Hi Agrippa,
Please remove the tick  "Mailbox Role" and click "Next" let us know what happens.
To uninstall any role remove the corresponding tick in the tick box and click next.

Thanks

I must add: the database no longer exists, there is no Exchange database.
MASEE Solution Guide - Technical Dept HeadCommented:
Do you have another exchange server in your organization/forest?

if not delete the database and uninstall.
if yes you have to move the system mailboxes to the newer version database.

Please check this as well.

Worst case you can delete the databases from ADSIEDIT
https://blogs.technet.microsoft.com/mukutdas/2015/09/11/remove-public-folder-using-adsiedit/
1.        Open Adsiedit.msc

2.        Connect to the configuration partition.

3.        Expand
CN=Configuration--> CN=Services --> CN=Microsoft Exchange  -->  CN=<Your Org Name>  --> CN=Administrative Groups --> CN=Exchange Administrative Group (FYDIBOHF23SPDLT)   --> Databases.

Open in new window


4.        Delete the appropriate database and uninstall.

Deletion from ADSI is not a recommended practice. Please be very careful.

Thanks
