Error while performing the operation

Asked By 980 points N/A Posted on -


I am working on a project, which is  the document  will  received work from team foundation. This project is saved in our Project server. When I want to open the file for some reference I received an error message that I pasted below.

TF80070: Team Foundation encountered an error while performing the operation. It is recommended that you save your work and restart the application

As I understand the error, its very simple and just restart the application. But after I did it, same error is displayed. So I tried re-installing  team foundation client, and restart my computer. But same error persisted. I am now wondering, what this sort of error is all about and what solutions it needs, asking for some help on this error.

Thank you.

Error while performing the operation


Hi there user:

If you receive the error ‘TF80070’, you must save your work and then restart the application. This error occurred because you specified a number which are larger than the ‘Project Server’ allows.

Below are the two (2) things you should be aware of.

 1. Should not specify date later than year 2049.

 2. Number more than 100, 000,000,000,000.  

Project Server appoints these restrictions on Date and Time and Integer fields.

Thanks for asking via
