some TAB symbols.

user may experience an issue in a scenario where an
application that generates reports in plain text format uses
TAB symbols to format data into a tabular structure. In
such a scenario, when the recipients receive such a
message, the recipients may see that the data in the message is
- When recipients use MAPI clients or POP3/IMAP4 clients to
access the MIME message, the recipients may still encounter this issue. This is
because the MIME message is converted by the transport component when the
message is delivered.
- If the message was created by an internal MAPI client,
internal recipients that use MAPI clients do not encounter the problem. This is
because the message is not a MIME message. However, internal recipients that
use POP3/IMAP4 clients may still encounter the problem. This is because a
message always is converted to a MIME type when the message is retrieved from
the mailbox store.
