Outlook send/receive issue after moving pst files to Drive D

I need some advice, as this issue is driving me pretty crazy and the solutions I've found online so far don't seem to work or have negative downstream consequences.
Win 10 (oem), v.1903
Office 2019 Home and Business (oem)
Internal Drive C: program files (but the oem install has the Documents folder on Drive C too for some reason)
Internal Drive D: data files
Background

1. After activating Outlook 2019, Windows automatically placed each pst file in C:\\Users\Username\Documents\Outlook Files\emailn@xyz.com. Instead, I would like to store each Outlook pst file (have multiple email addresses/pst files) in a Documents folder (or some other folder) on Drive D.
2. To move the original Documents folder from drive C to Drive D I closed Outlook, right-clicked the original Documents folder and used the Properties/Location tab to move it to a new Documents folder I had previously created on drive D. That step seemed to work correctly, and each pst file was now in the new Documents folder on Drive D.
3. After the folder move, I launched Outlook and used the resulting "Outlook can't find" popup to specify a new file path for each pst file. However, while I can see each new file path in Outlook's Account Settings, it throws send and receive error messages (e.g.: "Sending reported error (0x8004010F): Outlook data file cannot be accessed") and won't send or receive for each account. This continues to happen after closing and reopening Outlook.
4. I moved the Documents folder back to where it was on drive C. I tried this several times, using the Outlook error popup to try to remap each email account to the new Documents path on Drive D.

Bottom line is that this Outlook send/receive issue is also preventing me from moving my Documents folder to the D drive where I want it, because when I move it, it messes up Outlook.
Question

• After I move each pst file and specify the new file paths in the Outlook popup, how do I get Outlook to send/receive for those email accounts?

Thank you in advance.

If you're wanting the move to D to serve as a backup, consider simply copying from C to D 2-3 times weekly.
Many Microsoft and 3rd party programs do not take kindly to being "forced" away from their respective default settings.

I don't have Outlook configured on this PC and admittedly haven't ever used it with Windows 10, however; I've used it almost daily with every other OS since Windows 95. As far as I recall, I have always kept my pst files on another drive or at the least another partition. It rarely gave me any grief once I figured out what I was doing.

Hi Roland, thanks - "New Method" - I went down that rabbit hole yesterday - I searched and there is no "Mail" icon in my control panel (also found advice online to run "C:\Windows\SysWOW64\control.exe mlcfg32.cpl" from the Run app as a workaround, and that didn't work either).

Make sure you are in classic control panel, NOT settings app. Type "control" (without quotes) in Run app and then type mail in the "Search Control Panel" box. Following is result I see, and I can select "Data Files".


Do you not get the same result?

I recall seeing that window after right-clicking the Outlook icon while Outlook was NOT running. Of course, this is ages ago, likely with win7.

First, thank you to everyone who posted on this thread with helpful advice.

I just want to report on what I learned over the past several days from Microsoft.

It appears that Outlook (2019) will not function correctly if the POP3 .pst files reside on a separate internal Drive D. While one can get an Outlook account to display a Drive D .pst path, send/receive for that account will throw an error. The .psts need to stay in the main default drive and path, which on my computer is C:\\Users\Username\Documents\Outlook Files\emailn@xyz.com.

If Office is installed through the MS App Store, there will not be a Mail icon in Control Panel. That's why there was no Mail icon in my install. If Office is activated from an OEM desktop version, the Control Panel/Mail icon and functionality will be visible. Warning: for certain OEMs with the desktop Office product key installed (because you purchased the desktop version with the computer), don't click on the big orange "Office" tile that you see when you click on the Start icon. Check with the OEM first on how to activate the desktop version (some of them send email instructions, so check there too).

The second-tier tech rep recommended adding any future new accounts using Control Panel/Mail (in my case: "Mail (Microsoft Outlook 2016)" (even though it's Outlook 2019)).

Am relieved that Outlook is working now, and again thank you to everyone.

Roland, agreed, am backing up to an offsite service.
