I have an issue in an Online Scenario where the SubscritptionSyncInfo has grown to 2,7 GB. I have querried this table with XRM Toolbox and saw that it contains synchronization time stamps mostly from users who do not exist in the organization anymore. Actually the Customer pays for these 2,7 GBs per month but there is no given way for him to minimize the used storage size of the dbo.SubscriptionSyncInfo. Even the MS Support says there is no supported way how to delete old records of this table.
Is there a way to reduce the used storage amount of this table in Online Scenarios or for deleting these record by supported methods?
