syncro outlook/gmail - files empty

Hi,

I use outlook 2021 to manage my gmail mailbox with the de GWSMO ap.

In Outlook I created many files that used to be synchronized with Gmail on my old PC.

when initalizing a new PC, the files have been created on outlook from gmail after syncrro but they remain empty with a message in each file saying saying that search found no message.

In the meantime the files on the old PC remains weel syncronised.

Thanls for your help.
