How to quickly unblock unsafe attachment types in Outlook?
If you have received some emails with attachments whose extension is msi, exe, etc. in your Outlook, you will get a warning message “Outlook blocked access to the following potentially unsafe attachments” as following screenshot shown when you open the massage. Outlook will consider these types of attachments as unsafe information by default. But, how could you set these attachment types as safe files and easily view or download in Outlook?
Change default attachment size, saving folder / add blocked attachment extensions in Outlook:
With Kutools for Outlook’s Attachment feature, you can increase the attachment size as your need, and change the default folder for saving attachments, at the same time, you can add some extensions that Outlook blocks.
Normally, you can add the attachment extensions into the regedit to allow these specific types of attachments to be safe. Please do as follows:
1. Make sure the Outlook is closed.
2. Then click the Start button of the computer, in the search box, please type regedit, see screenshot:
3. And then press Enter key, in the popped out User Account Control dialog, click Yes button to go to the Registry Editor window, in the Registry Editor window, please locate the following key:
(1.) Outlook 2010:
(2.) Outlook 2013:
(3.) Outlook 2016:
4. After going to the Security step by step, then click Edit > New > String Value, see screenshot:
5. And then rename the item you have created just as Level1Remove, see screenshot:
6. Then double click the created value and enter the extensions including the “dot” that you want to open in Outlook. For example: .exe, see screenshot:
Tips: If you want to enter other extensions, you need to separate them by a semicolon like this: .exe;.bat;.url;.msi.
7. Then click OK and close the Registry Editor, now, launch your Outlook, the attachments which contain these specific extensions aren’t blocked by Outlook anymore. See screenshot:
Note: If you want to block those extensions again, you just need to go to delete the Level1Remove value you are created in the Registry Editor.
If you are confused by the above method, here, I can talk about an easy way, with Kutools for Outlook’s Safe Attachment feature, you can quickly set the safe attachment extensions you need.
