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. For more information, see Office programs may crash with the FineReader add-in installed. If prompted, enter your password and choose Accept. 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. 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. 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. 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.
Select the check box next to an add-in you want to re-enable, and then choose OK. 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. 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. In the Profile Name box, type the name you want to use for your new profile. Note: The Add Account Wizard automatically searches for your mail server settings.
Choose Finish and you'll find the new profile name you added listed on the General tab in the Mail dialog box. Under When starting Microsoft Outlook, use this profile , choose Prompt for a profile to be used , and then choose OK. In the drop-down list in the Choose Profile dialog box, choose the new profile name you created. 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.
