Log files

CodeTwo Office 365 Migration generates various diagnostic data for all its components. All this data is kept together within the software's subfolder in the %ProgramData% folder along with some configuration and statistics files.

Sending logs to CodeTwo Support

If you ever experience technical difficulties with CodeTwo Office 365 Migration and CodeTwo Customer Support assistance is required, you will most likely be asked to provide all your log files. To do that:

  1. On the program's Dashboard tab, click Log files in the Help box (Fig. 1.). This will open the %ProgramData%\CodeTwo\Office 365 Migration 3\Logs folder.

  1. Send this file along with the problem description to CodeTwo Support.


Be sure to zip all the files before sending them. Log files can grow big, but they also compress extremely well.

Viewing logs files

If you ever need to view log files yourself, you can manually browse through the %ProgramData%\CodeTwo\Office 365 Migration 3 folder. This folder contains many subfolders with different diagnostics (Fig. 3.).

Log files per se are stored in the Logs folder and might be considered human-readable. However, other files may not necessarily be considered as such. Most of them are kept in the XML format (Fig. 4.). Often, their names look like random characters strings. Those are unique identifiers (GUIDs) assigned to your jobs internally by the software. XML files can be viewed with Windows Notepad, Internet Explorer or any other text editor or web browser.


Make sure you only open XML files to view them and NOT to edit them. Saving manually applied changes to those files may corrupt them and crash the program.

Unless asked by CodeTwo Customer Support to manually browse the %ProgramData%\CodeTwo\Office 365 Migration 3 folder, it will be probably better to just use options available directly from the user interface in Administration Panel, such as reports, counters, and good news / bad news.
