Hi
We are having an increasing problem with meeting requests that originate external to our organisation. When the internal recipient responds (either accepts or declines the invitation) the response gets stuck in their Outbox.
They receive the following message:
Remote Server returned '554 5.6.0 STOREDRV.Submit.Exception:TextConvertersException; Failed to process message due to a permanent exception with message data truncated TextConvertersException: data truncated'
The user is able to open the meeting response in the Outbox (double-click the message) and click Send and the response will then go normally.
We are using Outlook 2013 SP1 with Exchange 2013 SP1 CU9
Anyone have any ideas??
Thanks
Sean
