FIX: Dragging and dropping Outlook messages in quick succession results in file lock message



ID: ZTN4412

This Zetadocs technical note applies to:

  • Zetadocs for NAV version 7
  • Zetadocs Express version 7
  • Outlook 2010 and 2013


When dragging and dropping Outlook messages in quick succession into the Zetadocs factbox, users may intermittently experience the following error message:

In the ZetadocsCaptureAddin.log file, a log line similar to the below is seen:


Zetadocs.Exceptions.BaseException: The process cannot access the file 'C:\Users\equisys\AppData\Local\Temp\ad3acb46-b917-419b-88f4-718f01c9d72b\test.msg' because it is being used by another process. ---> System.IO.IOException: The process cannot access the file 'C:\Users\equisys\AppData\Local\Temp\ad3acb46-b917-419b-88f4-718f01c9d72b\test.msg' because it is being used by another process.

When this issue occurs, subsequent drag drops may not work until the Navision client is restarted.


This was due to a timing issue between fetching metadata information from the Outlook file, and archiving of the file. Outlook locks the message file when fetching the metadata and, in some instances, the lock is not released before Zetadocs attempts to archive the message.


This issue has been resolved in the April update rollup (7.0.392) of Zetadocs for NAV, available for download here.


This behaviour was corrected in the update detailed above. Zetadocs Express will have this behaviour corrected in the next major update.
