offline mode and sync'd them... ;)

I always enable extra columns in the folder pane and add the size
column, so I can always see how big my folders are...

Yes, of course the indexes will be rebuilt, but that is normal when
messages are deleted/added. I meant they won't be affected in any
abnormal way...
