This issue occurs for one of the following two reasons

1. This issue can occur if the SMTP holding folder threshold has been reached or if the SMTP Holding folder volume does not have enough free space available (for example an 8 TB volume with 10% default threshold would be around 818 GB's).
2. Windows explorer reports the wrong information about the available space on the SMTP holding folder

Change the threshold that is being monitored or move the SMTP holding folder.  

Change the monitoring threshold

Go to EV Site > Properties > Monitoring Tab.
Set the Space on SMTP holding folder volume - error setting to the required percentage and restart the Enterprise Vault Admin Service.  

Move the SMTP holding folder

If the free disk space is low for the volume then it is recommended that the SMTP holding folder be moved to another location or more space be added to the current drive. To move the folder use the following process - 

1. Stop the SMTP archiving task. 
2. Go to the Holding Folder tab on the Properties of the SMTP archiving task. 
3. Click on Help for guidelines on moving the folder to a new location.
