Default Calendar in Calendar when using MS Exchange email

Question

I use Outlook in Microsoft 365. I manage my own calendar and personal email, and connect to other email accounts via IMAP. Daily, I live in my inbox, and show my calendar in the to-do bar. Recently, I got a new email connection which uses Microsoft Exchange. While I could link this account fine for email, I found that I could no longer see my personal calendar in the to-do bar on my email screen....Outlook now defaulted to the Exchange calendar for my new connection, something that is useless to me. I have read that the to-do bar only shows the default calendar. I have tried changing the default calendar to my personal one, to no avail. I get an error message that says I have a PST file when it needs an OST file. So it seems like the fact that the new account is an Exchange account is running amok over my choice of default calendar and I can't change it. Does anyone know how to fix this?

Hi @Bob Belden ,

How did you change the default calendar? Please check if you follow the steps below:

• Click File > Info > Account Settings > Account Settings.
• In the Account Settings dialog box, click the Data Files tab. It shows you a list of all your accounts.
• Select the account in which you want your calendar information stored by default, and then click Set as Default.
• The changes are saved automatically. Click Close.
