Mac Outlook Missing Microsoft Store Icon

I’m trying to make a change to my Mail Profile and I was advised to go to Control Panel-> Mail. However, when I go to Control Panel, there is no Mail icon.

Where exactly is it located?

Features not yet available in the new Outlook for Mac. There are several features that are available in the current version of Outlook for Mac for Microsoft 365 that aren't yet available in the new Outlook experience. S/MIME - Now available in Current Channel version 16.45 (21011103. Microsoft will be blocking injection-based plugins from running in Outlook for macOS, and only allowing add-ins available through the Microsoft store. Initially planned for June 2020, this timeline has been postpone until later 2020, to be determined by Microsoft. I'm using the Outlook 2016 client on Mac. Even though during their April release, Microsoft had confirmed that Groups is now available for Outlook on Mac, the icon is still missing from my MacBook Air Outlook client. I've tried removing my account and signing it again, still no luck.

The Mail icon to manage your Outlook Mail Profile may sometimes be hard to find indeed, especially on Windows 10.

When you are using Windows 10, make sure you open “Control Panel” and not “Settings”. When you open the Start Menu, simply type “Control Panel” to find it.

Another reason why you may not be able to find it is when you’ve installed Office or Outlook via the Windows Store. In that case, there is no Mail applet added to Control Panel.

Luckily, there are 2 additional easy methods to open the dialog to manage your Outlook Mail Profiles.


The Mail Setup dialog allows you to manage or reset your Outlook email configuration outside of Outlook.

Note: For instructions about managing your accounts and recreating your mail profile via the Mail applet see; Adding/Recreating a Mail Profile.

Method 1: Control Panel

If your Control Panel is in the classic icon layout, you should see the Mail applet directly in the list of icons.

If your Control Panel is set to “View by: Category” you can find the Mail applet in;

Mac Outlook Missing Microsoft Store Icon
  • Windows 7: User Accounts and Family Safety
  • Windows 8: User Accounts and Family Safety
  • Windows 10: User Accounts

You can also quickly find it by typing “mail” in the search box in the right top corner of Control Panel.


Mail applet of Outlook 2016 in the Control Panel of Windows 10.

Method 2: Manage Profiles from within Outlook

When you are using Outlook 2016, Outlook 2019 or Office 365, then you can also open the Mail Setup dialog via;

  • File-> section: Info-> button: Account Settings-> Manage Profiles


Opening the Mail Setup dialog from within Outlook.

Method 3: Command line switch

When you are using Outlook 2016, Outlook 2019 or Office 365 (version 1806 or later), then you can also open the Mail Setup dialog with the /managemailprofiles switch.

  • Start-> type; outlook.exe /manageprofiles


Opening the Mail Setup dialog from the Start Menu with a command line switch.

Note 1: There is a space in the command after outlook.exe.

Note 2: For an overview of the available command line switches and more details on how to use them see the guide; Command line switches for Outlook.

Summary

This article contains an overview of the Microsoft Outlook AutoComplete list (also known as the Outlook Auto-Complete list). In addition to describing the feature, this article contains more information and step-by-step instructions for advanced users to manage the list.

More information

Outlook maintains the AutoComplete list. The list is used by both the automatic name-checking feature and the automatic completion feature. The AutoComplete list, also known as the nickname cache, is generated automatically when you send email messages from Outlook. The list contains SMTP addresses, LegacyExchangeDN entries, and display names for people to whom you have sent mail previously.

Note

The AutoComplete list for Outlook is specific to Outlook and is not shared by Outlook Web App (OWA). OWA maintains its own AutoComplete list.

The following sections provide information about the AutoComplete feature.

Limit to the number of entries

Outlook limits the number of entries that you can save in the AutoComplete list. After you reach this limit, Outlook uses an internal algorithm to determine the best names to remove from the list. It does this based on a usage weighting. So, you may find some names unexpectedly removed from your nickname cache. There are two general approaches that you can use to avoid this situation:

  1. You can proactively remove AutoComplete list entries that you no longer need. This is the preferred approach. For more information about how to do this, see the How to remove AutoComplete list entries one at a time section.
  2. You can increase the limit for the nickname cache. Because this configuration is untested, we don't recommend it. If you have a larger nickname cache, you could also lose a larger number of cached entries if your nickname cache becomes unusable because of corruption. For more information about how to increase the limit, see the How to change the limit for the AutoComplete list section.

