If a file won't open, a few things could be wrong:
- The file owner didn't give you permission to open the file.
- You're signed in to a different Google Account.
- Someone removed your permission to access the file.
Get permission to open a file
- Open the file.
- On the 'You need permission' page, click Request access.
- The owner of the file will get an email asking for approval. After they approve your request, you'll get an email.
Tip: If you need access straight away, contact the owner of the file and ask them to give you access.
Try a different Google Account
If you have more than one Google Account, check whether you have access to the file with a different account.
To switch to another account:
- Open the file.
- On the 'You need permission' page, click Switch accounts.
- Sign in with a different Google Account and check whether you can open the file.
