Active Backup for MS365 - Missing folder in backup

[capncook]

Hello,

I have a RS3621xs NAS, running ABB for MS365.
I run backups for 3 MS tenants, and i wanted to restore some mail from the sent-items ("Verzonden Items" in dutch) folder for a user.

Looking at the MS ABB for 365 portal, for that specific user, all folders and e-mail exists, except for the sent-items ("Verzonden Items" in dutch) folder.
When i go back in time, it seems to have dissapeared on a random date - to never return again.

On 01-08-2023;

On 07-09-2023;

I have no idea why this happened. In MS365 the folder exists, having large amounts of e-mail in it.
It never was deleted.

Any ideas how to resolve this ?

Thanks

Guessing the task settings are covering this folder to begin with?

Im not sure i even can include/exclude folders.. But "Mail" is selected yes, other folders are updating fine. (continuous backup)
