This is commonly seen when an Exchange environment has been migrated from Exchange 2003. And it happens because the Alias names for the particular public folders have spaces in them (or a character that Exchange does not like).

Solution

1. On your Exchange 2007/2010 Server Launch the Exchange Management Console > Toolbox > Public Folder Management Console.

2. If you error is about OAB / Address books skip to step 5, If it’s to do with a public folder that your organisation has created, expand default public folders and locate one of them that’s causing the error (In the example above I’ve highlighted one called “1045 – Greengairs” > Select its parent > Then select it (in the central pane) and open its properties.

Error: The properties on this object have invalid data. If you click OK, default values will be used instead and will be saved if you do not change them before hitting Apply or OK on the property page. If you click cancel, the object will be displayed read-only and corrupted values will be retained.

4. Once removed apply the changes.

5. If your error references OAB or address books, expand system Public Folders > OFFLINE ADDRESS BOOK > Check the properties of ALL its child objects > and on the Exchange General tab remove any spaces or unusual characters.
