Evolution sync error IMAP : "Too many user flags in mailbox "


Evolution can’t sync IMAP box anymore from laposte.net (french email provider)
Error is :
Impossible d’actualiser le dossier « La Poste : INBOX ».
L’erreur signalée était « Erreur lors de la synchronisation des modifications: Too many user flags in mailbox ».

in english : “unable to sync INBOX folder. Error was : Too many user flags in mailbox”.

Any idea?


Hi and welcome. This error message does not exist in the Evolution codebase. It is a message that your mail server sends, so you need to contact whoever maintains your mail server. Evolution only displays what the mail server told Evolution.

I removed the subfolder you mentioned (only the one for this mailbox). Evolution refreshed the mailbox after restarting but the message reappeared.

I send a message to Laposte.net admins, but I’m affraid they are less fast a you to answear… :wink:


PS : I’m currently using Evolution on a Debian 12 laptop (Dell Inspiron 1525) on a FXCE4 desktop
