Decryption fails running iOS 14.2
Just updated iPhone and iPad to iOS 14.2. Now, trying to open an encrypted file, it tell me "Decryption Failed. Null" If I open with Excel, it works fine. Anyone else having this issue?
I also have success opening an encrypted file within Dropbox after updated 14.4 IOS update. Thanks for everyone's help and input.
After an update WORD and EXEL by Microsoft, the problem has been solved.
- If you mean version 2.43 from a day ago then I have this installed but the problem remains
Laincars is correct, the issue is not resolved!
Sorry, the MS update did NOT resolve the problem for me. I updated my MS Office over a week ago. The problem really seems to be the iOS 14.2 update. Everything was working fine until I updated my iPad and iPhone. Immediately aferwards I had the problem with encrypted documents not opening in DropBox.
I have all my passwords in a file in dropbox, till a few day ago I could open the file through a password without problem on the iphone (IOS 14.2), lately I receive the message "decryption failed null" I then have to open the original word file in dropbox and it functions correctly, what is the cause of this problem?
I have the same issue. I am on iPhone 8 running iOS 14.2.
Get the "decryption failed (null)" message, and it looks like an iOS issue. To overcome the problem, I installed Excel, signed in and click on the "Open" blue button on the "encryption null" screen on Dropbox and it opens the relevant file (Excel, Word, PowerPoint) in the Excel, Word or PowerPoint app. Enter the password and it unlocks the file.It's not seamless as opening it from the Dropbox app, but it allows to view (and edit) the file to say the least.
- Hi
Issue just happened.
I can access all spreadsheets on all other devices.
On iPhone I can only access unprotected excel. The protected ones says failed (null).
Please help :-)- Lusil

Hey MissMC, thanks for checking in.
I moved your post here, where other users have also described this issue.
Have a look around at what is mentioned, and let me know if you'd like to further investigate this with us.
Also, Deacon Art, I'd be happy to send you a ticket if you haven't gotten in touch with our Support team yet.
Just give me a nudge, thanks!
- Sorry, I really don’t understand why Lusil or Daphne cannot be proactive and submit the trouble ticket themselves to work with Apple to get this resolved. We know it’s a problem. Many of us have described having the same issue, gave the steps to reproduce the issue, and it was reported six days ago. All the information for Dropbox to start investigating is already here.
Hi, I have same . I have similar problem after update to iOS 14.2. Anybody has found solution?
- Yes. I assume you have excel (office 365) also installed on your phone. When you get the null error message select the icon at top righthand side of screen. Its the square with upward arrow. You should then see excel as an option. Select this, enter file password and it works fine. Same for pw protected word files.
Thanks - this works fine
- My situation was the same as JohnK2 experienced
- I tried an experiment. I put 2 excel spreadsheets on Dropbox. 1 of them I password protected, the other one I didn’t password protect. I was able to open the one that I didn’t password protect, but was unable to open the one that was password protected. I am able to open the password protected one on my computer, but not on my I-phone
The Excel Workbook will not open if it is passworded. Receive the same "decryption failed <null>" error message.
Excel and Word both work for me. Just Dropbox won't open an encrypted file. So, I click on the "open" button after I get the "Decryption Failed" and it takes me to Microsoft Word or Excel.
- Hello everyone, you will probably get better support from the Apple forums like: https://discussions.apple.com/thread/252020203. Seems like someone was able to open a case for this exact issue from Apple. Another mention saving the file in the older 1997-2003 format works, but I have not tried this.
Hopefully a fix will be made sooner than later. The workaround right now is to install Microsoft Word/Excel apps on your iPhone so that you have the option to open those password protected files from dropbox when decryption fails. An blue “Open” button appears at the bottom of the file and clicking this will take you through to the Word/Excel apps. You will have to enter your password again in the apps, but this will allow you to access the file successfully.
I can assume from reading other posts here that the reason that we cannot open/create a ticket for dropbox to even investigate is because we have a basic plan and dropbox will not help us without a ticket. Thank you all for reporting having the same issue to try and help us make the case even though Dropbox seems to have not taken the next steps to investigate further due to lack of ticket. We did our job reporting it.
- Hi John. I have the same error message while opening Excel files with my IPhone 11 after installing new updates . How did you fix this problem?
- Really don’t know what to tell you. In Excel or Word, I’ve always been able to open encrypted files. My problem, after upgrading to iOS 14.2, I can’t open them in Dropbox, where they are stored. I simply switch to Excel or Word and sign in my password.
- Same problem, also with Excel files in Google Drive.
So I think this is a Apple problem.
Hopefully they get this fixed soon :-)Here's more breaking news for everyone. Just downloaded Big Sur to my Mac and guess what? Dropbox is gone! You have to re-download the Dropbox app, then it works again. I have the feeling that Apple and Dropbox hate each other!
JohnK2 I am not surprised as there have been loads of articles about it not working with the beta version of Big Sur. As with any new o/s, unless I have to I think I will wait for an interim release of Bug Sur before taking the leap.
- Same here. However, “customer service” is silent, very frustrating.
Simply, go to the App Store and re-download Dropbox. No need for Customer Service.
