Recently I face issue some of the user’s outlook 2013 connection random disconnecting and are unable to configure their Out Of Office settings, they would get an error message when trying to open their OOF settings to set them. Some users had no issue while others got the error. Both environments were Exchange 2007 on latest Service Pack/Update Rollup & had a few users running Outlook 2013; only a few of which were having this issue.
After lot of brainstorm I found some solution in my favorite place social Microsoft forum related issue with Outlook security update. After following the same and uninstalling KB2837618, rebooting the client, & re-creating the Outlook profile then Out Of Office started working again.
After that gone through entire KB it appears this is a known issue:
- If you are using Outlook to connect to a Microsoft Exchange Server 2007 mailbox:
- You receive an error message that resembles either of the following when you try to configure Automatic Replies (Out of Office):
Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later.
- You cannot retrieve Free/Busy data for calendar scheduling.
- Add-ins that use the Account.SmtpAddress property no longer work.
These features rely on an underlying Autodiscover technology. After you install this security update, Autodiscover may fail for Exchange 2007 configurations. Therefore, Outlook features that rely on Autodiscover will also stop working.
Microsoft is researching this problem and will post more information in this article when it becomes available.
It appears the reason only random Outlook 2013 clients were experiencing the issue was because not all of them were up to date updates. So my suggestion is always keep Messaging environment up to date as per Microsoft recommendation updates.
