Outlook Android “Sync Contacts” disabled for Microsoft 365 Business Standard tenant

Native Exchange setup hangs on “Retrieving account information”. No Intune license available (Business Standard tenant). How can I enable Outlook contact synchronization with Android Contacts?
Outlook Android shows different date on shared recurring appointments
My wife and I share our hotmail calendars with each other For recurring appointments that she creates only, on any Android device using the Outlook app, the appointment is always 1 day later. It is consistent The time is correct so it doesn't seem to be a timezone issue. In Windows settings, Android settings, and outlook.com settings the time zone is Sydney AEST I've resynced the android apps. But tbh it has affected me for years, and has followed me across devices Any ideas? Pixel Outlook v5.2618.2 Samsung Outlook v5.2618.2 ty!

Hello, I'm having issues signing on to outlook.com. Either through the app or web, keep getting an error. On the Outlook Mobile app, I get "An error occured during authentication". On the web I get the error below. Any suggestions appreciated.

Issues with outlook and teams on android
I'm not sure why, but since yesterday both Teams and Outlook have quit working. I have an S25 Ultra. I attempted to clear data and cache and do a fresh install. Outlook just hangs on a black screen with the notification "optimizing database," and Teams just indefinitely loads. I can't check my personal email or my work email and can't keep track of my work chats on Teams.Outlook for Android no longer grouping contact info...
I just started having an odd issue with all the contacts in the Outlook app on my Android phone... For contacts that have multiple contact information (ie: a mobile number, house number, and or email address) listed, the app is breaking out the contacts as separate contacts. Example: If I have James Kirk listed in my phone with a number of 555-111-1701 and an email address as jkirk@fakedomain, he no longer shows up on my phone as James Kirk; instead there are two contacts - one called 555-111-1701 and the other jkirk@fakedomain. Contacts show up correctly in the Outlook desktop app and on the Outlook website. If I modify or add contacts on the desktop app, the change is almost immediately reflected on the Outlook website. Some of the troubleshooting I've done already: Cleared the app cache from the Phone's settings Reset the account from within the app disabled/re-enabled contact synchronization Modified a contact on the desktop app to see if they'd re-sync correctly - had no effect Deleted the account (the contacts disappear when deleted, but come back janky when it's re-added) Uninstalled and re-installed the app Rebooted the phone (for good measure) uninstalling and re-installing the app seemed to fix the problem initially. Right when i setup the app again all the contacts came back looking correct. It's been several hours since I did this and i just took a look at my contact list and it's all janky again. It's not just a visual issue on the phone - it's affecting Contact synchronization with the phone's contact app, and everything else on the phone that relies on contacts. Any idea what's going on and how to fix it for good? TIAPersonal Microsoft account security code
Dear Microsoft Outlook Support Team, I am currently facing an issue while trying to reset my Outlook account password. I have forgotten my password and attempted to reset it, but I am encountering problems during the verification process. The system is asking for mobile verification codes multiple times, and I am receiving an error message stating that the service is not available. Because of this, I am unable to complete the password reset process. I kindly request you to assist me in resolving this issue and help me regain access to my account as soon as possible. Thank you for your time and support.It’s now easier to access iCloud Mail, Calendar, and Contacts in Outlook
We’re excited to announce that the new Outlook for Windows, Outlook for Mac, and Outlook for iOS and Android now support easier iCloud Mail, Calendar, and Contacts access. You no longer need to create and enter app-specific passwords to access your iCloud data in Outlook apps. Now using the OAuth 2.0 authentication protocol, simply sign in with your Apple Account to access your iCloud Mail, Calendar, and Contacts in Outlook. If you already have iCloud set up in Outlook, in the coming months you will be asked to sign in, which will reauthenticate using the new OAuth 2.0 flow. Availability The ability to access iCloud Mail, Calendar, and Contacts using the new authentication flow is rolling out across the new Outlook for Windows, Outlook for Mac, and Outlook for iOS and Android. If you attempt to access iCloud data and are presented with the previous Basic Authentication flow (prompting for an app-specific password), ensure you’ve updated to the latest Outlook app version and restart Outlook. For classic Outlook for Windows users, we recommend trying the new Outlook for Windows, which provides both the new authentication flow and built-in support for iCloud Mail, Calendar, and Contacts without the need for an Outlook add-in.

Hi Outlook Community, I'm posting this after a real incident at work where I accidentally sent a confidential email to the wrong client. After reflecting on what went wrong, I've identified two separate but related Outlook issues that compounded the mistake and I want to raise both here so they reach the right people. Bug: Autocomplete Recipient Changes After You Press Enter This one is subtle but dangerous. When you start typing a name in the To/CC/BCC field, Outlook shows an initial autocomplete suggestion. If you press Enter before the search fully resolves, the dropdown refreshes mid-selection and the contact that actually gets added is *different* from the one that was highlighted when you hit Enter. You don't get any warning. You believe you've selected the right person. You haven't. I've submitted this via the Feedback Portal here: https://feedbackportal.microsoft.com/feedback/idea/9a32197e-5424-f111-9730-0022485314bc Suggested fix: Freeze the highlighted contact reference at the moment Enter/Tab is pressed, independent of any ongoing background search refresh. --- Feature Request: Cross-Domain Recipient Warning (like the missing-attachment check) Outlook already warns you before sending if it detects you may have forgotten an attachment. I'd love to see a similar pre-send check for this scenario: You are about to send an email to recipients across 3 different organisations. Did you mean to do this? In consulting, legal, finance, and any client-facing role, it's very easy to accidentally include someone from Client B on an email meant only for Client A especially when contacts share similar names. A configurable domain-count threshold (default: 2 external domains) with a soft confirmation prompt would catch this class of mistake before it becomes a compliance incident. Key asks: - Configurable threshold (user-level) - Domain whitelist support (e.g., always allow your own org + a known partner) - Covers To, CC, and BCC combined - Non-blocking same UX pattern as the attachment warning I've submitted this as a feature request here: https://feedbackportal.microsoft.com/feedback/idea/9a32197e-5424-f111-9730-0022485314bc --- Has anyone else run into either of these? Would love to know if the autocomplete bug is reproducible for others that would help push it up the priority queue. Thanks for reading. Sudharm PMy Outlook Not Receiving Emails in Office 365
Hi everyone, I’m having an issue where Microsoft Outlook is not receiving any new emails in Office 365. Sending emails works fine, but incoming messages don’t show up in the inbox, even though my internet connection is stable. I’ve already checked spam and restarted Outlook, but the problem is still there. Has anyone experienced this before or knows what might be causing it? Any suggestions would help a lot. Thanks! -Mary
