====== Maximale Nachrichtengröße EAS ======

Es gibt keine EAS-Einstellung zur maximalen Größe von E-Mailnachrichten, EAS richtet sich nach den üblichen Regeln für den Versand von Nachrichten in der Echange-Umgebung. 

Allerdings ist der IIS standardmäßig so eingestellt, dass er max. 10MB große Nachrichten erlaubt:

<code>
Message size limits that are set for our environment is 25 MB but some of the sales users  Complained that

they are not able to attach document to message that is more then 10 MB in size. We have tested this & found the same thing.

Issue was that in the web.config file (C:\Program Files\Microsoft\Exchange Server\ClientAccess\Sync)

<httpRuntime maxRequestLength=”10240″/> was set to 10 MB.

We have changed it to 25600(25 MB) for resolving the issue.
