Hello,

I am an Office 365Pro user, with two mailboxes synced into my outlook. The gmail based mailbox tops out at 50GB, but I'd need a 150.

Added the right DWORD files (MaxLargeFileSize 0x00025800 (153600) and the warn file) to here:

Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\PST

Yet, after multiple restarts, the .ost file remains topped out at 50GB.

I've also added the same files under 12.0\Outlook\PST and simply Office\Outlook\PST, just in case. Is there anything else I can modify to make it work? The Microsoft Exchange mailbox does go up to 100GB

Do you guys have any recommendation?

Thanks,

Peter
