When the green bar runs across the bottom right, what does it signify? If we’re seeing it, we ought to know what it means. Compacting? Indexing? Perhaps this information’s already been posted somewhere, but I didn’t spot it. Thanks.
Hi,
do you mean green bar in rightside corner? That indicated synchronization process like in other email clients

Thank you, Jan. What confused me was that tonight I saw it move in an unexpected way. Instead of the usual single swipe, it moved repeatedly. Perhaps that represented some kind of hang-up in the synchronization process. I appreciate your quick reply!
you are much welcome
