Thunderbird Portable

after long time, I am againg trying to set up Thunderbird on a usb stick.
Installed OK, but now I would like to paste there the profile from my desktop version
where exactly should I put the profile in?

I got used to TB portable asking to "confirm security exception" at location imap.mail.de:993 or imap.web.de:993. Regular installed Windows10 TB did never ask this nor does TB 115.
When I click "Get Certificate" this hangs for ever.
My E-Mail service provider suggests imap.mail.de:993 for TB. No special hint for TB portable.
I installed same TB 115.4.1 on Windows10. This does not ask for adding security exception AND works fine.

Available on the builds site 24 Oct, but rolled out slowly, so some users won't get it until 25 Oct.

My Portable Apps edition of Thunderbird Portable continues to update through the internal updater without any issues. Thank you, John T.

Since the new version 115 was introduced, my calendar and event data have disappeared several times and had to be restored from backup.
Has anyone else noticed this behavior?

115.2.3 became available this afternoon. If you have automatic updates turned off, you'll have to Check for Updates and accept the update (if desired). I see no problems in it, and the release notes report some very good fixes. If you have the Portable Apps app, you'll get 115.2.3.

Updated TB 08/Sep via the 26.1 platform o Windows 10 but TB 115.2.0 calendar now insists that event times are 2 hours later than they had originally been set: a previously set 12:00 appointment is now being displayed as a 14:00 appointment.

It makes no difference if I continue to use the system timezone or set it manually before re-starting TB.

Well, as we wait for the devs to figure out how to do auto-updates from 102.x to 115+.x, they've released a new version, contrary to what they said a while back:

From Thunderbird.net, 02 August 2023;
"Thunderbird 102.14.0, scheduled for release on July 30, 2023, is the final release of Thunderbird 102."
Users of Thunderbird 102.13 went to 102.14 running if they accepted the update.

Now, today, 30 August 2023, this:
Thunderbird 102.15.0, is the final release of Thunderbird 102.

Recently used Starlink connection on a trip, I could only send on first registered Spectrum (@twc.com) email address, not on the secondary twc.com email address. When got home and connected to my Spectrum ISP, could send again on both addresses for few weeks.
Last week reverted to AUP#Out-1500 msg when sending on second email. Spectrum 'tech' no help. Using TB 3.1 since 2012 with no issues. Not a mobile user so have not wanted, nor needed, to upgrade.

I installed TBird 116 Test a few days ago, and it updated successfully through a first 117 version to the current 117.0b3. But today I noticed that if I double-click a message in my Archives folder (in Local Folders), a Composition (Write) window opens, instead of a reading tab or window. This happens on both my office desktops, both Windows 11 Pro 22h2 2134, with Thunderbird Beta Test installed to my programs & data drive, not on my C:\ drive on either PC.
