Description

[thouthi38]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.8) Gecko/20100202 Firefox/3.5.8
Build Identifier: Lightning 1.0b1

While setting up repeated events and sending invitations for Outlook users, the format of the event is not supported by Outlook

Reproducible: Always

Steps to Reproduce:
1) Create a new event
2) In the "Repeat" list choose "Custom"
3) In the "Edit Recurrence" choose "Monthly" (for example, I did not try other)
4) Tick the "Repeat Until" in the Range recurrence"
5) Enter a date, e.g. end of current month
6) In the "Recur on Day(s)" click a few days
7) Invite attendees and notify somebody who uses Outlook
8) The invitee receives an unsupported calendar event for the Outlook calendar
Actual Results:  
Unsupported Outlook calendar event is emitted

Expected Results:  
Create Outlook compatible calendar events

None, works if done one by one

Which Outlook version is the receiver using? Each Outlook version has problems with some variant, so it won't be possible to support them all.

Hi and thanks for taking into account this request
It happens with Outlook 2007 / SP2
It can also be reproduced on Outlook 2003, not knowing which SP
It precisely says the following:
"not supported calendar message.ics"

Please find hereafter details of the generated ics:
Sections, #1 by Lightning, Section #2 equivalent by Outlook
By the way: 
-- when sent by Thunderbird, only the first event is mentioned in the Event Invitation Box
-- when sent with Outlook all events are displayed in the box
-- Outlook does not have the (nice) CUSTOM feature with choice of any day in recurrence, you can only select days of week always in same order (may be the issue is here??)
-- when sending with the CUSTOM option, there's always issue

If I can help more, please let me know
Cheers

Comment 4

[thouthi38]

Again me

This actually works between 2 Lightning applications

Comment 5

[Philipp Kewisch [:Fallen][📱📆]]

As you've mentioned, Outlook doesn't seem to support selecting by days. Could you try importing the Lightning event into Outlook (not as an invitation, but normally into an existing calendar) ?

There's probably not much we can fix about this bug. You could try stripping information from the ics data (i.e removing CLASS, PRIORITY, etc attributes...leave the RRULE there) and then importing into outlook to see if there is some other property that is in the way.

If its just the RRULE that fails, if it works with a more standard type rule, then there's nothing we can do about this bug (not our bug).

[Martin Schröder [:mschroeder]]

Resolving as INVALID per comment#5, and hopefully Outlook is smarter these days.
