Outlook not responding

Our client runs Hosted Exchange from their ISP. One of the users has a problem. Running MS Office 2013 (I think)

"I’ve been having an issue with my laptop which has been getting worse. Basically my Outlook disconnects/goes into ‘Non Responding’ mode every few minutes so I have to keep re-starting it. This happens from different locations so not the wifi being used."

He can’t risk any major fix like re-installation as he has a vital convention next week.

I suspect his Outlook/Office needs a "repair" such as:

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If a minor Outlook Repair does not work, Office 2013 is not a big risk to reinstall (assuming the computer to be working properly otherwise)

Are there any archive files attached to the profile that are big .

Start Outlook without add-ons. If you do not get the same issue, one of the add-ons is causing it
outlook.exe /safe

Open in new window

What is the exchange version you are running? What kind of activity is performed when outlook freezes? Like accessing PF or address book..

Hello Gerlis,
As expert ‘Christ Harold’ has mentioned, there are various reasons for ‘Outlook Not Responding’ error to occur. But facing errors in MS Outlook account is common and there are various manual solutions available to resolve this. The 3 available manual solutions are suggested here:
1. Open Outlook in safe mode and remove Add-ins.
2. Delete and create new Outlook profile.
3. Repair damaged PST files using Inbox Repair tool.

Refer the below given blog for further step by step information of each method: https://www.linkedin.com/pulse/outlook-keeps-crashing-windows-10-8-7-microsoft-responding-alphy-thms/

But manual solution cannot always resolve the issue perfectly. Importantly it is prone to error and is time consuming process.  It is better to go for direct solution like SysTools Outlook PST Repair tool to recover damaged Outlook PST files without any data loss.

Hope this will resolve this issue.

John:  Outlook Repair has made no difference.

Rajkumar Kamath: There are no Archive files.

All: Remember this is Hosted Exchange. The .pst is irrelevant. I have no access to the pst file.

It's actually Outlook 2010 (a bit older than I thought). I have suggested creating a new profile. (SysTools suggestion) Failing that I will ask him to re-install Outlok/MS Office.

In addition, on the problem computer, make a new, test Windows User Profile (Account). Log into the new Windows Profile, set up Outlook and test in the new Windows Profile.

It transpires that this was caused by an incorrect DNS A Record they also had problems with their Public Folders in Exchange. The mail record (which points to another location) was an old one. I updated it to the correct one and lo and behold it also solved this problem!

Thanks to all who contributed anyway.
