Using New Outlook on Windows for personal email, calendar, and contact management
Hi Rita Rita1
Good day. Hope you are doing well.
Thank you for posting back. I understand that you have been able to import the pst file from old account to your new business account. However many emails are in the Deleted items folder and your contacts & calendar are missing.
Regarding the missing contacts & calendar, please open the PST file in Outlook to see if the contacts and calendar folders are contained in the PST file. To do this, go to File > Open & Export > Open Outlook Data File
If the contacts and calendar are present in the PST file but not imported, try re-importing the PST file and ensure you select the option to import contacts and calendar items. Otherwise, please try to re-export the contacts and calendar from your old account.
For emails misplacement, given the complexity of the issue, it is suggested to escalate this matter to Microsoft technical support team directly. Microsoft's back-end support team can check the advanced logs and investigate the situation further. Due to the limited permissions and access resources of our community moderators, we are unable to collect certain types of registration information in public forums for this reason and for the privacy of our users' data.

Your kind understanding and cooperation are greatly appreciated.
