Ever since we upgraded our system to 10.3.1, we have been experiencing issues with how Office documents are opening using Microsoft Office Online.
Specifically, when a user tries to open a document for editing, the user is prompted to use the Microsoft Office Add-In, whereas if the user tries to simply view a document, the document opens in Microsoft Office Online, however when the user chooses to Edit in Browser, this button is greyed out and cannot be used. Further, if I try clicking within the open document and try to make changes, I get a prompt saying the document was opened as read-only and cannot be changed, and the Enable Editing button is also greyed out.
The very weird thing is that some documents can be edited (i.e. the Edit in Browser button is active), and it seems to be available to any documents that I have created after the upgrade.
Some of the things I have looked at to this point:
1) The permissions to a document that could be edited versus one that couldn't were identical (I have full Admin permissions on both).
2) Looking at user permissions, regardless of who is logged on to the specific computer:
a. If the user has "Open in Browser" set in their Display Options within Laserfiche, it will try to open the document within Office Online each time, however with the Edit in Browser button greyed out.
b. If the user has "Download electric file" set here, it will try to open the document using the Office Add-In. However, even if the Add-In is configured and working properly under one user profile on that machine, the installation still needs to be done under all user profiles.
3) Remembering this issue was not happening in 10.3, I tried both downgrading from 10.3.1 to 10.3, as well as reverting to the snapshot I took prior to upgrading to 10.3.1, but neither of these fixed the problem, which leads me to think the problem *may* have been there previously.
4) I tried uninstalling the Add-In completely (thinking it might default to Office Online), but this wasn't the case.
5) I tried disabling the Chrome Laserfiche extension, but if the registry setting was set to "Download electronic file", I would get prompted to download the Laserfiche Add-In (although this appears to be an expected behavior).
So I have two questions here:
1) Is it default behavior to have an Office file open (using the Edit button) using the Office Add-In? My thought is that if Office Online has been turned on and configured, an Office file should open for editing this way each and every time, and a user should never be prompted to install or use the Add-In.
2) Is there a possible behavior within Office Online that would set all documents to open normally, and not read-only? Seeing as this issue happens with almost all documents, I get the feeling there might be a configuration setting in Office Online (whether application or registry) that might change this behavior.
If anyone might have thoughts on things to try here, I would love to switch to Microsoft Office Online completely and move away from the Add-In, as the Edit in Browser feature works very well once it's configured properly!
