Duplicate folder structure in Outlook

Historical overview: I have been running 14 mail accounts distributed over 4 mailboxes (1 Exchange, 3 POP) perfectly since Outlook 2010 was released. One day I see duplicated items for the Exchange mailbox only in the To Do Bar [ATTACHED as Fig 1] and Reminders Window. At the time, I suspect its maybe WUS update causing it. Windows had recently released 16 patches for Win7. I went through one-by-one removing the patches, and then rebooting to see if it corrected the issue. It did not. Then I re-applied then all and removed the profile entirely, all the email accounts and all mailboxes to isolate the issue. I only created the Exchange profile and during the initial sync the mail structure duplicates with different icons on the second structure [SEE ATTACHED as Fig 2]. After Outlook is closed and re-opened, it resolves back to normal, however, then Reminders and the TO DO list duplicates. The actual items in the inbox do not. I have a rule setup to flag all messages.

I have performed the following steps:
- Recreated the mail profile 5x’s by deleted the mail profile and the OST file, rebooting & starting from scratch.
- Removed cache mode.
- outlook.exe /cleanreminders
- outlook.exe /resettodobar
- outlook.exe /safe:3
- I have already opened a case w/the SaaS exchange provider

all failed to remedy.

There is no /cleanprofile switch for Outlook 2010 anymore so I do not know what has replaced it.

Environment: Windows 7 Pro (fully patched), workgroup, Outlook 2010 (fully patched), Cloud Exchange Enterprise 2010 (fully patched).

@BCipollone: Thanks for your response! BB is available for us to use but we have do not thus far…only ActiveSync. I would assume because we can “enable it” and use it in less than 2 minutes that the server is running in the bg and is just waiting for activation. I will have to confirm w/the SaaS provider.

Try disabling activesync on one of the mailboxes.

Also, If you are using the same mail profile name when recreating might be worth trying a new name.
