Windows 10: Unable to move Outlook 16 .OST file location to D:\ drive!

Moving email accounts from old pc Windows 7 Outlook 2007 new pc with Windows 10 Pro and Office 365 Personal for a local church.
I have been able to move the Data File for two Outlook.com Data Files to the D:\Users\username\Documents\Outlook Files folder successfully but trying to move the Data File for a BT Mail IMAP account is proving
challenging.
I have followed instructions in https://www.slipstick.com/outlook/config/how-to-move-the-imap-personal-folder-pst/#reuse
which states “Use the ForcePSTPath regedit to change the default *.pst path and in Outlook 2013 and newer, the IMAP *.ost path. The ForcePSTPath key will recreate the pst files used by IMAP accounts in Outlook 2010 and up but not in earlier versions.”
All steps below have been carried out with Office 16 closed and adding the email thru Control Panel > Mail > email accounts > Manually as I have to enter the Incoming and Outgoing mail servers, New Outlook Data File checked ports etc. I have tried to change the location for the data file location using the ForcePSTPath for a new (BT Mail) IMAP account without success;
it still stored the data file in C:\Users\Username\AppData\Local\Microsoft\Outlook\email address.ost file.
I removed the IMAP account and deleted the data file saved in C:\Users\Username\AppData\Local\Microsoft\Outlook\email address.ost file. I altered the location using the ForceOSTPath method and still the data file is saved to C:\Users\Username\AppData\Local\Microsoft\Outlook\email address.ost file as shown below(red boxed)




But in Outlook the BT email account appears as shown below plus a D:\Users\username\Documents\OutlookFiles\... ;



I need to move the Data File for the IMAP account to D:\ drive as my SSD has a small capacity.
Any ideas on how to move the .ost file to the D:\ drive?

Changing the File Type on an Outlook *.OST file.

I did a stupid thing and inadvertently changed the file type of an Outlook 2016 OST file to a PDF file. I have tried to change the type of file that *.OST is used by to Outlook but Windows 10 does not let me. Does anyone have any suggestions.

Thanks

Okay, I'll create a folder in the D: drive as D:\Users\Church Administrator\Documents\Outlook Files\IMAP and create new ost file as per Move the OST and recreate the account method next week when I visit the office and post back with the result;

1. Open File, Account Settings or open the profile in Control panel, Mail.
2. Click New
3. Enter your username and password and let Outlook find your account information Select the Change account settings option, and then click Next
4. Click More Settings (1)
5. On the Advanced tab, click Outlook Data File Settings. (2)
6. If you want to create a new .ost file, browse to the new location, (3) D:\Users\Church
   Administrator\Documents\Outlook Files\IMAP enter a filename, and then click
   Open. Outlook will create the new .ost file.
7. OK your way back to Outlook then restart Outlook.

Thanks for all your help

 

Accessing Outlook Data Files (.ost) from MAIL App after W10 upgrade

After upgrading to Windows 10... I can't figure out how to ADD Data Files within the MAIL app. I have SEVERAL very old .ost files that I keep some old mail folders in that I used to be able to add to the FILE FOLDER list in Outlook. I can't seem to figure
out where to do that in the MAIL app.

Any Suggestions?

Thanks,

Kenny
