Known issues

Below is a list of known Alcion issues and limitations:

  • Alcion supports Exchange (email, calendars, contacts), OneDrive (files), SharePoint (Document Libraries), and Teams (Chats). Additional data types and services will be added in subsequent releases.

  • Backups of Exchange email may not include changes to the read status of an email if no other changes to the email have been made since the previous backup.

  • Restores of nested attachments within Exchange Mail or Calendars aren't yet supported.

  • Folders and Calendars containing zero items or sub-folders aren't included in the backup.

  • Provides no guarantees about whether data moved, added, or deleted in M365 while a backup is being created will be included in the running backup. Future backups run when the data isn't modified will include the data.
