NM: "Size of attachment ... exceeds size limit (0.x MB versus 0 MB limit)" (4315708)

Issue

The migration log reports the following notification message:

"Size of attachment ... exceeds size limit (0.x MB versus 0 MB limit)" even though the Advance Settings / Process attachment greater than 0 MB as files is set correctly.

Cause

The underlying cause is that the Signed MIME attachment is in a 'r4 style' format and the attachment cannot be processed correctly. 

Analysis

Notes Migrator uses MIME data to process the message body when possible, but for this message, attachments never show up in the MIME data retrieved from Notes. The root cause seems to be a result of the attachments being stored as ‘r4 style’ attachments in the problem message. ‘r4 style’  

• The attachments all appear at the end of the message instead of in the body of the message.
• The attachments appear as $FILE objects in the message document but do not appear in the MIME data.

Also, the body of the original message does not appear in the MIME data, which is why the migrated messages contains 1-byte .EML attachment. 

Check your Notes Migrator advance setting for the "Process attachment greater than 0 MB as files" as show in the attached screen snapshot. Press on the "?" for additional settings.

Solution

This issue was resolved in Notes Migrator 19.03 and we recommend customer upgrade Notes Migrator 19.03. 

• To start the upgrade process to 19.03, ensure that you close the worker app for each worker. 
• Install / upgrade to Notes Migrator 19.03 on the controller.
• When complete, run an IISRESET.
• Start each worker. The workers will automatically upgrade to 19.03.
• Run a test migration. The ‘r4 style’ attachments should now migrate properly.
  

Workaround 

There are two solutions to work around this limitation if an upgrade is not possible 

1. These attachments can be downloaded to the users local drive from the Lotus Notes email. These files can be attached to an Outlook email if these files need to be sent in the future.  
2. The user can email (forward) the Notes message(s) to their Exchange mailbox.
