Issue in Riva Cloud or Riva On-Premise
The following error appears in the sync logs:
Error - Error occurred clearing items: an internal server error occurred: [Error Contains Filter Wrong Type] The Contains filter can only be used for string properties.
Unable to initialize: an internal server error occurred: [Error Contains Filter Wrong Type] The Contains filter can only be used for string properties.
Some Exchange versions support searching with the "Contains" filter, while other versions do not. When using an affected version of Exchange Server, the error appears in the sync log when Riva tries to search items by category.
The solution depends on the Riva platform:
Note: The Sync.Ex.ExchangeVersionSupportsContainsFilterOnCategoryOverride advanced option is used by Riva only if it is added to the Exchange custom settings. It will not be used if it is added on the sync policy's Advanced Options tab or to the CRM custom settings file.
