Open the Outlook Address Book from a Desktop shortcut

Address Book buttonAlthough you can create Outlook Desktop shortcuts to specific folders within Outlook, there is no command line switch to directly open the Outlook Address Book.

Especially in a corporate environment, having such a shortcut can be quite handy to quickly look up a contact in your Contacts folder or a colleague in the Global Address List (GAL).

Luckily, with a small vbs-script we can still recreate this “rolodex experience”.

Reply and keep original attachments

Reply with Attachments buttonWhen you reply to an email in Outlook, the original emails are not included. This is because it is assumed that the original sender still has access to the original attachments.

There are however various valid scenarios in which it makes sense to keep the attachments. A common scenario which would benefit from this, is in longer mail threads where Reply All is used and where new people are being added.

Although there are various workarounds available, having this option integrated in Outlook is more efficient.
