Picked up a funny and couldn't find anything seemingly relevant on the forum.
Basically, I tried to add an alias (email@example.com) to an account (firstname.lastname@example.org) through the Admin UI. It told me that the alias already belonged to another account (email@example.com). I thought I'd better check that out and found that it was lying. There was an alias there of firstname.lastname@example.org. I removed that in case it was confused and tried again. This time it told me that there was an account with the name email@example.com. I thought, "no, there isn't", checked anyway & I was right. Started to think maybe there was a bug in the UI so I figured I'd have a go at the command line, check this out:
Did a zmpov gaa (just to be sure) and it's not there.
zimbra@mail:~> zmprov aaa firstname.lastname@example.org email@example.com
ERROR: account.ACCOUNT_EXISTS (account already exists: firstname.lastname@example.org)
zimbra@mail:~> zmprov da email@example.com
ERROR: account.NO_SUCH_ACCOUNT (no such account: firstname.lastname@example.org)
Anyone had this problem before?
