I had previously named my subfolders with a non-alpha numeric character at the start (# or *) so that they came to the top of the list of subfolders.
Since changes to BT email a while ago i can't now access any of those subfolders - very irritating - any suggestions? (renaming them doesn't work btw - tried and failed that).
Solved! Go to Solution.
This was reported previously and the following reply was posted by the moderators.
Do you access your email using an email client/app on a mobile device. If so try changing the folder's name from within the email client/app. This should then synchronise with the BTMail servers and change it on webmail when you log on via browser.
If that doesn't work call BT 0800.800.150 and and asking for the email team and report the problem to them. They should be able to remove the illegal characters from your folders names.
See this thread.
