Shared Calendars No Longer Visible
For years, I've shared Outlook calendars between my Outlook accounts and with my husband's, without any issues. However, since mid-June the shared calendars have disappeared for no apparent reason. The sharing permissions are still in place, but the calendars are no longer visible or available to add on Android, in the Outlook desktop app, or on Outlook on the web. I've spent hours Googling and tried all the usual troubleshooting steps, but nothing has worked! As a workaround, I now have to invite all @outlook.com accounts to calendar events just so everyone can see them and avoid double bookings. Has anyone come across this before and found a fix that isn't one of the standard "how-to" suggestions? Note: these are personal paid Microsoft accounts.
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!

Outlook Android “Sync Contacts” disabled for Microsoft 365 Business Standard tenant
I am the Microsoft 365 tenant administrator. Outlook and Authenticator work correctly on Android. The “Sync Contacts” toggle inside Outlook is disabled/greyed out. 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 For Android Search Not Working with IMAP Folders
I have been trying to get Microsoft to fix Search not working for IMAP email account folders for a number of years. Even though Microsoft support have confirmed the BUG multiple times no fix has ever been provided. I am again in a discussion with Outlook For Android support via the support Live Chat option within Outlook but the support engineer basically says I am the only person to have ever reported this bug to Microsoft... Now obviously a quick Google shows may users complaining about the same bug from around 2019 onwards... but for some reason Outlook support do not seem to be able to use Google... For those that may not know of the issue, the Search function will only work with Outlook email accounts or Gmail whne an email has been moved from the Inbox to another folder. If you use a different IMAP email provider and use Folders to move email into from the 'Inbox', the Search function will not find those emails - ever. (The Search function seems to work for the inbox only with IMAP accounts.) So I have a request! Please, any Outlook for Android users that have this issue PLEASE report the BUG to Outlook for Android Support via the 'Settings/Help & Feedback/Contact Outlook mobile support' option. The more users that report this ongoing issue the better, and we may get Microsoft to take it seriously, rather than fobbing users off with a 'no-one else has the issue' response!
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.

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? TIA
