Unable to repair or restore global inbox database

I am unable to add new group or add new files to my inbox. After running “Verify and Repair Database”, i got the following message “Found 427316 inconsistencies, 0 invalid filenames, 0 missing and 3 orphaned files.”.

I tried to “Restore Database” and " Rebuild Database" but these options were greyed out.

Please advise how i can get it working again. Thanks

Is File > Rebuild Database available after restarting the app? Is there enough disk space left on the startup volume?

It is due to insufficient space. I rebuilt the database and it is working fine now. Thanks for your guidance.

Thanks for the follow-up, glad that this issue could be resolved.
