I suggest you contact the owl people. Normally you would right click the folder, select properties and then the repair button to remove corrupt index entries which is what this sounds like. But with OWL in the mix, you probably should be checking in with them.

Well, OWL does not have the faintest idea. They want me to provide a "how to replicate" description, which is not doable with such an issue.

All good, nobody know what could it be, or how to solve it.

Almost as good as microsoft.

Given you are interacting with Microsoft Software via OWL you may well have been more right than you know.

However as there is no screenshot, I really can not begin to guess.

Did you try my previous advice

Hey Matt, No I haven't, since you hinted that I should contact OWL.

And since they seem to be clueless about it, I've deleted the offending messages - although I'm sure I'll get some more, soon enough.

Having said that, here's the screenshot attached - it does not say much.

To recap, these non-messages appear in the 'deleted' folder, so a further delete does not move them anywhere, just deletes them for good - and it still works, I just get new ones after a while.

Edit: I've uploaded the screenshot...but it's not appearing. I'm a bit baffled. Re-uploading.

My guess is the size.... try using PNG for online forums.

But I see it now, When you have one, select it and press Ctrl+U and get the actual source of the entry. It might be informative.

If you post the source here as a reply, do it and nothing else in the post. I can "edit" your posts and see the original of what you post, if the forum makes a hash of the headers and any HTML.

I do wonder if we might be seeing another instance of something I had with Hotmail some years ago. Instead of deleting message as Thunderbird requested, Microsoft decided the would move them to a POP folder under the deleted, but were so slow about it that the mail actually downloaded multiple times. Perhaps this is some sort of timing issue with other devices you get mail on. Perhaps emptying the trash on your phone or the like.

There is always the error console, but I am rather loath to suggest it as this is not something that can be predicted. The console is full of all sorts of junk errors. Mostly from HTML. So really finding error related to this in it's output may be like finding the proverbial needle. But perhaps open it (Ctrl+Shift+J) and clear it. If you are at your machine when the phony messages appear the content of the error console from that time may be helpful. (Errors from OWL especially so.)

These errors are of no significance, despite them being the majority of entries in my error console. I assume that are the result of something the Mozilla platform has done.

Thanks for the response.

Definitely not a sync phone sync issue, I do not use it for emailing - the only one to sync is the desktop.

I'll keep an eye on it and if a new one pops up I'll try and check the source. I've deleted these I had last.

Emptied the console, too, thanks.

Ok, took it a while but here I have another one again.

This one (going by the source) looks like a cancelled vcalendar event notification from microsoft, I can identify the event, I've cancelled it. (weird that I get a notification of what I've done, but whatever)

So this might be a tad different (I did not have a 100 of these before).

But shows up the same; unread, deleted, blank. No subject, no sender, no recipient.
