Whenever I send an attachment through Outlook, the recipient receives the email without the attachment although they sometimes say that it got renamed to winmail.dat.

It happens to all attachments regardless of who I send it to and the format of the file (e.g. PDF, Word, jpg, etc). If I send the same attachment through web mail or from another computer, the attachment remains intact and is received in the email.

I've tried turning off my anti-virus program but that's not made any difference, so I'm assuming the issue must be within Outlook itself.

After an update of Office, Outlook now displays the navigation buttons for Mail, Calendar, Contacts, Tasks, etc… on the left side next to the Folder List.

These Navigation buttons used to be displayed within the Folder List at the bottom.

Where is the option to move the Navigation buttons back to their original location?

One of my accounts in Outlook went from “Trying to connect” to “Need Password” in the Status Bar.

However, pressing on the “Need Password” icon doesn’t bring up the dialog to enter my username and password. The dialog isn’t hidden behind Outlook either, although sometimes it looks like it opens and closes really fast again.

No dialog comes up either when clicking on the "Type Exchange Password & Connect" button nor when the Notification comes up that Outlook needs your password.

How do I get myself in a Connected state again?

In the calendar view of Outlook 2010 and also in Outlook 2013, there is a Navigation Pane on the left side with a Monthly Calendar shown at the top. If you select the first week of that calendar and some days of that week are in the previous month, that monthly calendar automatically switches to the previous month.

This behavior is irritating as it is switching to another month. How can I make Outlook stay in the current month?

I tend to leave my messages open in their own window for various good reasons at that time. However, after a while, it doesn’t make much sense anymore to leave them open and I wish to close them all but not Outlook itself.

Right now, I close them one-by-one which is rather cumbersome or completely restart Outlook as that is sometimes quicker but I feel like that is a bit of overkill.

Can I somehow close all open message windows but leave open similar to the “Close other tabs” in an Internet browser like Internet Explorer and Chrome?

The weather doesn’t really seem to play along this Summer; it’s either lots of rain or draught, no sun at all or a bit too much sun and of course, for some of you it’s Winter now! But even though the weather might be a bit gloomy, it doesn't mean that your Automatic Replies (OOF) have to be the same.

While you can maintain a serious business style OOF message for the outside world, how about a more cheerful notification message for your colleagues hard at (doing your) work?
