Dear @Aron O'Cass,
Thank you for reaching out to the Microsoft Q&A forum. I am happy to assist you.
Could you please confirm whether you are opening the file directly from a Teams channel or team within Microsoft Teams, or if you are opening it via SharePoint?
If the issue occurs when opening the file through SharePoint, it may be related to trusted site settings. Specifically, the SharePoint site may not be added as a trusted location in the Office application, which can prevent files from opening correctly. In this case, please try adding your SharePoint site as a trusted location by following these steps:
Open the Office application you are using to open the file (for example, Word for a Word document).
Go to File > Options > Trust Center > Trust Center Settings.
Select Trusted Locations. > Check Allow trusted locations on my network. > Select Add new location
Paste the SharePoint file or site link, then select OK to save the changes.
Then try open the file again to see if the issuer persists.
If the issue persists, it may be caused by a mismatch between the account signed in to the Office application and the account used to access SharePoint. To verify this, please open the Office application and go to File > Account, then confirm that the signed‑in account matches the account you use to sign in to SharePoint.
If the accounts are different, please add the correct account by following these steps:
Select File > Account > Choose Switch Accounts
Select Add Account
Enter the credentials for the account used to sign in to SharePoint and complete the sign‑in process

Hi, I am in teams and a teams site for a project in teams, I right click on the file to "open in app" so I can work on the file and edit etc. It fails to open with the error or if it by chance it opens constantly asks for sign in and won't save changes to the file
Hello @Aron O'Cass,
Thank you for providing the information. Based on your description, the issue may be related to an account mismatch between the account used to sign in to Microsoft Teams and the account(s) currently signed in to the Office applications. In some cases, having multiple accounts signed in can cause the application to be unable to determine which account should be used to open the file.
To help isolate this issue, please try the following steps:
Back up your account information
Before proceeding, ensure that all account details (such as user ID, email address, and credentials) are securely saved in a trusted location.
Sign out of all accounts in the Office application
Open the Office application used to open the file (for example, Word for a Word document).
Select the profile icon and sign out of all currently signed‑in accounts.
Sign in with the same account used in Teams
Sign back in using the same account that you use to sign in to Microsoft Teams.
Restart your device, then return to the file and select Open in app to check whether the issue persists.
Please let me know the outcome, and I will be happy to assist you further if needed.
problem still persists, I even asked my colaboratir who own the site to remove me and put me back in, didn't work either
Hello @Aron O'Cass,
Thank you for taking the time to review my previous suggestion and for providing additional details.
If the “Open in app” option is not available, I recommend first downloading the file to your local computer. To do this, please click the three‑dot (⋯) icon next to the file and select Download.
Once the file has been downloaded, please open the corresponding Office application (for example, Word or Excel), then navigate to File > Open, browse to the location of the downloaded file, and select Open to access it.
If the file still cannot be opened using this approach, please capture a screenshot of the issue or any error message displayed and share it with me via private message. This will allow me to review the behavior more closely and provide more targeted guidance.
Thank you for your cooperation. I look forward to your update.
