Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi kgolubic,
Please follow the steps below to first set up the files storage space in OneDrive for Business and then try accessing in Planner:
- In Office 365, go to OneDrive for Business.
- Open the ‘Groups’ in OneDrive for Business which is connected with the plan where you cannot upload attachments.
- Click on the ‘Plan’> OneDrive for Business will ask to wait, while it configures your group files.
- After you see the message ‘Ready to go’ in OneDrive for Business, go to Planner and you will get the options to attach a file.
If the steps above don’t work for you, I would like to collect the tenant information to check your account. I’ve sent you a private message to collect this information, please access it via this link.
Thanks,
Neha
