1906757 - Don't create duplicate message headers for EWS messages

Status: RESOLVED FIXED

(Thunderbird :: General, enhancement)

Description

[Sean Burke [:leftmostcat]]

Because we don't have transactionality in the message database, it is possible for a message sync with EWS to encounter only a partial failure. In this case, we may add messages to the database but not update the sync state, in which case a subsequent sync will reprocess any messages which previously succeeded. This will currently result in duplicate message headers.

Message header creation should be conditional on not finding any other messages with the same EWS ID.
