This article explains which emails are delivered by the Continuity Service to your mail server.
Which emails are delivered?
Basically, all emails are delivered to your mail server or user as soon as your mail server is reachable again. Emails located in the folders Inbox and Sent are removed from the Webmailer after successful delivery.
Which emails are not considered?
Emails located in folders other than those mentioned above are not delivered to the destination server. This also applies if the server becomes reachable again at a later time.
For example, if you move an email to the folders Project A or Important, the emails contained there will not be delivered to your mail server and will remain accessible in the Webmailer.
