I recently ran into a bizarre problem with the Office 365 Hybrid Configuration Wizard, and solved it after a bit of trial and error. Hopefully this article will be a useful breadcrumb for future hybridizers.

1. Outlook 365 Won't Open
2. Office 365 Wont Open Windows 10

The HCW used to be a standalone Windows executable that you’d download. The Office 365 team (hi, Tim Heeney!) made the wise decision to turn it into a Click-To-Run (C2R) executable. The biggest benefit to using C2R is that whenever you click the link (which downloads the application’s manifest file) you get the latest version of the HCW, streamed directly to you from Microsoft’s servers. This ensures that everyone always gets the most up-to-date version, but it also introduces a few potential stumbling blocks.

Outlook 365 Won't Open

C2R application manifests aren’t executable themselves; they’re just XML files that provide some metadata about the application. With that said, on a properly configured Windows box, as soon as you download the manifest, the C2R helper application does its thing; it reads the manifest, streams the application, and launches it.

In my Exchange 2016 lab, that’s not what was happening. When I clicked on the HCW link in Internet Explorer, the little “Scanning.” infobar would flash across the bottom of the window, but that was it. Same thing in Chrome. Downloading the HCW manually using the Start-BitsTransfer PowerShell cmdlet got me the manifest file, but it couldn’t be launched. Of course, since the C2R launcher itself wasn’t launching, there were no log files to use to troubleshoot the problem. By contrast, when I downloaded the HCW onto my Windows 10 desktop, it would fail because I didn’t have the right prerequisites installed, leaving me a log file full of juicy details. All of the machines in my lab had the same problem, perhaps not surprising since they were built from the same Amazon Web Services AMI.

I spent some time doing the usual things: trolling the TechNet forums, searching random posts by people who had problems with the HCW (all of which were problems with what it did after launch, not problems getting it launched), and asking my smart MVP friends. Nada.

Then I had a hunch and opened the Default Programs control panel. For the “.application” file type, this is what I saw:

I changed the “.application” file type to be opened with Internet Explorer. Then I went back to the HCW link, clicked it, and was rewarded with a properly functioning copy of the HCW. Filed for future reference…

Start Outlook in safe mode and disable add-ins

Sometimes add-ins can conflict with Outlook. Starting Outlook in safe mode, which starts Outlook without add-ins loaded, can tell you if an add-in is the problem.

Note: If you enabled an ABBYY FineReader add-in, an outdated version of the software might cause an Outlook startup error. For more information, see Office programs may crash with the FineReader add-in installed.

Start Outlook in safe mode

1. Choose Start > Run.
2. Type Outlook /safe, and choose OK.
3. In the Choose Profiles dialog box, accept the default setting of Outlook and choose OK.
4. If prompted, enter your password and choose Accept.

Tips:

• How do you know you're working in safe mode? You'll see a label similar to the one below at the top of the screen.
• The Outlook icon on your taskbar also alerts you the program isn't operating normally.

If Outlook does start in safe mode, then the problem is likely with one of your add-ins. You'll need to disable all of your add-ins before restarting Outlook.

Disable add-ins

1. In the upper-left corner of Outlook, choose File > Options > Add-ins.
2. At the bottom of the View and manage Office Add-ins, make sure the Manage box shows COM Add-ins, and then choose Go.
3. As a precaution, when the COM Add-ins listing of your current add-ins opens, do one of the following:
   • Manually record the title of every selected add-in listed under Available Add-ins.
     or
   • Take a screenshot of the property sheet and save the image to a location of your choice.
4. After you've captured the titles of the selected add-ins, clear all selected check boxes, and then choose OK.
   Caution: Click a check box to clear it. Don't select an add-in and choose Remove. If you have administrator rights, you could actually delete the add-in. For this troubleshooting exercise, you want to disable, not delete, an add-in.
5. Choose File > Exit.

Restart

1. Choose Start > Run, and in the Open box, type Outlook.
   Note: If the program loads properly, it's likely that one of your add-ins is the source of the error and you need to identify which one. To determine which add-in is the problem, enable one add-in at a time.
2. In the upper-left corner of Outlook, choose File > Options > Add-ins.
3. Select the check box next to an add-in you want to re-enable, and then choose OK.
4. Repeat all steps until you've re-enabled all of the original add-ins and revealed the source of the error.
   Important: Remember, if Outlook opens in safe mode, you've revealed the add-in you just enabled as a source of the error.

