Missing Outlook 365 Contacts!

I find it strange that you have PSTs but no OSTs while you have an IMAP account.
In Outlook 365, we only have PSTs if we make local backups.

What is your email provider? You should check there, as with IMAP, the data should be on its server.

Yes, I think Gmail is pretty good. But I can't tell you much more, I've never really used it, except on my smartphone.

Hello,

It is indeed curious... When you click on Contacts (at the bottom) to display "My contacts," do you have no list, or do you have empty lists?
And if you search for any contact in the contact search box, checking "All Outlook items," do you find anything?

Have you created a new email address recently?

It’s difficult to understand without seeing your app, obviously.

Are you using POP or IMAP? In IMAP, by default, data is stored in OST files rather than PST since the 2016 version, I believe.

Try to check first if you have multiple PST or OST files, and if so, depending on the dates, try to export.

To locate your PST files: File tab => Account Settings => Account Settings
click on the Data Files tab.

To export: File tab => Open and Export
Click on Import/Export then Export data to a file

Initially, export to a new PST, selecting your mailbox and clicking on the dropdown arrow, select only Contacts.
This way you will have a new PST containing only contacts, you can open it and check if it’s empty or not.
If it gives nothing, it’s concerning... You can do the same thing to an Excel file... but I’m afraid it won’t yield anything more.

Marina is right! If you're using IMAP, you should have the files on the server.

Personally, I changed addresses two years ago after having used the same address since the dawn of time!! :)

In fact, I emailed all my contacts to let them know. Obviously, I kept and still keep the old address in Outlook and I check it regularly. When I still receive some emails from certain senders who weren't aware (not everyone is in our contacts), I set up an Outlook rule to change the destination folder. Little by little, we're managing even though it takes some time. Now I mostly get spam on the old address. But I will never delete it... even though it doesn't serve much purpose anymore, I don't want anyone to steal my address which is still mine!!! :)
