Hi,

If it is a calendar then you might have taken out PST.

If you have already configured Outlook for O365 mailbox, then simply attach the PST for calendar and drag and drop all contents to the O365 mailbox default calendar.

Hi,
It's not pst. It's olm file because I got Mac book.

Then I got office365 in new profile.
Then I imported the calendar into the new profile, it's showing under "under my computer" but from there how do I drag and drop ? I tried it did not work. I tried "move to " option nu right clicking - did not move or copy either
Saif ShaikhServer engineer Commented:
You need to convert the olm file to PST.

There are many free tools available on google.

Once it's a PST then you can attach the same in outlook and drag and drop calendar items.
