Problem with sort email sent

Hello

I've an office 365 account. I've lost 2 months of email from the sent folder.

Restored via Synology Active Backup 365.

After restoration I've a view problem:

- Via outlook all it's ok

- Via web email are not sorted by date but the email restored has different date.

I've read a problem of Synology resets time stamp https://community.synology.com/enu/forum/1/post/132938?page=1&sort=oldest

Have you ever this problem? Can I select different time field to sort the email via web ?

My best regards
