Cannot allocate space error in Lotus Notes

Lotus Notes user hitting cannot allocate space errors on their mail file, new mail bouncing and the client complaining on open.

What is running out of space when the disk itself has plenty?

The space running out is the database's own allowance rather than the disk: Notes mail files carry a size quota set by the Domino administrator, and the NSF hitting its quota produces exactly this error family while gigabytes sit free around it. The relief sequence:

1

Confirm the diagnosis: in the Notes client the database properties, File, Application or Database, Properties per version, show the file's size against its quota and warning threshold on the info tab. Size at or above quota confirms it, and the same properties on a colleague's healthy file shows what normal looks like.

2

Reclaim space inside the allowance first: empty the mail file's trash which Notes counts against quota, delete the obvious heavyweights found by sorting the All Documents view by size, calendar ghosts and sent attachments being the usual mass, then compact so the file actually shrinks, File, Application, Properties, the compact button on the info tab or the admin runs load compact mailfile.nsf -c server side for the thorough version.

3

Archive the history rather than fighting the quota forever: Notes archiving, Actions, Archive, Settings, moves older mail into an archive NSF outside the quota per the policy's criteria, the sustainable arrangement for mail heavy users, with the archive file's location and backup deserving one deliberate decision while setting it up.

4

Escalate the quota when legitimacy demands: the administrator raises it in the person's directory document, the request landing better when accompanied by evidence of the cleanup and archiving already done, the sequence above being that evidence.

Era note attached as these threads deserve: cannot allocate space on a Notes file is frequently the moment organizations discover how mail heavy their Notes estate grew, and the archive NSFs created during relief become tomorrow's migration inventory, the conversion machinery covered in this forum's NSF threads reading them identically to mail files whenever that day arrives.

Quota confirmed at the ceiling exactly as diagnosed. Trash and three ancient attachment monsters freed a quarter, compact made it real and archiving is configured for everything past two years. The user sends mail again and the admin got the polite evidence backed request.
