<font face="Arial">I am bringing this issue to both the Thunderbird
Support mailing list and Thunderbird planning in an effort to get
the widest possible input into the issue. Data loss becoming
apparent following compact has become pervasive in recent versions
and while there are no steps to reproduce it is an issue that is
severely affecting the perceived and in some cases real
reliability of Thunderbird as a data store. Roland has advised
that it is the number one support topic.<br>
<br>
Commencing around the Thunderbird 12 release (this is just a guess
as to version numbers) increased numbers of reports started
appearing in the GS support forum complaining about data loss
following compact. English version are not the only affected as
users continue to appear on GekoZone as well. (thanks Cameleon) I
have so far only been able to make observations and collect some
survey data from those affected. There is simply no recovering
from a compact data loss and I feel like an aid worker after a
disaster. People are quite attached to their emails<br>
<br>
The only common links appear to be AVG anti virus, while not
reported in every case it appears in a very significant number,
(in the region of 90%). The folder is Inbox. The other common
type item is the user often reports that they were advised via
dialog immediately before the incident that the<a
href="https://getsatisfaction.com/mozilla_messaging/topics/thunderbird_delieted_all_mail_in_my_inbox">
inbox was full </a>and they needed to compact the folder.<br>
<br>
My understanding is that there is no such thing as a full inbox
these days. To quote </font><a

face="Arial">Bienvenu </font></a><font face="Arial"><a
href="https://bugzilla.mozilla.org/show_bug.cgi?id=721925#c2"> </a>"In
TB 12, we got rid of the 4GB limit", as such a full inbox message
should not appear. That it does is obvious. If it is truly
relevant or a red herring I do not know.<br>
<br>
Is this a regression that has appeared from the work done in <a
href="https://bugzilla.mozilla.org/show_bug.cgi?id=402392#c96">Bug
402392</a> which landed in TB12, is this linked to the
regression in <a
href="https://bugzilla.mozilla.org/show_bug.cgi?id=750569">Bug
750569</a> I have no idea and need input from those that might
know.<br>
<br>
What I do know is Compacting is now Evil and whilst I have not
suffered from data loss and do not use AVG I think twice every
time that compact dialog appears. <br>
<br>
What I do know is that we need to stamp out these errant compact
issues and soon (<a
href="https://bugzilla.mozilla.org/show_bug.cgi?id=58308">maildir
where are you</a>). I have read much discussion about brand and
confidence in the etherpads from Warsaw, well I think in the
users mind their confidence in Thunderbird to store their mail is
currently shaky and getting worse..<br>
