Outlook 2016 Inbox shows Unread: -1 RRS feed

  • Question

  • My Inbox using Outlook 2016 is showing Unread: -1 messages.  I have tried the suggestions that have been previously posted for Outlook 2013, which did not worked.  I have also run the scanpst to repair the pst file.  I'm not sure what to do now.  Ideas?I would post an image, but the forum will not allow me to post yet.

    Thank you.

  • Hi Jim,

    Do you mean the Unread count number next to the Inbox folder is shown -1 in Outlook 2016? If possible, please share a screenshot to a web page (for example, OneDrive) and post the link here.

    Please restart your Outlook in safe mode to narrow down if the issue is related to any third-party add-ins:

    Press Win + R to open Run in Windows, type Outlook /safe, press Enter.

    Additionally, please go to Control Panel > Programs and Features, select the Office application, click Change > Repair (Online Repair for Office 365 Proplus). Then create a new profile and reconfigure this account in Outlook. Confirm if it works.
