MS Outlook: Sync Issues folder; Where and what is it?

What is the Sync Issues folder? Where is that folder located?This exists if you are using an Exchange account,the Outlook Hotmail Connector add-in or Office365 connector. In all cases, the Sync Issues folder is located in Outlook itself.

Folder List navigation

You should probably be in the Mail Navigation. To see the folder, you’ll need to switch to the Folder List Navigation. To get there, use the Navigation icons in the Navigation Pane, the Go menu or by pressing CTRL+6 on your keyboard.

Subfolders of Sync Issues

The main synchronization log is kept in the Sync Issues folder. The actual items involved are kept in subfolders called;

• Conflicts
• Local Failures
• Server Failures

When an item is in such a folder, it means its changes either could not be uploaded or download or the same item got edited on two separate locations at the same time.

Verify and move before emptying the folders

If you still need the items which are listed there, verify if they still exist in your mailbox and also exist on the server by using Outlook Web Access when using an Exchange account or Windows Live Hotmail if you are using the Outlook Connector.
If they are not, then you can move the item to a folder of choice and see if the changes get uploaded now. If everything is in order, you can cleanup the Sync Issues folder if you want.
