I have two mail accounts and in one I can delete messages fine, but the other I cannot. Any idea why this is?

Thanks

no idea but what are the differences in the accounts (provider, imap vs pop3, etc ....)

Both are imap, one is a google account and the other is a personal account on a cpanel server. The cpanel server is the one I cannot delete emails on.

It also seems only 1 folder has this behavior. I can delete mail in all other folders from this account, just not the inbox.

ps - voting for bugs may help

That did the trick. Just had to remove/add and then not check a server side subscriptions to avoid the bug. Also voted to make that not a duplicate of the other bug because it is doing something different.
