Thanks for the quick reply and;
- Yes correct its communication with Exchange during restore of items.
- No its not a server throttling issue and we already have a policy that removes all limits
- The server is also not overwhelmed, i.e. no resources are constrained from source to path
I am not the developer on this, but will have one of my team members post back with additional information regarding the issue in short order. We have looked at this pretty thoroughly in terms of possible causes, i.e. network saturation, resource constraints for source and target machines and there is absolutely no issues there. That lead me to wonder if all other resources are not constrained can MAPI itself can get overloaded/saturated?
