SYMPTOMS
The Microsoft Exchange DXA does not ensure that Mail ALIAS (MAILBOX) names are truncated to 10 characters. Furthermore, the DXA does not remove invalid characters such as a comma.
If the total length of the user's alias is more than 10 characters, the names are discarded and never included in directory synchronization (dirsynch) operations. The application log shows an error and a warning for each name it discards. For example:
Event: 247
Source: MSExchangeDX
Type: Error
Category: MS Mail 3.2
Description: The e-mail address of the following transaction is not a
valid format. See previous events logged by the Microsoft Exchange
System Attendant component for details. The transaction is A User02,
MacGroovy@GroovyMac MSMAIL:User02, MacGroovy@GroovyMac. (Thread 0)
Event: 5
Source: MSProxy
Type: Warning
Category: none
Description: Microsoft Mail address failure. The Mailbox name
'MS:Microsoft/testproxy/User02, MacGroovy' is not valid. There must be
1-10 valid characters.
