PRB: Cannot Restrict Multi-Valued Property in Exchange Message Store Provider

When you attempt to restrict a multi-valued property in Microsoft Exchange Message Store Provider, you may receive the following error message:

Exchange Message Store Provider does not support property restriction on multi-valued properties.

This behavior is by design.

Multi-valued properties can be used in property restrictions if the service provider that is implementing the table supports them. If supported, multi-valued property tags can be used anywhere single-valued property tags can be used. For example, the Exchange Address Book Provider supports restrictions on multi-valued properties.
