PST file is missing.

The Files where missing in the owners mailbox. But now they're missing in both.

Yes the size is 0.

As an FYI if the mail is missing from the shared side but are in the owners folder: right click on the folder and choose Properties. Then click Clear offline items. This will resync the folder when you are using cached mode.

If the messages are on the shared side but did not sync up to the owner's mailbox, you need to select the messages and copy them to a new folder. I would never 'move' - only copy.

If you right click on the folder, choose Properties then Folder size - is it 0?

It's possible the missing messages are in the purges folder, but it depends on the configuration of your exchange server.

If the shared folder was cached on user1's side, there is a possibility that the messages are in the cache, but AFAIK, ost recovery software can't 'see' it. I have a list of recommended software here -

https://www.slipstick.com/problems/pst-repair/c... - they have trial versions you can use to see if it can find the missing mail.

... und nun?

Thanks, it worked, I could select the profile where to add the e-mail account.
<br />
<br />Now it seems that the e-mail part is up and running again including the synchronization with the mobile phone.
<br />
<br />But I still have trouble with synchronization of contact and calendar entries. I assume caused by the import of a manual created copy of the outlook.pst file. That is the action which initially caused the problems with the missing e-mail account. I lost contacts and calendar entries which still exist on the mobile.
<br />
<br />What is in general your recommendation for backup and restore of outlook data? Currently I copy manually the outlook file once per month and use the Windows backup functionality. But I cannot access the files like "Outlook (2022_01_31 12_35_51 UTC).pst"
<br />
<br /> Is there any tool to synchronize contacts / calendar between android mobile and outlook on the PC?
<br />
<br />Kind regards
<br /> Erwin
