Hello Bert! I was able to reproduce the favorite loss issue and have escalated the issue to our development team for review.

Same on us! We need a fast fix we get many requests about this.

We have a fix for this now, and I believe we're planning on releasing later today with any luck!

Hey Guys, 

We just released the new version today. Please download it and try it out. Let us know if you have any issues. 

Thanks,

Just installed Build 8860 last night and we're seeing the Favorites folders disappear again from the top left of Outlook. They disappear at random intervals as far as we can see. Adding them back seems to persist through re-start of Outlook. But at some interval, they disappear again. In our case the disappearing folders are IMAP mailboxes (Gmail and others). The MAPI folders marked favorite stay.

I just opened a ticket to report.

Thats crazy..... it should be fixed.
