Since I tried to set several mail accounts to use a shared inbox, none of the accounts retrieves mail, even if I reset them to use individual inboxes
These are POP3 accounts. One was set up and working OK, I then added two more and set all three to use a common inbox in Local Folders - where I had already moved everything from the account inbox. Since then, I don't receive any mail on any of the accounts, although I know from checking through a webmail client that there are new emails waiting. I changed the settings back to use the individual inboxes for each account, but the mail still isn't retrieved.

Update - I managed to get the email working again by deleting and re-creating all the accounts. I'm not going to try setting them to use a common inbox again though, unless someone can explain how to do that safely! Unified view isn't quite the same but will have to do for now.
I would advise doing changes in offline mode as this prevents you from getting new mail whilst in the process of configuring the accounts.
Info on Global Inbox
When you selected to use the 'Global Inbox (Local Folders)' option, did you also select : 'Include this server when getting new mail' ? Suggest you make sure it is selected. then click on OK
Did you then alter all the necessary Account Settings > Copies & Folders to look in correct place? Restart Thunderbird before going back to online mode to prevent any download before restarting.
