Notes 9.0.1 sends corrupt VCALENDAR file in invitation reply

hcl-bot · October 28, 2014, 5:58am

when I accept a invitation from a external sender, than Notes sends a corrupt VCALENDAR file in the reply.

Here’s the according part from the outgoing email (invitation reply):

–=mixed 1B3B9A7BCC1967EFC1257D7F003B6B7A=
Content-Type: text/calendar; method=“REPLY”; charset=“UTF-8”

The mail system (Exchange 2010) of the Invitation Sender can’t process the reply.

From my view it’s because Notes writes the sequence 3D after the equal sign in the ATTENDEE line:

ATTENDEE;PARTSTAT=3DACCEPTED;CN=3D"Manfred Pausch/XXX/YYY/ZZZ"
;RSVP=3DFALSE:mailto:Manfred.Pausch@our-domain.tld

When I accept the invitation request in iNotes, than the VCALENDAR file is correct and the mail system

of the invitation sender can process the reply.

Some information about my environment:

Server: Domino 9.0.1 FP1

Client: IBM Notes 9.0.1 FP2 on Windows 8 (but problem also occurs on Linux and Windows 7)

Anybody some ideas?

Thanks in advance

Subject: FYI, thats the Quoted-Printable encoding

QP encoding is used to “encode” certain characters into “safe” sequences that can be transmitted over MIME and then “decoded” later back into the characters you had originally. What you see is perfectly legal and correct. If you QP decode your data you will see it looks fine:

Content-Type: text/calendar; method=EPLY"; charset=TF-8"

Subject: no solution, but a work-around

Thank you all for your replies and explanations.

In the meantime I did additonal testings and found out that the reply is slightly different when I

accept a invitation “with comments”. Even when I don’t enter any comment with my accept then

the attached VCALENDAR file looks like this:

–=mixed 92BE6F32ADA3DE27C1257D80003D0C1B=

This can be processed by the external Exchange server and the external user sees the accept in his calendar.

For me this is not a nice solution but will be good as workaround for the next few months until we have to migrate to Exchange :-\

Subject: outlook has been quirky ffor me.

Ive had to write multipart MIME & vCards specially just so Outlook will read them.

Bet theres something about this format too.
