Why can I only go back 1 year when searching in an Outlook Shared mail box?

Question

We have a shared mail box in our Office 365 account, we use it to archive emails that we need to reference sometimes 2 - 3 years after the email was sent. When I complete a search it only provides me with emails going back 1 year from the sent date. Is there a way to change the settings on that shared box to search back further without going to the online version and searching in specific date ranges?

Answer 1

Hi, is the shared mailbox configured to cache downloaded folders?

If so, uncheck that option in Outlook and restart Outlook and search again:
