Cant update customer contact info

Let me share some information that can help fix this error in your QuickBooks Desktop (QBDT), lafuturex.

Since you've mentioned that you encounter some errors as you save your data, it's best to use the verify and rebuild data since it removes empty and/or damaged data from the file. Please know that it will also remove or delete transactions that are damaged, which can threaten the overall integrity of your company file.

Here's how: 

Step 1: Verify your data

1. Go to the Window and then click Close all. 
2. Press the File menu, and then choose the  Utilities option. 
3. Hit Verify Data. These are the possible messages that you may see: 

• QuickBooks detected no problems with your data - you don't have to do anything since the data is clean. 
• An error message - search for it on our QuickBooks Desktop support site for how to fix it.
• Your data has lost integrity - Data damage was found in the file. Rebuild your data to fix it.

Step 2: Rebuild your file 

1. On the upper left corner, click the File menu. 
2. Select Utilities, and then choose Rebuild Data. 
3. You'll be prompted with a message that says you'll need to create a backup, click OK. 
4. Enter the name of the file and click Save. 
5. Press OK when you'll see a message that states Rebuild has been completed. 
6. Go to File, and select Utilities. 
7.  Click Verify Data again to check for additional damage. 
8. If there's no error, you can restore your recent backup. However, if there's damage found, it needs to be fixed manually.
