Subject: Emailing: domain first name last name
Sent: 05/10/2005 09:29

The following recipient(s) could not be reached: on 05/10/2005 09:29
This message is larger than the current system limit or the recipient’s mailbox is full. Create a shorter message body or remove attachments and try

sending it again.


Can be Set/Fixed in various places.

1. In Global settings,

In Exchange Manager Global Settings > Message Delivery > right click it > Properties > > Defaults > Check Send/Receive and Recipient limits

2. In Connector Setting (Note: You may not be using connectors, don’t panic if there is not one there).

In Exchange Manager > Administrative Groups > First Admin Group > Routing > Group > Routing Group Name > Connectors > Right Click > Properties > Content Restrictions > Allowed Sizes > Check the Only Messages less than box.

3. In SMTP Virtual Server Settings,

Administrative Groups > First Admin Group > Routing
Group > Servers > Server name > Protocols > SMTP > SMTP Virtual Server > Right Click > Properties > Messages.


If that won’t fix the problem it may be set on a user level

4. Open Active Directory Users and Computers > go to user properties > Exchange General > Delivery Restrictions.
