Hi All,

 I am developing simple email client application using EWS Managed API. To sync with mailbox on exchange server i am using Synchronization concept of EWS Managed API. But every time i request to exchange server for any modifications(new mail, update or delete), i am getting modified items along with sync state. But Sync state is growing continuously for every request.

How to maintain this sync state if it grows for every request and How far this sync state will grow (what is the maximum size of this sync state). 

I am using this method to sync with mail box.

ExchangeService.SyncFolderItems

Any help would be appreciated.

Thanks
