What means the error message: ”MAPI-Error: MAPI_E_NOT_ENOUGH_DISK”?

The reason for the error message below is, that there is not enough space on your hard drive. Please make more space on your hard drive available. After solving this problem, I would recommend you, to leave the SYNCING.NET "Outlook Group" with this computer and join it again. If it is the manager of the SYNCING.NET "Outlook Group" you should delete the group and create it again.

More reasons for this message:

  1. The hard drive is formatted in FAT32. Files cannot be larger than 4GB.
  2. Your pst-file is corrupt and you should repair the pst with scanpst from Microsoft. Find more.
