How do you turn off the Outlook email sidebar in Microsoft Edge?

Microsoft have recently made a change to how internet links open from within Outlook. The link now opens in Microsoft Edge and also shows the email content in a box to the right known as the side pane.

Some people like it, some don’t. Here’s how to turn it off.

  1. Open Microsoft Edge and click the ellipsis button (top right)
  2. Go to Settings (cog icon)
  3. Under the Settings heading click “Sidebar
  4. Under the heading “App and notification settings” then sub heading “App specific settings” look for Outlook and click it
  5. Turn it off by clicking the “Automatically open Outlook email context in the side pane” toggle.

Outlook keeps asking for password… Using Office 365 but on-premise exchange?

Starting in Outlook 2016 version 16.0.6741.2017, Microsoft has enabled a new feature called Direct Connect to Office 365. What this feature does is connect Outlook directly to Office 365 if Autodiscover is not working. This is great feature but a network hiccup may cause your mailbox to connect to Office 365 rather than your on premise Exchange, even with a valid autodiscover record.

For Direct Connect to take effect the user must have an active mailbox on Office 365 with a valid license. Typically Direct Connect would be a neat feature unles you are in the middle of a migration to 365, but a network hiccup could incorrectly connect you to 365 even though you havent completed your migration yet.

During 365 migrations deom Hosted Exchange or On-Premise, we recommend disabling this option from the user computer registry:

You can stop Outlook from checking Office 365 for settings by setting a registry key.

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover
DWORD: ExcludeExplicitO365Endpoint
Value = 1

Then restart your computer and it should stop trying to connect to Office 365. When you are ready to flip the switch on your migration, remove this registry key.

Heres a great article describing the whole thing in more detail…

Outlook 2010 signature button not working (64-bit)

I recently removed Office 2010 (32-bit) and installed the 64-bit version. This introduced the problem where my signatures in Outlook were no longer being added to emails.

I fully understand the process of creating signatures, how they work, where they are saved etc so off I went to File > Options > Mail > Signatures

My issue was that the “signature” button, when pressed, wouldn’t open the window with all the options for creating and editing signatures. Clicking it just did nothing!

After a bit of searching I found the following solution…

Use “regedit” to change the “(Default)” and “LocalServer32” values in each of the keys below to C:\Program Files\Microsoft Office\Office14\Outlook.exe

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\{0006F03A-0000-0000-C000-000000000046}\LocalServer32

-and-

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{0006F03A-0000-0000-C000-000000000046}\LocalServer32

Once the keys have been changed, launch outlook and the signature button will work again allowing you to change your signature preferences.

Note: The above fix will also work for the 32-bit version of Outlook, just change the C:\Program Files\Microsoft Office\Office14\Outlook.exe to C:\Program Files (x86)\Microsoft Office\Office14\Outlook.exe
