Hi,I'm Sandy and I look forward to help you today with the best answer possible.
I'm sorry about the issue.
I will work with you until it is fixed.
Please reply at the box given below and type your queries/result at the box given below.
A. Please check the file size again. File itself could be sum up to 21 MB.
B. Some hidden malware/spyware/adware could be causing this issue:
I suggest you to scan your computer using free version of Super anti-spyware software. This will remove all of the malwares, spywares and viruses from the computer.
Note: If you already have installed Anti-virus programs like Norton, McAfee, CA, kaspersky on the computer, still I suggest you to download and install Super anti-spyware as the Anti-virus program does not remove Malwares/adwares/spywares effectively.
You can download the free version using the link given below:
Please run quick scan to complete the scan in 10-15 minutes.
Step C: For testing purpose only:
Make Internet Explorer as default browser as given under:
Launch 'Internet explorer'.
Click 'Internet Options'.
Click 'Program' tab and then click 'Make Default'. Click Apply and then OK.
Step D: Also, reset internet Explorer as given under:
Launch Internet explorer.Click Tools.Click Internet Options.Under the general tab, please delete cookies.After that click the Advanced tab.Under Reset Internet Explorer settings, click Reset.Then click Reset again.When Internet Explorer finishes resetting the settings, click Close in the Reset Internet Explorer Settings dialog box.
Now, please check Mozilla Thunderbird if it works fine or there are still issues with it.
If you have any other query regarding this issue, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
Thank you, Sandy
Could you please tell me if you have followed all of the steps A-D?
Could you please give me an idea of how many emails are stored under Mozilla Thunderbird?
