Excel: message "A newer version of this file is available on the server" when editing with Office

[ABarth]

Hello everyone,

Since upgrading from ACS 23.1 Community Edition to ACS 23.4.1, we have problem while editing Excel in Office :

1. From Alfresco Share, open the file with "Edit with Microsoft Office"
2. File open in read-only (expected behavior, OK) -> click on "Enable editing"
3. A message shows with "A newer version of this file is available on the server"
4. After clicking yes, the file finally open in edition

This new behavior is causing many issues with saving document and lots of confusion for the users. Notably problems with:

• Password protected files (you need to enter the password twice!)
• Files with macros
• Files with external data sources (you need to do "Save as..." and then import to Alfresco..)

Did anyone have the same issues or successfully configured Excel to open files from Alfresco directly in edition mode ?

We also tried downgrading the AOS module from 3.2.0 to 2.0.0 -> same behavior.

Best regards,

Adrien

Versions :
