Hi , I had the same problem with XP/OutLook2010/ZEG2.0.5.
As stated in the Documentation http://www.sogo.nu/files/docs/SOGo%20Native%20Microsoft%20Outlook%20Configuration.pdf When you add the account , You have to Go in the settings : "Click on More Settings and ignore the warning, if any, about Exchange being offline by clicking on Cancel ❏ From the Security tab, enable Always prompt for user name and password" I don't know why without this option Outlook think that the server is offline, is there any bug request link to this behaviour ? -- [email protected] https://inverse.ca/sogo/lists
