Manages MIME simplification in Domino 8.5.
Important: In Domino 8.5.1 and later, you can manage these features
in the mail policy settings document and do not need to use NOTES.INI
When Notes sends workflow items, such as invitations, updates,
cancellations, and acceptances, to SMTP users, it converts the workflow items
to iCalendar items and embeds the iCalendar items into MIME. These SMTP users
could be Notes users, Outlook/Exchange users, or users of other clients. To
allow the iCalendar items to reference an HTML body and get the richest
rendering, Notes creates complex MIME. Exchange 2003 does not understand this
complex MIME and removes the iCalendar part. This results in an e-mail message
with an iCalendar attachment. If the recipient is on Exchange 2003 or if the
message routes through an Exchange 2003 server, the attachment must be opened
and accepted, and problems with workflow can occur.
To better support Exchange 2003 users, you can enable MIME simplification.
However, when MIME simplification is enabled, Notes cannot have a rich HTML
body. To prevent data loss, Notes puts the rich body content into an attachment
added to the e-mail message. For Notes users over SMTP in your domain, be aware
that the richness of the message body is therefore degraded, in the same way
that Notes degrades the richness for Exchange 2003 users.
MIME simplification is off by default, and controlled by the
DisallowRelatedIcalendarMime NOTES.INI parameter. As with any NOTES.INI
parameter, it can be pushed to clients using a policy. It is important to add
the parameter in the NOTES.INI file on both clients and IBM® Lotus® Domino®
servers, as conversion can happen at either place.
- 0 - Complex MIME conversion occurs as usual. No richness is lost, but
workflow problems may result with Exchange 2003.
- 1 - Complex MIME conversion occurs as usual, unless a meeting has
compatibility mode specified, in which case it is simplified for Exchange 2003
compatibility. Compatibility mode is represented by the text document property
of $ICAL_COMPATIBILITY_MODE and a "1" value means it is on. If a third party
creates the documents, it can set this property to control the generated
- 2 - MIME conversion is simplified. Richness, but no data, is lost for all
users outside your Notes domain that require MIME conversion). No problems
occur with Exchange 2003.

Do not use this setting on the server as of 8.5.1. Instead, use settings on
the Client Detection - Basics tab of the Mail policy settings document in the
Domino Directory. For more information, see Improving interoperability for users of calendars in
