A customer just upgraded to Office 365. They are saying that new email is automatically being deleted/moved to Deleted Items folder.
More info:
- There are many users and its happening to all mailboxes
- Each user opens multiple mailboxes but only one user opens all mailboxes.
- It happened when only one user had Outlook open. This user was the user that opens all the other users mailboxes.
- They swear they are not deleting the email manually. They seem to be reasonably computer literate so I don't think they are in fact manually deleting the email.
- Email accumulates in the inbox overnight but is only deleted/moved inappropriately during business hours when Outlook is being used.
- Email is deleted/moved after a while and not immediately. For example, test email I sent was deleted/moved after about 4 hours.
- Run outlook.exe /cleanviews
- Removed server and client side rules for all users
- Deleted and recreated Outlook profiles
- Disabled IMAP/POP3 in Office 365 management console.
- They previously had IMAP accounts and email was exported from the IMAP account then imported into Office 365 using Outlook 2010.
- They also have an issue where folders originally created while they were using IMAP accounts still have IMAP properties/views now they have been imported into Office 365. The default view for all these folders is "Hide email scheduled for deletion" and this automatically hides new email manually moved to these folders. They have to repeatedly manually modify the view and remove the filter.
Any help is appreciated.
manually deleted all client and server rules
