I have been grouping my mails in threads on hotmail for the first time, as I recently found out how to do so. But it seems there must be a limit on capacity, as I can no longer open the thread I now have that has 38 mails, while I can open the shorter ones. Is this the case? If so, how do I see the mail I cannot open? Can I revert to not grouping the mails, so they get split up into separate mails again? And if so, how. I can't figure out how I did it in the first place now.
