GWSMO - Modifying PST File Size in Registry Does Not Work in Windows 11 Anymore

[Jayce]

Ever since the Windows 11 Update the PST File Size Override option in Registry Editing for Google Apps Sync does not work. It causes outlook to quit syncing.

I have spoken to numerous tech support at Google who were unable to solve this issue.

Please help.

This feature used to work but does not anymore: https://support.google.com/a/answer/1041455?product_name=UnuFlow&visit_id=637878150698117541-2970721...

Did you get a response to this? Got a few mailboxes over 50gb and causing me a headache

No, unfortunately Google could not help, at any level of escalation on many many calls. However, I did find one size setting that worked for me. Each time I called Google they said the MaxStorePstSizeMegaBytes value data should be however many megabytes you want your mailbox to be, in hexadecimal base. I ignored their advice and set it to 40000 as a decimal base instead. And that has allowed my mailbox to function with around 48 to to 49 gb in size.

I found out that when I pasted the EmailSync key, it pasted a space , ant that made the software ignore it
