Outlook App for Android does not sync contacts

Dear Michaelslive ,

I am an independent advisor, and I am trying to help other users in Community with my experience in Microsoft products.

This sometimes happens with the mobile application. In order to resolve this please try to do the following:
1. Check for System updates for your phone
2. Remove the account from Outlook app
3. Delete Outlook app
4. Go to store and check for updates
5. Download and install Outlook app and set up your account using this support article https://support.office.com/en-us/article/set-up...

After you will add the account, go to Settings > select your account > make sure that sync contacts is enabled

Also this Self Help for mobile apps is really useful https://support.office.com/en-us/article/Outloo...

Please share the results.

You may not have noticed but I listed having already done all of these steps.  And more.

Dear Michaelslive ,

I have noticed that you removed the app, readded the account and other. However I did not find that you have enabled the syncing contacts. So do you have it enabled ? If yes go to emails and swipe it from up till down, to sync with the server manually and go to your contacts on the phone and check if you can see them or not.

The biggest question here is why the sync is not complete. You say that calendar syncs but contact do not. Please check one more thing. When you open Outlook app and you select magnifying glass ( at the bottom, between mail and calendar ) can you actually see your contacts there ? Also log here https://outlook.live.com/people/ in browser with the account that you are trying to sync the contacts, and check if you can see the contacts online.

Also please provide the domain of your account, domain comes after @, for example @outlook.com

Stated it multiple times, beginning with the 2nd sentence.  “Each time I ensured Contacts sync is enabled in both Outlook account settings (off by default) and Android Settings\Accounts (on by default).”. While I certainly appreciate people trying to help, please read before you reply.  You are wasting people’s time who will read this in the future not to mention my time now.

I think this is a recent issue. I've had a similar problem myself, but it only started happening in the last month or so.

I have a Moto G5, and my wife a Huawei Y7. We both had Outlook for Android installed, and both had our contacts syncing fine for about a year. A month or so ago, the contacts just stopped syncing for both of us. I've uninstalled and reinstalled Outlook, and reset my account a few times, and sometimes that fixes the issue temporarily. My wife has got around it by adding her Outlook account to the Huawei mail app and removing Outlook, which does seem to have fixed the problem for her. I'm still using Outlook though and the problem remains.

In fact, I've just noticed that the situation has now got worse! Some of my more commonly used contacts have lost their phone numbers altogether from my Outlook account, not just from the phone. Not sure when that happened, some time in the last few days.

Same issue here for the last month or so, contacts for my work account sync fine but not for my personal account.

I have found a solution that works for me

1. Goto your contact (people) on outlook.com website and export all contacts and save the CSV file

2. Delete all contacts

3. Import contacts from the CSV file created in step 1

I then switched Sync back on again in the Android Outlook app and all the contacts have now appeared in the 'Contacts' app too.

Something has gone wrong recently for sure, I am using Samsung S9 with the latest updates, as well as latest Outlook app. 

It syncs one way, Web Outlook to phone, not the other way round for me. Never had this issue before, so I don't think you're alone with similar syncing issues. 

Same issue here on my Huawei Mate 10 Pro. Worked fine for monthes, now I just can't do anything with Outlook cause my contacts are not synced. I am even unable to enable the contact sync, and Microsoft support is failing to help.

Michaelslive...I have had this EXACT same issue.

My main bugbear was that contacts from my office 365 account would not sync with the android contacts, or would intermittently, but only 3 or 24 or so would sync, then it would just stop syncing, then the contacts would just plain disappear from my contacts list.

I found some interesting information and gave it a go and it seems to be working at the moment...

A lot of my contacts on my outlook office 365 account had "categories".  I deleted all of the category information, and voila, all of a sudden, after resetting the account on my phone and clearing the cache for the outlook app and contacts app, the contacts start showing up in the android contacts list.

So, steps for me were...

1. Open Outlook on my PC and go to contacts list

2. Delete all "category" information from my contacts in the list

3. Open android phone settings>apps>...then clear cache for Outlook and Contacts

4. Open outlook app on phone and reset account in the settings screen, then turn on sync contacts in the same menu

5. Open android contacts and ensure that Outlook is ticked in the drop down menu for the list that you want to display
