"Message store has reached its maximum size" error when an Office 365 user tries to delete an item in Outlook or Outlook Web App

PROBLEM

When a Microsoft Office 365 user tries to delete an item such as a calendar event in Outlook or Outlook Web App, the user experiences the following symptoms:
  • In Outlook, the user receives the following error message:
    The message store has reached its maximum size. To reduce the amount of data in this message store, select some items that you no longer need, permanently (Shift + Del) delete them.
  • In Outlook Web App, the user receives the following error message:
    The action couldn't be completed. An error occurred on the server.

CAUSE

This occurs if the items in the Recoverable Items folder of the user's mailbox have exceeded the default quota of 30 gigabytes (GB).

SOLUTION

Contact Microsoft Support to request an increase in the default recoverable item quota.

MORE INFORMATION

The Recoverable Items folder is not visible to the user. It contains mail items that have been soft-deleted.

An item is considered soft-deleted in the following cases:
  • A user deletes an item or empties all items from the Deleted Items folder.
  • A user presses Shift+Delete to delete an item from any other mailbox folder.
Users can use the Recover Deleted Items feature in Outlook or Outlook Web App to recover a deleted item.

For more information about deleted item recovery, see Recoverable Items folder.
