SharePoint OWACalendarPart : “An error occurred while attempting to add the item to the page.”

I’m trying to use Outlook Web Access Web part in SharePoint Server 2013. I have added the OWACalendarPart web part to Web part Gallery using following Methods.

1) Go to Web part Gallery.  2) On Web part Gallery page, Click Files-> New Document -> New in the ribbon.  3) On New web part page, look for Microsoft.SharePoint.Portal.WebControls.OWACalendarPart,     Select the web part and click on populate gallery. 

Now, I navigate to the SharePoint page where i want to add web part, clicked on Add web part. UnderMiscellaneous Category, I see OWACalendarPart.

When I click add, the page always saying “An error occurred while attempting to add the item to the page.”

I tried Several Times But Nothing helped.How to add this OWACalendarPart to the page?

UPDATE :

This is the error I get from Log.

An error occurred while attempting to add the gallery item [Miscellaneous]     OWACalendarPart to the page.

“An error occurred when navigating to:” error occurs randomly approximately every third time certain users try to access particular documents

At my company, certain users, when trying to access documents via links outside of our SharePoint environment, are getting an error saying “An error occurred when navigating to:…”. This error is happening for the users irregularly. If they get the error and then click the link again, the error goes away and they get access to the document. I am not an expert in SharePoint, but would this imply that one of our content servers in our load balance is not working properly while the others ARE working? Can anyone tell me how I could go about solving this issue? Any thoughts or comments would be appreciated!

Unknown error has occurred. The form template has been published to the server but it can only be opened in InfoPath Filler

I have gotten this error before and to fix it, I created a new external list and new form. But when going back in and editing the new form, it doesn’t even publish and keeps giving me this error. I tried creating a new external list and form again, but it still keeps giving me the same error. I also tried the recommended sharepoint solution to add the Desktop feature, but my computer already has it installed. I am not locked out of my account either.

“A problem occurred while connecting to the server” when opening documents from SP2010 in Office 2010 application

We have a strange issue that seems to appear after the weekend. It appears that when opening documents from our SharePoint 2010 environment (Excel, Word, etc) the end user no longer is able to ‘check out’ or ‘check in’ the document from the client application. Instead, they receive a notice at the top of the application:

Server Read-Only This workbook was opened from a server is read-only mode.

..and the option is there to “Edit Workbook”.

When clicking this option, they receive an error:

“A problem occurred while connecting to the server. If the problem continues, contact your administrator.”

Now, I have diagnosed the following things:

  • Checking out the document first from the browser and then editing it allows the client to continue working, but they must checkin/checkout from the browser – there is no option in the client application anymore

  • Ensured that Windows 2008 WEBDAV is disabled on the Web Front Ends and the Application server. This has always been disabled as far as I know. An article I read mentioned that the Windows 2008 WEBDAV will interfere with SP2010 ‘s WEBDAV and it should remain disabled.

  • Turned on Fiddler and didn’t notice any errors whatsoever. Just a call to “/_vit_bin/cellstorage.svc/CellStorageServer” when the “Edit Workbook” button is clicked from within the client application.

  • Verified I have Version 14 of the “OpenDocuments” class IE add-on, which corresponds to our Office 2010 version.

I am currently at a loss as to what may be causing this all of a sudden. Something obviously changed on the weekend, but I cannot seem to determine WHAT exactly. Thoughts?

An error occurred while loading the model for the item or data source ‘EntityDataSource’

I use SQL Server 2012 SP1 U8 and SharePoint 2013.

  • I configure Excel Service and Performance Point Service and PowerPivot Service.

  • I create an Excel File`that fetch data from Data Warehouse in PowerPivot report.

  • I load this file in Documents in my SharePoint web site.

  • When I click on my Excel file in SharePoint, I get this Error:

enter image description here

I see this Power View Fails to Connect link but the answer does not work for me.

And this Link Power View Error: An error occurred while loading the model

Note: I can see all Excel report that does not have the PowerPivot component.

An error occurred starting StarCraft II. Please try again. (18.04)

In January 2019 I switched to Ubuntu 18.04. To my great relief I was able to easily install StarCraft II through Wine. That was the end of the story until now, when I got a new computer, but this time I’m having a lot more trouble. Thanks to this very site, I was able to install Battle.net (though I was having quite a bit of trouble with it for other reasons), but then, after installing StarCraft II, I couldn’t get it to start. When I try to start StarCraft II, I get an error message saying ERROR: Game Initialization Failed: I followed by another error message saying StarCraft II: An error occurred starting StarCraft II. Please try again. (Error 2:1), and then nothing.

If I tell Battle.net to try running the 32-bit version, the error messages don’t appear, but it still doesn’t actually start (and the latter message will appear if I kill SC2.exe). I can’t find much useful information online about either of these messages, so I’m asking about it here instead.

An unexpected error has occurred. Web Parts Maintenance Page: If you have permission, you can sue this page to temporarily close Web Parts

I have updated SP2013 farm to SP2016 in a new environment. Everything went well except some customised web parts. When I click on ex “Create customer” which is a customised webpart I get the error message:

An unexpected error has occurred. Web Parts Maintenance Page: If you have permission, you can sue this page to temporarily close Web Parts or remove personal settings. I have already deleted and readded the webparts, edited the web.config with different solutions which I found on the Internet but I just got more problems. I have even deleted and reinstalled the PerformancePoint service application. When I try to add a standard SP webpart, it works fine but not the customised webpart.

Have you please any idea about this issue and how to solve it?
