Domain: Exchange

Code: ErrorTemporaryServerError 

Type: Temporary error (Please try again later. If multiple temporary errors occur, contact support.)

Description: This is a temporary server error. In most cases, re-trying what you were doing will solve the issue. However, in case it does not, and you run Exchange Server (EWS), it might be related to the number of bytes that a web server will have available for the current operation.  This article from Microsoft's Knowledge Base contains a suggestion to solve this issue.

If the issue still persists after trying both suggestions listed above, please contact support and provide as much information as you can regarding the issue.
