Searching by Message-ID header - MS Exchange 2010

[mattk-]

Searching by header against Microsoft Exchange (2010) fails.

Apparently Exchange does not support UTF8 (http://lists.horde.org/archives/bugs/Week-of-Mon-20110815/057209.html)

Example:

var searchCondition = SearchQuery.Header("Message-Id", messageId);
var ids = _client.Inbox.Search(searchCondition, _cancellationToken);

ImapFolder.Search adds CHARSET UTF-8:

if (args.Count > 0)
    command += "CHARSET UTF-8 ";

From the log:

C: A00000006 UID SEARCH CHARSET UTF-8 HEADER Message-Id <37cde6de-915e-4259-b8af-cff8381daae4@journal.report.generator>
S: A00000006 NO [BADCHARSET (US-ASCII)] The specified charset is not supported.

Thanks for reporting this!

I have to agree with the poster of that email in the link you gave, it's 2014 and Exchange still doesn't implement UTF-8? :-(

I fixed this in git master by using the US-ASCII charset unless the search text actually contains non-ASCII characters.
