All non-marked messages unread

[Eric S Fraga]

I have a very strange problem. All messages from a certain folder that
where not marked became unread. This where around 30.000 messages. I
used ‘c’ (gnus-summary-catchup-and-exit) to mark them again as read.
When entering the group again disaster has struck: there where only
4.000 messages (about 13%) left. All the others had disappeared.
What has happened here?

I have no idea but I have had the same thing happen (in terms of
non-marked articles being made unread) 2 or 3 times in the past 2 years,
but only with IMAP to an MS Exchange Server and never with other IMAP
servers (just in an attempt to add a data point). Incredibly
annoying.

In my case, I did not lose anything however but maybe this is due to
your expiry settings?

With two gnusen open on the same group, the last one to quit the group
will win. Could that be what was happening...?

not in my case; maybe relevant for the OP. I never have more than one
gnus running at any time.

I personally think there's a problem (well, many) with MS Exchange... I
wish I didn't have to use it but all attempts at local copies with
synchronisation (isync, offlineimap) have failed due to strange errors
with the server.

Anyway, not a problem. I've learned to live with this and I have more
serious issues to address than the shortcomings of MS Exchange... I
simply wanted to add a datat point for the OP's benefit.

thanks,
eric

If you don't need to access your email from other clients, I can
recommend downloading the emails from MS Exchange, using IMAP as a fancy
POP3, and storing them locally (say, in nnml). That has worked without
problem for me the past 7+ years.


Best regards,

Adam, taking this even more off topic, and probably repeating myself...

Yes, maybe this could be the ay to go. I do access my mail from various
other devices but less so all the time as my portable linux devices
become more portable and more powerful....

thanks.
