Dear Tutanota user,
on Thursday, 29th of June, some previously deleted emails have accidentally been restored during maintenance of our servers. This only applies to emails deleted between the 12th and 25th of June. Please check whether there are emails in your mailbox that you'd rather have deleted. Affected users were partly not able to access their mailbox folders.
Background info
Emails in our database are replicated several times to make sure that no data is being lost. We have activated one of our database servers again which had been down for maintenance for a while. Unfortunately that server has executed some write requests that could not be completed before, thus some later deleted emails were restored. We have analyzed this bad behavior and made sure it will not happen again. We could only identify a part of those emails and remove them from the database. For transparency reasons it is our obligation to inform every Tutanota user about this. By informing you directly via email, you have a chance to spot remaining restored emails and delete them. We apologize for this issue.
Best wishes, your Tutanota Team
