Hi,
No idea if Cal/CardDav standard supports this, or whether this is server implementation specific, but it would be fantastic if optionally OutlookCalDavSync could sync the HTML / RTF content and attachments of contact Notes and Calendar Entry descriptions with servers. (I note there is a separate milestone 2.0 feature request for attachments, but this doesn't mention HTML/RTF - https://sourceforge.net/p/outlookcaldavsynchronizer/features/84/)
I regularly use formatted text and embedded attachments in both my calendar entry descriptions and contact notes in outlooks - but at present this formatting and attachments are lost in the server copy of these items when syncing.
In return this means I am never certain if I edit one of these entries on my Android phone or on an Apple Mac OS X that syncs with my Apple OS X Cal/Cardav server how OutlookCalDavSync will handle the change inbound to Outlook.
For example: If I edit the text version of a Contact Note on my phone that in Outlook has HTML / RTF formatting and an attachment, when I sync the change back to Outlook will the formatting and attachment be lost? I think the answer today is yes it is lost, without warning!
At a minimum I'd like a warning during Sync so I can choose what I want to do so there is no possibility of me loosing information in Outlook Contat Note and Calendar Description fields.
