|I have uninstalled and installed Office on many machines and have never lost outlook settings. |
However the best thing you should do is, goto
and from there make a copy of each email account settings
I do this as a backup just in case something does go wrong, but to date i have never had to reinstate email account settings when upgrading from 2007 to 2010, and recently 2010 to 2013.
I also had to uninstall 2010 from a users laptop because office had encountered an error, when i reinstalled it Outlook settings were still there.
as i said though it is always a good idea to tke screen shots of the settins just in case.
