I have installed 3.0 beta and done the configuration with care ... then launched the first synch.
On my Android phone the result is: more than 3600 events are now in my Outlook Mail under the outgoing folder and are sent again to my contacts (I use my agenda to organize meetings with customers at least 3 meetings per day).
That's really ennoying because my contacts will receive "old" meeting invitations, maybe somme several time judging by the amont of events!
I'm currently trying to empty my Android mail outgoing folder

What's the reason of this behaviour? Is it possible for the first sync just to synchronize event "in the future" which are less numerous and can be "accepted" / understood by my meetings attendees when received (a sort of "reminder")?
Thanks for your help,
PS: this pb already occurs in the past!
PS 2: my config
- Thunderbird under Windows
- Android with emails client configured for my corporate outlook account.
