Outlook 2010 only starting in Safe Mode (KB3114409)
Seems one of the updates in this months Microsoft Patch releases has caused an issue it was trying to prevent rather than fixing it. (This is one of the many reasons we created SnaPatch for, to give a quick and easy rollback)
The KB3114409 update was to prevent Outlook 2010 from starting in safe mode.
The following Update was released this past Patch Tuesday and may have found its way into your respective environments via WSUS/SCCM Automatic Deployment Rules:
While the core objective of the above fix was (to provide a means) to limit Outlook 2010 opening in Safe Mode, a feature released in KB3114305:
It appears as though the patch is causing the exact opposite effect, where all users are forced into Safe Mode for Outlook and display preferences are not being retained.
This is still very fresh, meaning there may be other issues associated with this release.
The current workaround is to uninstall/prevent the hotfix – This returns functionality in those cases where the fix has caused issues.
For sites using Outlook 2010 with SCCM ADRs to deploy patches, I would encourage disabling this update. Sites using Lotus Notes are not affected, as this update is specific to Outlook (and not Office) 2010.
