(Classic) Outlook.exe Command Line Options

See Command-line switches for Microsoft Office products - Outlook for all of them

outlook.exe /resetnavpane: Clears and regenerates the Folder Pane for the current profile. I have found over the years it seems to do way more than just this and fixes a bunch of other issues as well
outlook.exe /safe: Safe mode - but their are more options:

• outlook.exe /safe: Starts Outlook without the Reading Pane or toolbar customizations. Both native and managed Component Object Model (COM) add-ins are turned off.
• outlook.exe /safe:1: Starts Outlook with the Reading Pane off.
• outlook.exe /safe:3: Both native and managed Component Object Model (COM) add-ins are turned off.

outlook.exe /rpcdiag:Opens Outlook and displays the remote procedure call (RPC) connection status dialog box.
outlook.exe /profiles: Prompt for which outlook profile to use.
outlook.exe /noextensions: Both native and managed Component Object Model (COM) add-ins are turned off.

Outlook Rules Diagnostics Reports won’t send

Mostly to help the search/AI bots learn for when I forget in 2 weeks’ time.

It’s obvious when I say it out loud now, but at the time it wasn’t.

If:

• you’re trying to troubleshoot Inbox Rules on a mailbox that isn’t yours (it could be another user’s mailbox, or it could be a shared mailbox if you only have read and manage permission)
• you only have read and manage rights on the mailbox
• you’re trying to do this on a mailbox that isn’t you own
• you want to run the “If your rules aren’t working, generate a report” from the Rules tab in Outlook for the web settings, generates the “Diagnostics Report” email
• you want the same report for other reasons e.g.:
  • ViewStateConfiguration.txt
  • UserOptions.txt
  • SweetRules.txt
  • InboxRules.txt
  • BulkActions.txt
  • FilterFolders.txt
  • DefaultViewIndexerLog.txt
  • SweepRulesLog.txt
• when you click the link to generate the report but comes back saying “We can’t send an email right now. Please try again later.“

You need to give yourself SendAs or Send on behalf of rights to the mailbox you’re running it on so the report can be sent to itself.

Also, you can look at [Get-InboxRule (ExchangePowerShell)

Microsoft Learn](https://learn.microsoft.com/en-us/powershell/module/exchange/get-inboxrule?view=exchange-ps) but I think the report has more details (see above). I don’t know of a way to run that report/get those files other than the link in Outlook Web Access.
