I declined a single meeting occurrence in Outlook. How do I get it back?

Solution 1:

I also could not "undecline," so I went to the sender's calendar, opened the item, and cllicked the button to copy to my calendar. A message popped up and said that to do this, I had to accept the meeting, which I did. Now it's on my calendar. Hope this helps.

Solution 2:

I just had the same need today (restore a declined occurrence of a recurring meeting not organized by me).

The below procedure worked for me (Outlook 2013):

1. Go to the calendar view
2. Double click on a remaining occurrence
3. Choose to open the "entire series"
4. Edit the "Recurrence" of the meeting (Ribbon > Meeting Series > Options > Recurrence)
5. Do a fake change (move something back-n-forth in the settings with no impact on the schedule so that Outlook "thinks" you have changed something)
6. Close the Recurence dialog (click OK)
7. "Save & Close" the meeting series

Now all instances should be back.

Solution 3:

None of the posted answers worked for me. Toggling the recurrence settings seemed promising, but I couldn't find those controls in Outlook web mail. What finally worked for me:

1. Completely delete the entire series from your calendar (don't send a response to avoid confusing the sender) - Note that merely declining and re-accepting is not enough, you must delete
2. Go to Deleted Items and find the original series invite
3. Accept the entire series again
4. The declined occurrence is now back, along with any other occurrences you had previously declined, so be sure to re-decline any future occurrences you still can't attend

Solution 4:

Try this (it worked for me).

Note: I did delete all instances of the calendar series before I did this. It is possible that is a necessary step.

1. Open your Deleted Items folder in Outlook
2. Find the original invite (if there were updates along the way, ignore those)
3. Right-click the original item and select Move > Inbox (you may need to select Move > Other Folder > Inbox).
4. When prompted to send this (for some reason it did not just move), email the appointment to yourself.
5. When the appointment arrives, click the attachment and select Copy to My Calendar.

Hopefully this will solve the problem for you. In my case it returned all instances back to my calendar and I could delete the one I intended to delete.
