Delete automated profile deletion

Hi,
Working with a Microsoft Exchange account, I have to use another account (a Microsoft 360 one) to benefit from important features from Hubspot : agenda synch…
I am not using this second profile which mainly allows me to connect my Outlook agenda with meetings features (that Hubspot doesn’t allow with a microsoft exchange account).
However, Hubspot considers my Microsoft 360 account as unused. And every 30 days automatically deletes this account.
Thus I lose my agenda synch which is quite a big problem for me as I use it in landing pages, emails and so on.
Would it be possible to stop deleting this secondary account or open every features to Microsoft Exchange users?
Thanks
