> Seem like a pretty drastic limit of 1000 messages/folder. Does T-Online also limit the number of folders (mailboxes) you can have and the amount of storage in a folder? 

T-Online has a limit on the number of messages per, the number of folders and the storage space. This limit depends on the tariff booked. Because T-Online is the largest German Internet provider, many users have the associated free mailbox tariff with 1000 messages per folder.

> The "improved" quota should be visible on any tb client so maybe this will help?

This would be a great improvement.

> Does T-Online support imap MOVE or UIDPLUS capability? If imap MOVE is supported, any message deleted and "moved to trash" will actually be expunged from the source folder by the server. If move is not supported but UIDPLUS is supported, messages deleted and "moved to trash" will be "copied to trash" and then UID expunged by tb command from the source folder, so this effectively simulates MOVE.  But if neither MOVE or UIDPLUS is supported by the server, the deleted message will by copied to trash and left marked as \deleted in source folder and invisible with "move to trash" selected. If "just mark as deleted" is then selected, the invisible messages appear with the red X and strike-through. (You may need to record an IMAP:5 log to know the supported capabilities: https://wiki.mozilla.org/MailNews:Logging.)

I can't answer that for sure and I can't test it either because I don't have a T-Online account. I ask in the German support forum whether someone can test it and create an IMAP log.

> I'm not clear on how 5000 messages got into Trash and all marked as \deleted and invisible (or maybe just two?). Tb always move/copies to Trash and leaves the \deleted flag off so they are not invisible sitting in Trash. Then when you empty trash the messages are all marked \deleted and then the Trash folder is expunged, permanently deleting them all.

This is a good question that the user concerned will probably not be able to answer with certainty. However, the user had received a warning for 96 % quoata via IMAP in Thunderbird. In the webmail account, however, only about 25 % quota were given (because the invisible, deleted-marked ones were also not visible there). So the warning could not be understood. The user then tentatively deleted lots of emails (to my knowledge, via the "Move to trash" option). Maybe that's why there were almost 5000 deleted-marked mails in the trash, which were still not visible in both Thunderbird and Webmail. The result of this was that the quota was then at 100%. The trash could then not be compacted due to the two "defective" emails. These two messages have probably prevented compacting for 3 months.

> Reading again, not sure what you mean by "2 undeletable / uncompactable" in trash. Did tb cause this?

I don't know, what the problem of these 2 "defective" messages is. Invoking the compacting process leads to a neutral network connection error message. But these 2 messages can be moved to other folders. But they are still not completely deletable.

> Maybe I'm missing something, but you can just change the delete mode back to "just mark it as deleted" and you will see any invisible messages (marked as \deleted) with the red X and strike-through.

But first you have to get the idea to switch the option in Thunderbird and then discover the deleted marked messages. You can't expect that from most "normal" users. Thunderbird used the Account Assistant to guide many users to IMAP accounts. These users would probably have always set up POP accounts. I think we have to help these "naive" users now that they can use IMAP and not fall into traps. One of these common pitfalls is the server quota problem.

> But I think you are saying you want to see this always.

IMHO, this would be a good idea and I have no idea, why it would/could be bad.
