You connect to a Microsoft Exchange Server 2010 Client Access server by using an Internet Message Access Protocol (IMAP) application. You use the FETCH (BODYSTRUCTURE) command to request for a specific message. In this situation, Exchange Server 2010 may return an incorrect result. The string at the sixth position of "single-part structure" in the result should be in quotation marks. It should be "7BIT" instead of 7BIT.

For example, you expect the following result to be returned:

FETCH (BODYSTRUCTURE ("text" "plain" ("format" "flowed" "charset" "US-ASCII") NIL NIL "7BIT" 14 3 NIL NIL NIL NIL) FLAGS (\Seen))

However, the following result is returned:

FETCH (BODYSTRUCTURE ("text" "plain" ("format" "flowed" "charset" "US-ASCII") NIL NIL 7BIT 14 3 NIL NIL NIL NIL) FLAGS (\Seen))


To resolve this issue, install the following update rollup:
