I have several desktop and laptop computers with the current version of Outlook running in Windows 10. I never looked at the item number counts very closely until tonight when I had to rebuild some profiles. The same email account on 3 different computers shows a different number of unread items in the inbox. The account is an outlook.com account. Why would the numbers be different? (I have over 11,000 items, so to do a comparison to find the differences is probably out of the question. TIA.
