Contacts on iphone

Yup. My Contacts issue is resolved after restoring from iCloud.com, Advanced Settings.

All Contacts are now stored in iCloud, iCloud is the default account for Contacts, and with Exchange Contacts unchecked, I’ve had no issues. You can export your contacts to iCloud from wherever you hold them. Mine were mainly split between Gmail and iCloud, with 30 or 40 in Outlook.

It has been reported in another thread that upgrading your iOS to all the latest versions (15.6 for iPhone, iPad) resolves this issue. Anyone have success with this? I have just updated everything and was going to give it a try.

Thanks.

Restoring Contacts in Advanced Settings on iCloud.com is what fixed it for me: https://apple.co/3BlCmHL

I coupled that with unchecking contacts for Exchange amd making iCloud the defualt for all contacts.

Neither Apple or Microsoft were any help with this very frustrating issue.

I've got this problem too, for me it's started after loading macOS 12.5 on my Mac. Photo meta data is corrupting other fields but I'm also losing phone numbers, birthdays, anniversaries, etc. All critical data.

I raised a ticket with Apple, no signs of any fix.

Still no fix in sight for me. I'm not using Outlook at all, I've restored my Contact data from iCloud 3 times so far, I've fixed the data that has been corrupted and deleted (Birthdays, Anniversaries, and Photos) each time, but alas within 24 hours the problem occur again.

I believe that there are other programs that try to sync with iCloud, and inadvertently corrupt the data. Are there any other programs on your computer or iOS devices that sync with iCloud? I don’t believe it has to specifically be syncing with iCloud contacts. It could be mail or perhaps(not sure) calendars.

Nothing at all alas. Everything else is okay apart from Contacts data. I do use Thunderbird and eM Client on the Mac, but even if I don't use them (and don't let then sync any data) so I'm just using Mac Contacts and Mail the issue comes back within 24 hours.....

In Settings/Contacts/Accounts (on the iPhone) all I have active is the iCloud account.

I'll go through the list again during the day and look to disable apps which I know aren't trusted, I may actually look to disable all non-Apple apps (if I can) and see if the problem remains. It is worth mentioning though that I'd all the same apps in place that I'm using now and prior to uplifting to the latest versions of iOS and macOS 12.5 I didn't have the problem at all.

Well progress is being mace (hopefully), yesterday morning I revoked App-Specific Passwords for all Apps I'm not currently using which included; Outlook, Mailspring, Spike, Edison Mail, and Airmail 5.

That only left the following which could affect the contacts metadata: Thunderbird & eM Client. During yesterday and this morning I've not been using either of them and had used the native Apple apps instead (i.e. Mail) so the contacts data had not been touched.

So far no Contact's corruption has occurred at all (I am archiving my contacts data daily just in case) so I'm hoping it was one of the apps listed above which had caused the problem....... Anyway my fingers are crossed that the issue is resolved, I'll report back if it reoccurs.

So glad I found this thread. This issue has been vexing me for weeks. I also thought it was Outlook related and after disconnecting all synchronization with Outlook, I thought I have it solved. I even blocked iCloud contacts in Outlook on my MacBook. However, the problem came back, hence me finding this thread.

I have now revoked the app specific password and hopefully that will fix the issue.

Any problems since you did that to your contacts?

The problem is if you block Outlook you will lose all contacts that are linked to your Outlook account. You have to move them to your iCloud account first if you don’t want to lose them, and change the default account to iCloud.

Yup, understood. I had already removed all my Outlook (and Gmail) contacts and aggregated them all into iCloud. The only place I have contacts is in iCloud. I can access them easily enough in Outlook.

That said, I am seriously considering ditching Outlook altogether but I use a couple of add-ins that I really, really like.

Interestingly enough I've just done a massive analysis of email apps for the Mac where eM Client (free for one email account) and Mozilla Thunderbird came top. At the moment I'm loving Thunderbird with a good set of extensions which are giving great functionality. Properly supported too.
