How do I make sure I have all headers in a group?
How do I make sure I have all headers in a group?
I know I have most of the headers, but I want to make sure I start off with all without having to start from scratch. I try open&rescan which doesn't seem to do it then I tried catch up with now leaves some headers that I did have complete as partials (which is not cool ) this is a large group, so I am hoping there is a good way to get all the headers without having to start over.

if you need it rarely in the workspace (view menu->workspace to toggle), the leftmost newsgroups pane, right click the group then invoke advanced->reset header ranges.
or you can configure rescan in edit menu->properties->general, rescan, rescan only last x headers, if you make the field empty it will rescan all headers. if you also check "only redownload" (if you don't it may take a long time until you see any change and if the operation is interrupted by the server it will fail and will have start over again without any change) the result will be exactly the same as if you invoked reset header ranges above, but with the rescan it will be permanent behaviour when you invoke rescan and reset header ranges is one time.
if newsgroup is large though, maybe better not to rescan all headers, normally servers don't return headers out of order, so you can set some relatively small value to be sure.
if you delete headers (or they are set to be deleted after saving attachments which is default), you can still see deleted headers when you check "del" in the quick filter bar (view menu->quick filter bar), you don't need rescan headers. you can purge headers (so they won't appear when you check "del"), but it is not really needed, maybe when it is spam of a lot of single messages purging will have positive effect on memory usage.

None of this seemed to work in fact after a rescan almost all the headers went away even though the database in explorer was wtill almost 3 gigs. So I just deleted the group and am starting again looks like it will take about a day and a half. Is there anyway to speed up getting headers this group has just over 90 million.
Thanks!

i think you missed something. did you try just to reset header ranges as i described and not to invoke rescan option alltogether?
if you have problem with rescan - be sure to have "Only redownload (don't optimize)" in properties->general->rescan checked, it means the server has troubles performing xhdr command e.g. stops sending headers prematurely or don't send them all with the command still indicating success in the end so UE relies on its wrong results.
if "only redownload" checked - rescan will have the same effect as resetting header ranges, UE just redownloads all headers without touching existing headers.
to have header download faster - you need to use a server with header compression working within SSL (built in) or xzver (nntp native option), e.g. most highwinds company servers (ngroups, UNS, newshosting) or astraweb, usually speed will be 5 times faster, but even with non-compressed headers if header download speed is too slow it is a server problem.
deleting newsgroup doesn't make any sense, if you reset header ranges UE just downloads headers like the newsgroup is newly created, existing headers cannot influence it in any way, just ensure in task manager->headers it really downloads those headers in uniform manner, if you see the red question mark tab to the right of the headers tab it means there is a problem with the server, you can see the error there.
sometimes servers may time out, then when you redownload headers again UE will resume from the point when server interrupted the connection but only if you reset header range directly, in the case of rescan it will start all over again, so maybe you better reset header range instead of rescan, if you are using a troublesome server and you see header tasks interrupted.
as to help here is the help, with normally working servers usage pattern usually simple and as to advanced options there is forum in addition to what you can find on the website, as to malfunctioning servers there are always alternatives.
