I add links from onedrive. Everybody who has the link should be able to view file. But the other team members are declined while trying to view the file.
Sorry to hear about that trouble. Are your team members not seeing the file when they select the link in Trello, or do they not see the link formatted properly in the card?
If it's not available when selecting the link, I'd suggest checking that file's permissions once more. The link provided in the Trello card doesn't have any inherent permissions on it's own, rather that permission is set in OneDrive.
If the link isn't properly displaying, it sounds like your team members might not have their Trello account authorized with OneDrive. To do that, they'll want to open a card, select Attachments, and then OneDrive, which should prompt them to follow the authorization process.
If you had to thrive a new habit during a lockdown, what would it be? Trello
