MAgE reports the following error and a user fails to fully sync:
To resolve this error follow these steps:
1. Find the Item ID from the Trace line immediately after the error. So the ID from the example above is: 784A29A409A1D44E8703BEC17A36789D0005C4B3282C
2. Query the SQL database for the item:
SELECT * From FAILED_ITEM Where ITEM_ID = 0x784A29A409A1D44E8703BEC17A36789D0005C4B3282C
3. Then delete this Item ID from the table(s) the item was found in. In this case, the item was found in the FAILED_ITEM table only:
DELETE From FAILED_ITEM Where ITEM_ID = 0x784A29A409A1D44E8703BEC17A36789D0005C4B3282C
Once this item is removed from the SQL DB then MAgE should complete syncing the mailbox to 100% with no further interaction needed.
To identify the Subject line of the failed mail item you can run a SQL Query to identify failed items per mailbox. You'll need the Mailbox ID from the error message. For this case, the Mailbox ID is M13244. Enter this as the value for MAILBOX_ID= in the below query.
select F.MAILBOX_ID, M.NAME, M.ALIAS, F.DISPLAY_NAME, I.FOLDER_PROCESSING_ID, F.WELL_KNOWN_FOLDER, I.ITEM_ID, I.SUBJECT, F.MESSAGE_SIZE, I.LAST_FAILED_TIME, I.REASON, F.ERROR_TEXT from ((dbo.FAILED_ITEM I join dbo.FOLDER_PROCESSING_INFO F on I.FOLDER_PROCESSING_ID = F.ID) join dbo.MAILBOX M on M.ID = F.MAILBOX_ID) where MAILBOX_ID=M13244