The limits are as follows:

  • Outlook 2016: 1,000 entries
  • Outlook 2013: 1,000 entries
  • Outlook 2010: 1,000 entries
  • Outlook 2007: 2,000 entries
  • Outlook 2003: 1,000 entries

How to import .nk2 files into Outlook 2010, Outlook 2013, and Outlook 2016

Microsoft Office Outlook 2007 and earlier versions store the AutoComplete list in a nickname (.nk2) file on the disk. Outlook 2010, Outlook 2013, and Outlook 2016 store the AutoComplete list as a hidden message in your primary message store. Outlook 2010, Outlook 2013, and Outlook 2016 let you import the older .nk2 files.

For more information about how to import .nk2 files in Outlook 2010, see Import Auto-Complete List from another computer.

How to copy the AutoComplete list

The steps to export and import the AutoComplete list are different, depending on the version of Outlook that you're using.

Outlook 2016, Outlook 2013, and Outlook 2010

    Note

    Before you delete the IPM.Configuration.Autocomplete message, you must export the message by using the steps in the How to copy the AutoComplete list section.

    To delete the existing AutoComplete message, follow these steps:

    1. In the Subject column, locate the item that has the subject IPM.Configuration.Autocomplete.
    2. Right-click the item, and then select Delete message. This opens the Delete Item window.

The AutoComplete information is imported from the IPM.Configuration.Autocomplete_<hexadecimal code>.msg, where the placeholder <hexadecimal code> represents a long string of numbers and letters.

Outlook 2007 and Outlook 2003

The steps to copy the AutoComplete list in Outlook 2003 and Outlook 2007 are different. This is because Outlook 2003 and Outlook 2007 store the AutoComplete list in the .nk2 file.

To copy the AutoComplete list in Outlook 2007, see Import or copy the Auto-Complete List to another computer.

How to remove AutoComplete list entries one at a time

To remove entries from the AutoComplete cache one entry at a time, follow these steps:

  1. Open a new email message.
  2. Type the first few characters of the AutoComplete entry that you want to remove.
  3. When the entry appears in the list of suggestions, move your mouse pointer over the suggestion until it becomes highlighted, but don't select it.
  4. When the X icon appears next to the highlighted suggestion, select X to remove the entry from the list, or press the Delete key on the keyboard.

Selecting X will prevent that entry (name) from appearing in the AutoComplete list again but won't remove it from your account. This entry may still appear in other areas in Outlook (such as search boxes).

Note

If you send a person a new email after you've removed their name from the AutoComplete list, their information will be added back to the list.

Issues with the AutoComplete cache

This section describes known issues that can occur with the AutoComplete cache. The AutoComplete cache can become corrupted over time and may not save new entries. If this happens, you can try to remove individual entries from the list. To do this, see the How to remove AutoComplete list entries one at a time section. If that doesn't resolve the issue, the whole AutoComplete list can be reset. To do this, see the section titled 'How to clear the whole AutoComplete list.'

How to change the limit for the AutoComplete list

Because this configuration is untested, we don't recommend it. If you have a larger AutoComplete list, you could also lose a larger number of cached entries if your AutoComplete cache becomes unusable because of corruption. Given this disclaimer, you can use the following registry data to increase the AutoComplete list limit in Outlook.

Important

This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry,see How to back up and restore the registry in Windows.

  1. Exit Outlook.

  2. Start Registry Editor.

    • In Windows 8.x, press the Windows key, type regedit and then press Enter.
    • In Windows 7 and Windows Vista, select Start, type regedit in the Start Search box, and then press Enter.

  3. Locate and then select the following registry subkey:
    HKEY_CURRENT_USERSoftwareMicrosoftOffice<x.0>OutlookAutoNameCheck

    Note

    The placeholder <x.0> in this registry subkey represents your version of Microsoft Office. Use the appropriate value from the following list.

    Outlook 2016 = 16.0
    Outlook 2013 = 15.0
    Outlook 2010 = 14.0
    Outlook 2007 = 12.0
    Outlook 2003 = 11.0

  5. Type MaxNickNames, and then press Enter.

  6. On the Edit menu, select Modify.

  7. Type the new value for the limit, and then select OK.

    Note

    • Make sure that you type the number in decimal form. That is the correct form in which to type the number.
    • Try increasing the limit by only a marginal amount to test the new limit. For example, to create a 20 percent increase in the limit in Outlook 2013, you would specify 1200 for the MaxNickNames value.

  8. Exit Registry Editor.

  9. Start Outlook.

Note
