Common Problems behind Outlook 2007 Freezing – How to Fix Them?

Microsoft Outlook is undoubtedly one of the most widely used email clients for both individuals and professionals. Being a very popular email application, it goes without saying that Outlook often makes users distressed when mailbox freezes or stops responding suddenly. There are several reasons why Outlook freezes or stops working. These reasons, in turn, cause a stressful situation for the users. Here are some of the common reasons behind erratic behavior of MS outlook and solutions to fix them –

Outdated Windows and MS Office

MS Outlook may also hang or freeze if user doesn’t install latest Windows updates or even MS Office. So, you have to change Windows Update settings by setting them to automatic to resolve this issue. It will automatically replace all the outdated files and fix the vulnerability on time.

Outlook is Currently Used on Other Process

Sometimes, Outlook doesn’t respond because it is being engaged in another process and the same information is being displayed on status bar. In that case, you have to wait for the task to complete in other process and mailbox is free.

Oversized User Mailbox

Oversized mailbox is another major cause why Outlook hangs or freezes constantly. Along with the number of resources to access various features, the size of mailbox is also subject to increase over time. In that case, mailbox freezes when it comes to access several features at the same time.

Unsupportable Add-ins

Sometimes, users install or download the add-ins which doesn’t work with MS Outlook smoothly. If the freezing issue takes place after installation of add-ins, it is better to use mailbox that doesn’t contain add-in. If this problem is fixed after you disable the add-in, it is better to use Outlook next time without add-ins.

Outdated Antivirus

A conflicting Antivirus program may also cause Outlook application to freeze all the time. So, it is vital to ensure that antivirus is up-to-date and can support the mailbox to ensure proper performance.

Corrupt PST File

It is, by far, the most common reason why Outlook crashes a lot. The unexpected and weird behavior of corrupt PST file can cause Outlook to freeze or hang. Microsoft understands that this issue may occur any time. So, it offers scanpst.exe, an Inbox Repair tool to deal with it. All you have to run scanpst.exe to scan all the PST files stored in the system.

To fix corrupted PST file, this tool needs multiple passes in most cases. So, you have to run this program again and again until it shows no error.

Sometimes, corruption issue is so stubborn that even this tool cannot fix it. In fact, it shows that it has not found any error. But you would still encounter problem after using it. In that case, you need to create a new file and transfer all the old PST items into new PST file. Close the old PST file after doing that and use the new PST file. You can also use it to scan and repair corrupt Offline Storage (OST) file.

 

Common and Worst Reasons of Hard Drive Failure

Whenever hard drive failure takes place, we mostly get panic and wondering how to fix it? Believe it or not – it is not easy to fix hard drive failure. As a result, lost data is very hard to get back. Hence, we need to look for professional services for hard drive repair.  When recovering data yourself works in some cases (including recovery of some deleted files), if you don’t know what to do, you may do more harm than good to your hard drive and ruin the likelihood of successful recovery. There are different reasons behind the failure of hard drives and each of them has their own contributing factors. Here are some of the most common signs that can cause hard drive failure –

Physical Damage

Shock, heat, and water all are the biggest enemies to your external and internal hard drives. Both water and heat may lead to serious physical damage to the circuits in your hard drive that are not capable to withstand any element. These drives are not shock resistant. So, even a small drop or any physical impact can cause huge damage to the mechanical parts of the hard drive. Most often, head crash is caused due to hard drive shock. It takes place when its read/write head comes into contact with magnetic platter, scratch the surface, and cause data loss which is sometimes irrecoverable.

Warning Signs

  • Improper ventilation causes overheating and hard drive failure eventually. Be sure that the fan in your computer (usually on the rear or bottom of the machine) is not blocked for proper ventilation.
  • Your PC also shouldn’t be too hot to touch.
  • Shock and water damage are also difficult to avoid. It happens all of a sudden without warning. Take proper care of your PC to avoid these risks.

 

Logical Failure

It occurs when hard drive’s software or file structure is damaged, instead of actual hardware. It is a non-physical damage. There are several factors responsible for logical failure, such as human error, virus attack, corrupted files etc. The failure is, sometimes, so huge that systems won’t boot. In several cases, hard disk recovery service comes to the rescue to recover all data as drive’s hardware is safe.

Warning Signs

When you come across these signs, it is best to backup your data, if you don’t have one. If there is no other way to access data, look for a hard drive recovery service.

  • Disk errors
  • Disappearing data
  • Sluggish performance of your system
  • Annoying ‘blue screen’
  • Computer crashes

 

Mechanical Failure

A computer has only a few mechanical parts and your hard drive is one of them. Basically, most components are electrical. Hence, it may inevitably fail at any time. When any component like read/write head goes faulty due to normal wear and tear, such kind of failure takes place.

Warning Signs

Watch out for strange noises like clicking, grinding, or screeching. These are the common signs of mechanical failure. Like logical drive failure, frequent freezing and computer crashes may often occur.

 

Conclusion

With little planning and some common sense, you can easily deal with most of the reasons of hard drive failure. In addition, you can also help reduce the risk of disastrous situations.

If all precautions did not work and your data have been corrupt, then you need a application to recover data back in working condition. Use free trial version of this Windows Data Recovery software, this tool will recover your 1 GB data at free of cost. Go through free version to see results.
