Hi,

I encountered a seemingly ridiculous problem: 

I cannot insert any attachments into calendar events & tasks in
Outlook 2013 on a Win 8.1 machine. Outlook simply ignores CTRL-V paste actions with files and also all drag&drop actions with files. Does anyone have a solution or similar problems?

Outlook 2013 runs using an exchange server account (Outlook.com / Office 365) on the machine.

Even if there is a logic behind this behavior, Outlook should at least inform the user why it rejects inserting the attachment.

Inserting attachments into e-mails works fine.

All 3rd party add-ins have been disabled, to avoid interference of an add-in.

Hi,

This is an known issue, you can refer to the article that our MVP Diane Poremsky wrote:

Attachments are hidden in Outlook.com tasks and appointments

My opinion is, since Outlook.com calendar doesn't support attachments, this may be expected when you are using an Outlook.com account.

Feel free to let me know if I misunderstood anything.
