I have Microsoft 365 Personal Office Product. My email previously went through Cox Communications but now they use Yahoo Mail, using IMAP. I am not using Exchange Account & my Calendar does not go through Yahoo.

I am having difficulty with "Outlook Calendar", it has disappeared as of last week. No .pst file for calendar. I believe I did an update for TEAMS last week. I had an IT professional here to look for the file. He suggested I write to you & try to figure out where my calendar is located. The calendar that is in Outlook now is old from 2024 & past. All I did was wake up & go to my pc to review my schedule, everything is gone. What happened, help!

    Hi @Debo

    Thank you for posting your question in the Microsoft Q&A forum. 

    Based on description, look like your calendar unexpected disappeared.

    First, I will need more information so I can assist you better.

    May I know which Outlook version are you using (New Outlook, Classic Outlook)?

    Please try sign in Outlook web to see if your calendar shows up there.

    FYI, Outlook cannot sync calendars from POP and IMAP accounts.

    Please clarify if the calendar has ever appeared in Outlook before, or it never appeared in Outlook?
