Hi. I am running outlook 2010 on my computer and also runs OWA 365 occasionally.
Searching for mails in inbox from a sender shows 12 mails in outlook 2010 and 8 mails from same sender in OWA. By searching around in OWA I do find the rest (4) connected to different other mail contacts. I remember I have seen the same in gmail long time ago. I did leave gmail for this reason. Could someone explain me what is happening?
