"That Bag is Full" (Can't send mails in-game)

Hello
As the title says, i'm currently unable to send items via mail to my banker toon. Said error message used to appear when you had too many emails waiting to be opened, which is not the case as i've cleared the mail of my toon completely for more like half an hour.
Tried deleting the cache folder but doesn't seem to work. Sending mails to "less busy" characters of mine DOES work.

Any help?

You can not send anything to a character that has 50 or more mails already in mailbox. Clean out the mailbox and you will be able to send to that character.

That's exactly what i did when i got the message. Cleared everything reloading UI, had zero pending mails. The message "That Bag Is Full" persisted for at least 45 minutes after i had everything clreared.
