Hello Everyone,

I need help if anyone can help. We exported outlook contacts to a csv file from one user and imported that to another user outlook but after importing the contact outlook and mapping it properly the email addresses disappear after some time in the 2nd user outlook. it stays there for some hours and then disappear from the outlook. I did that multiple times but the same issue happening again and again.

Thank you!

    Is the contact already in the folder but the import adds an address?

    Is the user syncing with a smart phone or another device?

    Hi @Tariq Mehmood ,

    Yes they are syncing with an iPhone.

    In case it's a sync issue involving the mobile device, you can try temporarily removing the account from iPhone and see if the email addresses can stay.

    Besides, you can also try exporting and importing the contacts via PST and check if there would be any difference:
