Apologies. I have just checked the Windows folder and found that Outlook 2013 is installed it just that I have not used it and do not have a shortcut on my desktop. I have also just checked using a registry search in regedit. I thought there was an issue with the latest version of windows 10 related to regedit searches and had not previously performed the search. The problem still exists (searches do not end and have to be closed at which point regedit restarts) and it still seems to be a problem for searches towards the end of the registry listing. Anyway I have found Microsoft folders related to Outlook and Exchange.
I have just updated to the latest build of Windows 10 Home from Windows 8.1 Home on my HP Envy Laptop. Since then whenever I switch on my laptop I am getting a message about letting Exchange ActiveSynch Policy make changes to my computer. I understand that EAS has something to do with synchronising "devices" to my PC. I have Office 2013 but I did not install Exchange 2013. I use Windows Live Mail and Thunderbird for my two email addresses. I have three desktop PCs (one running Windows 10 and the other two running Windows XP) another small laptop (running Windows 10) connected by a local wireless network. The other Windows 10 devices were upgraded some time ago with a different build of Windows 10 and the message did not appear on them. They have not been used since before the latest build was issued so have not updated to it. Prior to upgrading to windows 10 on the HP Envy I occasionally connected a Samsung tablet and an Alcatel smart phone mainly for uploading/downloading videos or photos. The Samsung has an email set up but not the Alcatel. I have been unable to find any way of removing or disabling the EAS message. I have tried some of the suggestions found on the web but these do not work and in any case they all seem to be talking about an Exchange Server which I do not have.
Has anyone had this issue and is there a quick and easy way of dealing with it.
