Hi Dennis, 

Backing up user chats have a few requirements.  First, this is only supported in 11.34 and higher.  Second, this requires us to use the Microsoft’s paid export APIs which will add some additional costs to your subscription.  Do you have those configured?

Thanks. OK no we don’t uses this.

Dennis
