I was just sent an invite to a recurring meeting. I want to propose a new time, but only Accept, Decline, Tentative and Respond buttons show on the ribbon.

I then added all three Propose New Time icons to the Quick Access Toolbar, but they are gray.

Why can’t I propose a new time?

When I access a shared Contacts folder from another user, I don’t see the “Outlook Address Book” tab in the Properties dialog of that folder.

How can I add a shared Contacts folder as an Address List to my own Address Book?

When I start Outlook, I get an “Internet Security Warning” dialog box with the message;

The server you are connected to is using a security certificate that cannot be verified.
The target principal name is incorrect.

I clicked on “View Certificate” and installed the certificate, but I still get this dialog each time I start Outlook.

Clicking “Yes” each time allows me to use Outlook as normal but how can get rid of this dialog?

When I open a message in Outlook Web Access (OWA) via a double click or create a new message, this message is opened in a separate window.

This basically “detaches” it from the current browser window and makes it hard to find back when I switch between applications.

Can I open it in a new tab instead so that I can group all my OWA activity together?

I’ve created a list of Categories in Outlook which I don’t like to lose so I thought about backing them up. Unfortunately I couldn’t find an export/import option for this.

How do I backup my Categories and, if possible; can I also copy or restore them to another mail profile?

I’m getting the same spam message over and over again even though I mark it as Junk each time. I expected that Outlook would delete these messages automatically after I delete a couple of them.

How can I train the Junk E-mail Filter in Outlook?

I organize my Contacts folder by category, and every category is expanded each time when I go the folder, no matter how carefully I compress the categories or arrange them.

Is there any way to keep these category groups collapsed?

I’ve tried a couple of times to create envelopes in Word for Outlook contacts (for which I’ve entered addresses) but every time I try I end up clicking around a lot without any satisfactory result.

This seems like a core functionality of Outlook though, which shouldn’t be too hard and quickly to repeat so I must be doing something wrong here.

Could you walk me through the process of creating envelopes?

Outlook can find emails with one or more attachments by specifying the “Has Attachments” option.

But how can I search for a specific type of attached file?
e.g. search for emails having .doc, .pdf, .xls or .zip files etc.

The following question was raised in responds to; Traveling between time zones

When I change time zones, I don’t want some appointments and tasks to be adjusted. For instance, I have a daily recurring task to take my medicine at 2PM and a weekly recurring appointment to hit the gym twice a week at 5PM. When I change time zones, they could suddenly fall in the middle of the night, which doesn’t make sense.

Can I create appointments and tasks with such “absolute times” so that they always happen at those times regardless of which time zone I’m in?
