EWS Java Connection Getting Refused Intermittently #573
Description
Hi - We have a email client which connects to Exchange Server. The email client has been designed to be in-sync with exchange using ews-java-api 2.0. The email is connected to shared folder inbox. We do not find any major issue as per normal behaviour.
It is so happening sometimes, once-twice a day, the connection is getting refused with exchange. Not sure why is this happening.
We initially thought, it might any exchange confiiguration issue, but treid and tested. The exchange is always 100% up, it is a organization wide used via clients like outlook, and don't find any connections issue and there is no issue in that.
Sharing the code snippet which is used to connect to exchange sahred folder:
if (strSharedFolderStatus.equals("t")){
//Data fetching from Inbox folder of Shared mailbox
String strSharedMailBoxCredential=propEmailConfiguration.getProperty("shared-mailbox-credential");
Mailbox sharemailbox = new Mailbox(strSharedMailBoxCredential);
itemsChanged = eService.syncFolderItems(new FolderId(WellKnownFolderName.Inbox,sharemailbox), PropertySet.FirstClassProperties, null, 1, SyncFolderItemsScope.NormalItems, sSyncState);
}
else{
//Data fetching from normal inbox folder
itemsChanged = eService.syncFolderItems(new FolderId(WellKnownFolderName.Inbox), PropertySet.FirstClassProperties, null, 1, SyncFolderItemsScope.NormalItems, sSyncState);
}
Sharing the exception message:

Is this similar kind of issue faced by any other users, when sometimes in between, connection gets refused when it is already connected?
Any workarounds would be appreciated.
