outlook requiring password after exchange reboot

  • 772

We recently moved from Exchange 2003 to 2010, and have noticed a quirk that is annoying us.

If our exchange server (single server) goes down, ie it gets rebooted, or client loses connectivity (or for example a reboot is done overnight and the users computer is on at the time) they will be prompted to login, and will have to use the full domain\username notation in their username field in order to login again. Either that or reboot outlook.

Its not a big deal, but lots of inexperienced users are confused by this, and some dont realise they need to do something and thus their outlook sits there without receiving emails until they finally notice.

This used to be seamless, what do I have to do to get that back again?

    This is because the Outlook account settings were configured with "Outlook Anywhere" turned on. You can turn it off, if you do not want it.

    So that when exchange is rebooted, it will loose connection and restore it once it is back online, and it will not try to connect via https - Outlook Anywhere.

    I normally advice my user to restart outlook. If they enter their credential, it will change their connection to exchange from native connection via lan to HTTPS.

  2. You may see this behaviour if Outlook is configured to use Kerberos authentication only and the time difference between the client clock and the server clock is off by more than 5 minutes.

  3. I am also experiencing the same issue, it is odd that only some people experience it. Also I rebooted the server over the weekend whilst the PCs were off and some people were still prompted on Monday morning.

    I'm worried turning Outlook Anywhere off will affect my external users.

    Maybe you can try this, I have been unable to test it yet: Outlook > Tools > Account Settings > Change > More Settings Connection Tab > Uncheck "connect to my exchange mailbox using http".

    Have you installed all the exchange update rollups?

  4. Create a batch file on the all users desktop with the following:

    NET STOP msexchangerpc Shutdown -r -t 15

    Always use this to restart the system. It shuts down the service that causes users to have to log back in. Worked in our case at least.
