"Error 403: disallowed_useragent" when trying to sign in to Dropbox to access Excel file
Please help.
I'm using a Pixel 6 with Android version 12 updated 7/5/22.
I was trying to open an excel file on Dropbox with Excel.
It then brought me to this page saying "Sign in to Dropbox to link with Microsoft Office Integration" in the Excel app.
I chose "Sign in with Google" since that's how my Dropbox was setup.
After entering my email and password, it told me "You do not have any security keys registered for this account.", so I chose "Try another way".
Then I chose "Tap Yes on your phone or tablet", which then caused Google to send me a notification asking "Are you trying to sign in?"
I chose "Yes, that's me.", then the Authorization Error page showed up, with the following message:
Authorization Error
Error 403: disallowed_useragent

Sorry I don't know what happened, but when I tried the same thing today, it did not ask me what app to open the file with and directly opened it with Excel.
It asked me if I would like to link Dropbox to either Microsoft or Google (I didn't read carefully), then the file opened without much problem.

Hey Jojo26, thanks for reaching out to our Community.
I've found this article on the Microsoft support page, can you take a look and let me know if it helps at all?
Thanks.

It asked me if I would like to link Dropbox to either Microsoft or Google (I didn't read carefully), then the file opened without much problem.I am having the same issue. New phone. Dropbox app working on the phone, successfully connected in my dropbox account which was set up via a Google account. However, when I enter Office and try to add a place (and then, Dropbox) I have to login again and get the error. Tryied to reboot, clear cache, pray, nothing is working
This is a new phone, all apps are the last version (I checked). Funny that dropbox app connects. Office also connects and also works fine to open files on other folders. Chrome is also last version. The problem occurs when I try to open a file on a dropbox folder, it requests that I connect AGAIN to dropbox (apparently it does not see I am already connect via the dropbox app). This also happens if I try to go to Office and "add a place" to add dropbox folders. So then it requests AGAIN tat I connect on my dropbox account. For some bad integration reason in both cases, when I click on use google to connect it requests I type user and password, and in both cases I get the same message. To check it out I did everything in the older phone, and the same problem occurs. In none of the cases Chrome seems to be used, but just confiming, Chrome also is the latest version in both phones.

Hi dechiaroma, could you let us know what plan you're on currently according to this page on your account?
- I think the problem is android 12.

Hi anurtd354,
Thanks for visiting the Dropbox community. Sorry to hear you are having this issue. I can see that MrBeanley was also experiencing something similar and seems to have found a workaround for it. Have you tried the method he outlined above? Please let us know if this works for you too.
Thanks again and have a great day!

- Hi,
after I installed Microsoft Excel and let a few days,
I just tried it again and it worked
I dont know why that it worked.
Maybe something looks like a glicth server between Microsoft and Dropbox when someone who has android 12 devices.
I am unable to edit dropbox documents on android (through the Dropbox app and through the Chrome browser). It keeps giving an Authorization Error 403 disallowed useragent, when I try to open the Dropbox document with Microsoft Word app. Would appreciate some help please.
I've attached a screenshot of it.

- Thanks Nancy
I navigate to an excel file through the DB app on my phone. Instead of opening the file with the DB app I select to open with MS excel to access the full excel features. Before it lets me open it asks me to connect DB to excel. I select to sign in with Gmail which is how I sign into DB. That’s when I get the message.
