Older emails getting archived

Copper Contributor

I have an user that wants to have all emails accessible in the outlook with out having to go to online archive. I have set the account to download all past emails, have checked to make sure auto archiving is turned off. Outlook will download all older emails for about 2 weeks and then they disappear and I will have to toggle the download all past emails again for it redownload all the past emails. Currently that is not even working and we are having to go into the online archive and import all emails to the desktop Outlook. Is there a way to make this stop. We have a retention policy of 10 years. Once it reverts back the user can only go back about 2 years.

There's no "revert" functionality for retention policies. If the items were moved to the Online archive, you either have to move them back manually via Outlook/OWA or use an EWS-based solution (for example this script https://github.com/David-Barrett-MS/PowerShell-EWS-Scripts/wiki/Merge-MailboxFolders.ps1).
Either way, you should update the retention policy assigned to the user in order to prevent further items being moved.
