MAPI restore fails with insufficient disk space error

This article applies to:

  • OS: Windows
  • Product edition: inSync Cloud and On-Premise

Problem description

In a scenario where email backup is optimized for efficiency from the inSync profile, the restore of the Outlook folder (.PST) of 32 GB initiates normally but fails. The restored PST file size is not 32 GB and the Restore status alert message states:
Outlook mailbox restore was done with errors.

Thus, the MAPI restore fails with the error:
There is insufficient disk space to complete.

Cause

When the backup is optimized for efficiency from the backup profile, PST files are backed up and restored using MAPI protocol. To perform a restore, inSync Client and Outlook need to be present and configured on the tare device.  Regardless of the restore location of the PST file, a MAPI restore automatically attaches the PST file to the mailbox of the user. If the total size of the attached PST file exceeds the default mailbox size, the restore fails.

Traceback

The following traceback is saved to C:\Programdata\Druva\inSync4\users\user\logs\inSyncSClient.log:

Resolution

Either remove the existing attached PST files or contact the email administrator to increase the size of the user's mailbox.
