My outlook for Android app is having issues

Question

My outlook for Android app is having issues

Phil Vanderloo 20

I've had outlook as my default email app on my phone for several years.

My main email account is not an outlook account but a comcast.net account.

Out of nowhere, when I open the outlook app, it's asking me to sign in. After entering my credentials about 40 times I was finally signed in. Then the next time I open it it asks me to sign in again. I know my password is correct but I have to enter it a ridiculous amount of times before I get in. Everything is fine on my pc.

How can I end this nightmare?

Thank You

Hi @Phil Vanderloo

Thank you for posting your question in the Microsoft Q&A forum.

I totally understand how frustration it must be for you. It messes up your workflow and time-consuming.

Let's try with some basic troubleshooting steps.

Clearing app cache and data in Settings > Application > Outlook
Reinstalling Outlook or update to the latest version.
Reset the account in Outlook Settings > Account

Please try let me know if it works for you, if not, we can try another approach.

Thanks for your cooperation.

Same issue here; wondering if it isn't connected to yesterday's Android app update...

St John's Church, you may be onto something. I went into Settings-Software Update on my phone and update status is "Failed - August 27, 2025 at 3:09AM, Error Code 555" There's an option to install another update; however, not sure I want to risk messing up my entire phone. Right now, like the other posters - only Outlook Email isn't working.

Same issue here...."Your mail server certificate is invalid. Would you like to log in anyway?" and I enter an endless do-loop

I didn't do anything except for eat a bag of chips and a piece of cake and mine works now. It's been fine for the past 15 minutes. I hope the rest of you have the same good luck. (I use Outlook with a comcast email address on a Samsung Galaxy phone.)

Intel. No really it was a bag of Panera kettle cooked potato chips.

Mine also seems to be back to normal (fingers crossed). No chips involved.

Good luck, Phil. Mine has been working for over a half hour; hopefully yours resolves.

Thank You. I keep checking but at least I'm able to get and send emails through my phone's native email app. and without the annoying Ads I might add.

Hi @Phil Vanderloo

Thanks for updating your status.

If it doesn't set up automatically, please try manual settings.

Please double check if you input the right port in this comcast official document.

Set up your Xfinity Email address with an email program - Xfinity Support

Authentication mentioned that you should use your comcast password.

Also ensure this is enabled. It might be accidentally turned off.

Turn your access to third-party email programs on or off in Xfinity Email - Xfinity Support

Please try and let me know.

I'm looking forward to your reply.

Hi

Hi @Phil Vanderloo

Thanks for your update.

For this specific issue, my suggestion is raising a support ticket via Help & Feedback.

If you cannot log in, you can do it via Outlook Web version.

I had already removed the account and reinstalled it. Didn't solve the issue. Per your advice Jayden-P, I uninstalled outlook and re-installed and now I seem to be having problems with the setup. I would have thought that would be automatic?? Not sure on the passwords, (are they to be my server password or my outlook password?) either way neither are working.

I duplicated the port settings with my pc port settings, entered the password incoming and outgoing and I am unable to sign in.

It sounds like your Outlook app for Android is facing some issues. You can try the following quick fixes:

Update the app – Go to the Google Play Store and check if a new version of Outlook is available.

Clear cache & data – In your phone settings, go to Apps > Outlook > Storage and clear the cache or data.

Check internet connection – Make sure your Wi-Fi or mobile data is stable.

Re-add your account – Sometimes removing your email account from Outlook and then adding it back solves the problem.

Reinstall the app – Uninstall Outlook and reinstall the latest version from the Play Store.

If the issue continues, you can also contact Microsoft Support for further assistance.

I gave up. Way too much time spent trying to fix this one. I am using the native email app on my phone and everything is fine now.
