Microsoft Office Home and Business 2019 - Outlook PST max size

I'm running Windows 10. I purchased and installed Microsoft Office Home and Business 2019. Included in this suite is Outlook 2019. I have an Outlook.pst file that is now 1.81GB in size.

Now when trying to add or remove any items to/from my calendar, I get 2 different error messages. (see attached screenshots)

123_1

123_2

I have increased the WarnLargeFileSize to 4090445042 and MaxLargeFileSize to 4294967295. Even after increasing these file sizes I still get the same error message. I have restarted my computer, still same error.

My main question is why is the PST file limited to 2GB when I am running Outlook 2019??? According to Microsoft, the default PST max size limit is 50GB for this version!!!!

Any suggestions would be greatly appreciated.

Many thanks,

DaveW

    Hi @David Williams ,

    Based on my research, if you do registry for 2019 it is probably just the same only a slight variation in path like

    HKEY_CURRENT_USER\Software\Microsoft\Office\19.0\Outlook\PST

    According to Microsoft, Office 2019 and Office 2016 both have the same version: 16.0.

    My registry path shows HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\PST

    Hi @David Williams ,

    Sorry for my mistake, you were right.

    It is recommended you try to repair Office from Control Panel.

    Repair an Office application

    Then create a new profile form control panel and test if it works:

    Go to Control Panel > Mail > Show Profiles > Add, then readd your account.
