Use the article below to enable pipeline tracing. Property validation is done to ensure corrupted items are not replicated such as leading or trailing white spaces which is a common one.
For instance, in a few cases we've seen this output in the TXT file:
Microsoft.Exchange.Data.Storage.PropertyValidationException: Property validation failed. Property = [{00020329-0000-0000-c000-000000000046}:'Keywords'] Categories
Error = Element 0 in the multivalue property is invalid..
In this case it's complaining about the Categories property. This will happen if the public folder in question contains items on which the Categories property is set to be blank - such as with a single space - instead of truly
being empty. You can see this by going into Outlook and choosing to view items by Category. You should find that there are two different sets of items with "None". To correct the problem, simply clear the Category on all of the "None" items using Outlook.
You may have to set them to some other category and then set them back to None. Once the Categories property is truly clear, you'll only have one set of items that show "None", and the items will replicate successfully.
