This is an update from the email provider:

"On Monday, 13/03/2023 we initiated a migration on our prodB environment. For 99% of our users the migration has been completed and you should expect a return to normal operating.

We have received reports of users describing issues with duplicated email messages on their IMAP clients. This is related to the means in which IMAP clients determine whether a message has already been downloaded locally. The quickest way to address this issue is to completely remove and re-add the email account on the mail client. This ensures that any incorrect caching information kept by the mail client is discarded, and presents a consistent view of mailbox contents."

On 13.03.23 there has been an issue with our email provider. The issue has been solved but we are aware that some email accounts are full because of that incident and we are in active contact with the email provider to further investigate. It is our priority to solve the issue.