   • Restart Outlook again and disable the add-in you enabled that produced the problem, and then start Outlook.
   • Make sure you go through the restart-disable-restart process for every add-in that was originally enabled in Outlook. An error could be caused by more than one add-in.

Create a new Outlook profile

Your profile contains your Outlook settings. Occasionally, that profile can become corrupted. You can determine if it's corrupt by creating a new profile and changing which profile is used when Outlook starts.

1. To open the Control Panel, do one of the following:
   • For Windows Vista or Windows 7, choose Start > Control Panel.
   • For Windows 8 and Windows 10, choose Start, and then type Control Panel.
     Note: For Windows 10, in Control Panel, make sure the View by box in the upper-right corner is set to Category.
2. Choose Mail.
3. In the Mail Setup - Outlook dialog box, choose Show Profiles > Add.
4. In the Profile Name box, type the name you want to use for your new profile.
5. On the Auto Account Setup page for the Add Account Wizard, under E-mail Account, fill in Your Name, E-mail Address, and Password, and then choose Next.
   Note: The Add Account Wizard automatically searches for your mail server settings.
6. Choose Finish and you'll find the new profile name you added listed on the General tab in the Mail dialog box.
7. Under When starting Microsoft Outlook, use this profile, choose Prompt for a profile to be used, and then choose OK.

Use a different profile

1. Restart Outlook
2. In the drop-down list in the Choose Profile dialog box, choose the new profile name you created.
3. Choose OK.
   Note: If Outlook starts normally, then you've identified your Outlook profile as being corrupt and the source of your problem.

Should you decide to remove a profile, back up the data files first. All offline cached content will be deleted when you choose Remove. For more information, see Introduction to Outlook Data Files (.pst and .ost).

Repair your Outlook data files

Outlook stores all your email messages, meetings and events, contacts, and tasks in data files. These files occasionally might become corrupted. You can run the Inbox Repair Tool (scanpst.exe) to scan your Outlook data files and repair errors.

1. Exit Outlook to use the Inbox Repair Tool.
   Note: The content in the left pane is determined by the Outlook version you're using.
2. Visit the links below for instructions based on your version of Outlook.

Run the /resetnavpane command

The navigation pane is the leftmost pane in Outlook where you'll find your folder list and the icons to move between Mail, Calendar, People, and Tasks. Running the /resetnavpanecommand removes all customizations to the navigation pane.

1. Close Outlook.
2. Choose Start > Run.
3. In the Open box, type Outlook.exe /resetnavpane, and then choose OK.

Check if Outlook is running in compatibility mode

Compatibility mode is designed to help a program run on an older operating system. If Outlook is running in compatibility mode, you can turn that off and see if it fixes the problem.

Did you get an Outlook not responding error? Is Outlook stuck on a screen that simply says 'Processing'? Or does Outlook hang, freeze, or stop working when you're opening a file or sending an email message?

There are a number of possible reasons for Outlook to behave this way. We've presented the potential solutions in order from quickest to most time consuming.

Start Outlook in safe mode to fix 'Processing' screen

If Outlook stops responding at a screen that says 'Processing,' you can close Outlook, start it in safe mode, then close it and open it normally to fix the problem.

1. Close Outlook.
2. Launch Outlook in safe mode by choosing one of the following options.
   • In Windows 10, choose Start, type Outlook.exe /safe, and press Enter.
   • In Windows 7, choose Start, and in the Search programs and files box, type Outlook /safe, and then press Enter.
   • In Windows 8, on the Apps menu, choose Run, type Outlook /safe, and then choose OK.
3. Close Outlook, and then open it normally.

If Outlook isn't stuck at a screen that says 'Processing,' or this didn't resolve your issue, continue to the steps below. If those steps don't work, see Need additional help? at the end of this article.

Step 1: Is there a dialog box open?

Some things you do in Outlook ask for confirmation. For example, the first time you try to Dismiss All on a list of reminders, Outlook asks you if you're sure you want to do that. If you don't choose an option on that dialog box, Outlook won't let you do anything else. Check for open dialog boxes. Pressing Alt+Tab will help you switch from window to window and help you see what dialog boxes might be stopping Outlook from responding.

If you can't find a dialog box open, move on to the next step.

Step 2: Make sure Outlook isn't working on a large or long process

If you try to delete or move a large number of messages at once, Outlook can appear to hang, but really, it's working behind the scenes. Check the status bar at the bottom of the screen. If Outlook is performing some operation on hundreds or thousands of messages at once, it might appear to be stuck. Give Outlook a few minutes to finish the process and it should start to work again.
