The index of folder '%2 'seems to be out of date. To prevent message corruption the index will be regenerated. As a result deleted messages might reappear and status flags might be lost. Please read the corresponding entry in the FAQ section of the manual of KMail for information about how to prevent this problem from happening again.
De yndeks fan map '% 2' is net aktueel. Om berjochtbeskeadiging te foarkommen sil de yndeks opnij oanmakke. It kin foarkomme dat al fuortsmiten berjochten wer ferkine, en tastânmarkearrings ferlern gean. Lês de FAQ yn de hânlieding fan KMail troch foar ynformaasje oer hoe jo dizze swierrichheid foarkomme kinne.
