexpected DLL files were found in the same directory as K:\PortableApps\ThunderbirdPortable\ThunderbirdPortable.exe. This could be an indication of a covert attempt to hijack the application using DLL injection. Please check the application before using it.
I have Kaspersky and Malware scanned the directory with a negative result.
What do I do next since I cannot load Thunderrbird.

or is there a previous version to download,

Hello,

actually I use the latest version ThunderbirdPortable_45.5.1_English.paf.exe. For the "normal" TB, the version 45.6.0 is available.

Can I use the build-in-update-function to update the PortableTB to 45.6.0 or I have to wait for ThunderbirdPortable_45.6.0_English.paf.exe?

I'm not sure, if the instructions shown here https://portableapps.com/support/thunderbird_portable#upgrading are still up to date?

happy computing

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).
