Since yesterday evening, I noticed that my webmail box got duplicated. All the folders appear twice, and emails are also duplicate (new arrivals too). The two mailboxes are listed on the menu with exactly the same email address.
On Thunderbird it is still a single mailbox though.
Would you have an idea what went wrong? Could it be related to the fact that I have 1 alias?
NB: for one of the two mailboxes I can click “delete account” but I am not sure of the consequence since they seem to be the same…
