Though, the private account is not syncing on my samsung S26 phone.

Even after deleting account and or outlook.

How d o i solve this

Answer 1

If your work account is syncing but your personal Microsoft 365 account isn't, check that syncing is enabled for the account in the Outlook app. If it still doesn't sync after you remove and re-add your account, sign in to that account though Outlook on the web to make sure it's working.

Hi Jurgen De Daele,

Please note that our Microsoft Q&A forum is a public platform, and we will modify your response/ question to hide your personal information in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data.

Since the issue only affects your personal Microsoft account and you've already tried removing the account and reinstalling Outlook, the problem is likely related to account authentication, sync settings, or Android background restrictions. Please try the following:

1. Open Outlook > Settings and select your personal account.
2. Verify that Mail, Calendar, and Contacts sync are enabled.
3. On your Samsung S26, go to Settings > Apps > Outlook > Battery and set Outlook to Unrestricted. The menu may differ depending on your device or software version.
4. Remove the personal account from Outlook.
5. Clear Outlook's app data and cache.
6. Restart your device.
7. Reinstall Outlook and add the personal account again.

It would also be helpful to check whether the personal account syncs correctly in a web browser. This can help determine whether the issue is specific to the mobile app or the account itself.

To help narrow down the cause, could you please let us know:

• Does the issue affect only email, or also calendar and contacts?
• Do you see any error message when Outlook attempts to sync?
• Does a manual refresh work, or does it fail as well?

I look forward to your update. Let us know the results and we'll be happy to assist further.
