SYMPTOMS
During a migration of user mailboxes from a foreign e-mail system to Exchange Server, using the Migration wizard, an event may be written to the Windows NT Application Event log as follows:

Event ID: 4088

Source: MSExchangeMig

Type: Error

Category: None

Description:

An error occurred accessing a message in folder '[folder name]' for user '[user name]'. This message will not be migrated.



CAUSE
Some of the reasons the event 4088 might be reported are:
 * When migrating a GroupWise 5.x post office, the folder name in the event may be the Calendar folder. The migrated user mailbox named in the event contains an e-mail message from GroupWise with instructions on how to import the *.sc2 files into the Outlook Calendar.
 * When migrating mailboxes to Exchange Server from a foreign e-mail system, some messages may be corrupted or in a format that cannot be converted by the Exchange Migration Wizard.



RESOLUTION
If the Event 4088 is describing a folder other than the Calendar folder, the following steps will help you troubleshoot the problem:
 * 1) Verify that messages in the folder specified in the events are viewable from the original mail system and do not appear corrupted, contain non-printable characters, and so on.
 * 2) Determine whether a one-step or two-step migration is being executed.
 * 3) Determine if the source extractor is the Migration wizard or an extractor written especially for the migration. See "Creating a Source Extractor" on the Exchange Server 5.5 CD, for more details.
 * 4) Attempt to import the *.pri and *.sec files into personal folder files, open them with Outlook, and view the folders that are reported in the event.
 * 5) Check the General tab of the Private Information Store Properties page to make sure that the limit set for the Prohibit send and receive (K) value is not too low for the size of the mailboxes being migrated.



MORE INFORMATION
In reproductions or event logs received from customers, the folder names have been different, depending on the message that cannot be migrated.
