Thunderbird 115.6.1 (32-bit) on Win 10 and Win 11, local calendar, no email invites are sent to the listed Attendees. Correct email is entered on Calendar/Properties/Email and Notify attendees is ticked on New Event dialogue. Attendees are correctly entered under New Event/Invite Attendees. After clicking Save and Close, there is no Invitation email record in "Sent" emails and the Attendees do not receive email invitations. The event *is* saved in the originator's calendar.

The invites were correctly sent on the Win 10 PC up until TB version 113 (?), when they stopped working after the update (I think). Eventually email and calendar data were transferred to a fresh TB installation on a Win 11 PC, but the invites are still not sent.

The only difference that I can see between this non-email-invite-sending version of TB on a WIn 11 PC and another Win 10 PC where the invites are sent, is that "Troubleshooting Information/Force Email Scheduling" is set to true on the non-working version and is blank on the working one. Clues where to look next?

In the end I backed up the profile and exported all emails as EML files from the Win 10 PC. I then

1. Uninstalled TB from the Win 11 PC 2. Deleted the TB profile data from the Win 11 PC 3. Reinstalled TB onto Win 11 PC 4. Copied the calendar local.sqlite in the calendar-data subdirectory from the Win 10 PC to the Win 11 PC 5. Copied the ID from the prefs.js on the Win 10 PC and edited prefs.js on the Win 11 PC, changing the 7 occurrences of the ID in prefs.js. See

for a more detailed description.

2., 4. and 5. *must* be done while TB is not running.

I then restored the emails and address books (but nothing else) from the backed up profile of the Win 10 PC onto the Win 11 PC. The export and import of emails was a painful iterative operation since the exporting and importing of emails in 115.12.1 is buggy - only a (random?) subset of directories is correctly imported. Having EML files exported from the Win 10 PC allowed the manual recreation of subdirectories which were not exported/imported correctly.

Success! The Win 11 PC calendar now sends invites correctly.

It would be really good if the exporting and importing of TB data were functioning:

1. 115.12.1 TB calendar export/import is broken; see https://thunderbird.topicbox.com/groups/enterprise/T2c04aa4c32fb3256 as well as https://www.precedence.co.uk/wiki/Support-KB-Thunderbird/HomePage and https://forums.mozillazine.org/viewtopic.php?t=3110539 2. The email export/import transfers only random email subdirectories

and if the export/import functionality allowed selectable export of calendars, emails, address books and other data and not only an all-or-nothing lump.
