The `[SOGoFolder:aclUsers]` returns a reference to a `NSArray`
which is being modified in the `for` loop making fail when
more than one user is in the ACL with `NSRangeException`.
Outlook sets recipient type of Required attendees as MAPI_TO and
optional ones as MAPI_CC, so the fix is just to not only iterate
over the "to" list of recipients but also the "cc" one. We're
also setting the proper iCal value for this case (OPT-PARTICIPANT
instead of REQ-PARTICIPANT)
In [MS-OXOCAL] Section 2.2.4.10.7 says the recipient type is 0x01
as Required and 0x02 as Optional and other documents such as
[MS-OXCMSG] 2.2.3.1.2 indicates that MAPI_TO is 0x01 and MAPI_CC
is 0x02, that's why is stored in 'to' and 'cc' respectively.
SOGo does not create BYDAY mask in weekly recurrence, so
we have to guess it from the start date's day of week.
In other case, the event is not exported to Outlook and it
says that is corrupted.
According to [MS-OXICAL] Section 2.1.3.1.1.20.13, the EXDATE property
must be written only if there are ocurrences from the series that have
been deleted and before this commit ModifiedInstanceDates were also
included.
We check against every ExceptionInfo from exception ocurrences of the series
to know if the ocurrence was deleted or only modified.
This makes sent mails are not longer automatically copied
to Drafts folder.
Reasoning:
When Outlook sends a mail, OpenChange submits the message and
copy the message to Drafts folder. Afterwards, the client asks
to move this message using SyncImportMessageMove ROP from
Drafts to Sent. During this movement, the message is unregistered
from the indexing database. If the client has updated Drafts
folder before that movement, then the client will keep this
message as the MID is not returned in oxcfxics download sync
as deleted. Setting the message as soft deleted, make it work.
In this way, we do not modify the flags (\Seen) on preloading.
The IMAP server returns the content without .peek section so
it is removed.
This also performs the modification intended by the following
Pull Request:
https://github.com/Zentyal/sogo/pull/50
That tried to avoid set \Seen flag when preloading message bodies
on synchronisation. But in this case we are not incrementing the
modseq as we are not modifying any messages flags.
As required by [MS-OXWSMSHR] Section 3.1.1 to display the share
object message correctly and be able to open the shared calendar
directly from the message.
It acts as a proxy of MAPIStoreMailMessage and it manages the properties
defined in [MS-OXSHARE] Section 2.2 by storing them in the mail message
as eXtensible MIME headers which starts with X-MS-Sharing.
get_AppointmentRecurrencePattern() can fail to parse the input data, added a check to avoid setup the recurrence pattern in that case. This should only happen when input data is incorrect.
