How to open Microsoft Outlook in safe/offline mode?
Sometimes, you may need to open Microsoft Outlook in special modes, such as the safe mode, the offline mode, etc. In this article, I will show you how to quickly open Microsoft Outlook in the safe mode and in the offline mode as well.
Normally when Microsoft Outlook gets corrupted by something such as third-part add-ins or extensions, it will restart automatically in the safe mode. If you want to manually open Microsoft Outlook without running any add-ins, you can open Microsoft Outlook in the safe mode easily.
Before opening Microsoft Outlook in the safe mode, please close all Microsoft Outlook programs firstly.
Step 1: Open the Run dialog box with pressing the Windows key and R key on the keyboard at the same time.
Step 2: In the Run dialog box, enter the outlook.exe /safe in the Open: box. See screen shot:
Step 3: Click the OK button.
Then Microsoft Outlook opens without loading any third-part add-ins.
Note: It’s easy to exit the safe mode and switch to normal view with restarting your Microsoft Outlook.
Open Microsoft Outlook in offline mode
Do you know Microsoft Outlook allows users to disconnect from the mail server manually? If you do not want to receive any emails in some time, you can make Microsoft Outlook work offline with disconnecting Outlook from the mail server temporarily.
In Outlook 2007, please click the File > Work Offline.
In Outlook 2010 and 2013, go to the Preferences group on the Send/Receive tab, click to highlight the Work Offline button.
Note: If Microsoft Outlook is working offline, you will view the Working Offline (or Offline in Outlook 2007) on the Status Bar at the bottom of Microsoft Outlook. See screen shot:
Meanwhile, you will see the following Outlook icon at the Windows Taskbar if the Microsoft Outlook 2010 and 2013 is working offline.
Note: If you want to connect Microsoft Outlook to the mail server now, please click the Work Offline button on the Send/Receive tab again in Outlook 2010 and 2013, or click the File > Work Offline in Outlook 2007.
START OUTLOOK OFFLINE WITHOUT INTERNET ACCESS: (Best for Microsoft Exchange Mailbox situations)
1. Click Start > Type outlook.exe > Right click > Open File Location
2. Shift Right Click on Outlook > Copy As Path
3. Windows Key + R (to open Run Box) > type wf.msc and click ok.
4. RIGHT click "Outbound Rule" > "New Rule"
5. Program > Next
6. This Program > Ctrl V > Remove the double quotes at the beginning and end. > Next
7. Block the Connection > Next
8. Name it something: BLOCK OUTLOOK > Finish
You can now run outlook offline without having to changing stuff in the registry. The registry option isn't hard, but it's a hex entry which can be difficult to handle. AND, blocking it with the firewall guarantees no inadvertent deselecting "Work Offline." You will see at the bottom right that Outlook is just "disconnected." The "Work Offline" mode will not be enabled, but your Outlook will have no internet access.
When you're done trying to salvage the career-ending email from going out, you can do the following to undo the outlook block.
1. Windows Key + R (to open Run Box) > type wf.msc and click ok. (Assuming you already closed it)
2. Click Outbound
3. Right Click BLOCK OUTLOOK > Disable Rule (or Delete if you don't think you'll ever need it again).
With Win10 Settings Panel you can now set a Network Adapter as "Metered" - When in "Metered" State, Outlook will not connect. Confirmed in 2013/2016. Along the same lines as MV's post but would still provide network access to other items.
However if your IT admin has prevented you from modifying computer settings, you can also pull a network cable or turn off Wi-Fi, unplug wireless router.
Problem is, I can't open Outlook unless I'm online. And I can't get online, but need to read past emails. These instructions don't help at all, because you have to have Outlook *already* open in order to *get* offline.
