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.

Check sending account address before sending email

Select Sending Account buttonNowadays, it is quite likely that you have multiple email accounts configured in Outlook.

Especially when working from home, you don’t want to end up sending your business emails via your private account or vice versa.

Also, when you have access to a Shared Mailbox or are a delegate for the mailbox of a colleague, you could find yourself inadvertently send from these mailboxes or forget to select it when needed.

By adding this simple VBA macro to Outlook, you can prevent sending emails from the wrong email address.

Add Teams, Skype, Zoom and other chat, call or meet now links to your signature

Chat & Meet in SignatureCommon signatures include a greeting, your name, your company name and possibly a website address and a phone number.

Since nowadays people contact each other a lot more via online meeting tools such as Teams, Skype and Zoom, you can also add special links which will allow the receiver to directly contact you via one of those methods as well.

With the use of recognizable icons, you can easily include these references without making your signature look huge.

This guide starts off with an example of a signature which is small but contains several instant communication links as well. After that, an overview is given of the instant communication links that can be used with commonly used IM and video conferencing clients.

Edit the HTML source code while composing a message in Outlook

Edit HTML Code buttonWhen composing a message in the HTML format in Outlook, the HTML code is automatically generated by the WordHTML engine. Unfortunately, Outlook does not provide a direct way of editing this generated HTML code.

With the EditHTML macro from this guide you can edit or completely replace the HTML of a message you are composing. This makes it much easier to make specific modifications or use the HTML code that you’ve created in another HTML editor.

This way you can make sure that your carefully created design, like for a newsletter, isn’t being modified again by WordHTML and remains compatible with other mail clients.

Recurring Email buttonDo you need to send the same emails on a recurring basis like daily, weekly or monthly? Sending out reminders, forwarding reports or the latest offers and prices can be a tedious task.

Outlook doesn’t natively have this feature but with some PowerShell code or add-in, it can be done quite easily .

The PowerShell code in this guide allows you to send an email template, that you’ve created in Outlook.

This guide contains step-by-step instructions to fully automate this process via the Windows Task Scheduler.

Scripts aren’t your thing? We’ve got you covered with some recommended 3rd party add-ins that can bring this functionality to Outlook as well.

Importing eml-files into Outlook

Import EML buttonIf you’ve ever used Outlook Express, Windows (Live) Mail, Thunderbird, Lotus/IBM Notes or basically any mail client other then Outlook, chances are that you have some eml-files stored somewhere as well.

While Outlook does support opening eml-files, it doesn’t offer a way to import them into Outlook.

Autodiscover: Some quick methods to get it working

Autodiscover.xml buttonThe Autodiscover service is a required service for Outlook-Exchange connectivity since Outlook 2007 and Exchange 2007 but for whatever reason, in some Exchange environments this still hasn’t been implemented correctly.

In some part, this was due to the fact that you could still get basic Outlook-Exchange connectivity by using some legacy Exchange 2003 RPC over HTTP dialog in Outlook. This (unsupported) method now no longer works in Outlook 2016, Outlook 2019 and Outlook for Office 365 due to the removal of this legacy dialog since Outlook doesn’t support Exchange 2003 anymore since Outlook 2013.

Unfortunately, this leaves up-to-date Outlook users disconnected when Autodiscover hasn’t been provisioned correctly by your company.

This guide contains some reasonably quick and easy and some less elegant methods for end-users but also for Exchange administrators to get your Outlook connected to Exchange again. All discussed solutions are fully supported configurations by Microsoft and do not require any changes to Exchange or the need for a new SSL Certificate.

Outlook can’t connect to Gmail: Password incorrect

Gmail buttonWhen configuring your Gmail account in Outlook (or other mail clients such as Thunderbird and Mail apps on (older) smartphones), you may run into continuous password prompts or sync errors.

This is because Google has turned off Basic Authentication by default for all new accounts and accounts which haven’t synced within the last 30 days and only lets you authenticate via the OAuth 2.0 standard.

As a result, you’ll get Send/Receive errors (0x800CCC0E) and could get prompted for your Gmail password again in Outlook and the login could fail even when you supply the correct password.
