<helpdesk_mailbox_email>" -FolderScope RecoverableItems | Format-Table Name, FolderPath, ItemsInFolder, FolderAndSubfolderSize
Result:
Recoverable Items folder is exceeded the default 30GB limit If the folder is out of storage quota, mails can't be deleted by SDP and the processed mails stays in the Inbox folder. So, new mails aren't fetched into SDP and user can find mails getting accumulated in the Inbox due to this.
How technicians are notified on this?
Once the recoverable folder is out of quota, technicians will be notified as follows
1. On navigating to Incoming settings page, the below error message will be displayed.
2. SDAdmins of the portal will be notified through Technician Space (Bell notification)
Technician space and email notification will be repeated every 30 mins till user clears the Recoverable Items folder of the configured mailbox.
How to resolve this ?
Since, this is a limitation in the configured mailbox, the Technician should reach their internal mail team once they receive this notification. Their internal team can help them resolve this. Till then, mail fetching schedule in SDP will not be stopped. Once the folder is freed, mails will automatically be fetched by SDP.
