We are using Office 365 Outlook online and through local Outlook 2010 and 2013. Emails that are about 2 months old go missing from conversations. The attachments are not greater than 1 MB and there is no archive policy set. The email inbox is not close to full (only 0.5-4 GB used out of 25 GB).
There are cases where an email that is not as old is missing when it has an attachment compared to older emails without attachments.
Is anyone else having this issue?
Thanks
