[Exchange Web Services] Synchronizing folder ‘***/Contacts’ failed due to the following error: The attachment could not be opened.

Is there a solution set for this problem? My contact list has been reduced to 69 files. Is there a way to fix this?

My contact list has been reduced to 69 files.

If your contacts are all showing & opening ok online via your webmail, then could be your local account cache is corrupted and needs clearing.

So first make a backup via “Menu / Backup”. You can see when that’s completed in Show Operations via the dropdown in the right of Refresh.

Once backed up, go to the eM Client Contacts section and “right click on the word Contacts” directly under your Exchange account and click “Properties” at the bottom. Then click the “Repair Tab” & Repair.

Once the local cache is cleared, your contacts might take a little time till they all come back from the server depending on how many you have. Then see if that fixes the problem.

If that still doesn’t fix it you might then need to go to “Menu / Accounts” and remove and re-add the account via the automatic account wizard.

Apart from that if you originally installed eM Client directly from the website, check you are running the latest version for whatever you have installed incase you have an outdated or older version.You can check that via the release history page.

Thank you. The problem was deeper than that. During the sync process, if a contact file had notes, attachments or documents, the sync with Outlook would fail. Also, any incoming email that matched that contact failed to import into emclient. I spent two hours digging into this and found that any contact in Outlook Exchange with notes, attachments, or images caused the sync to fail, and mail wouldn’t be added to emclient. Once I resolved the contact-notes issue, the contact list updated correctly and email from over two weeks ago appeared. The early issues I posted around three dots beside a folder were directly related to this issue.

I have now solved the problem.
