Office365 - Mail displays jumbled

[gtg93]

OK, so I've been having a problem at one of my schools since September last year, in which if users are logged into Office 365 for a long period of time (so mainly affect admin staff), their emails start displaying jumbled.

 

A bit hard to explain, but basically if they've got three emails in their inbox / a child folder below, One from John, one from Mike and one from Sally - Johns email might show fine, but the subject and one line preview of the email shown in the messages pane for Mike and Sally's email might be mixed up (when they open the email however, the email shows fine.).

 

Obviously not a huge problem, but when you're replying to an earlier message, and see the subject, it's actually the wrong person they're replying to and the wrong subject. Not the end of the world but could cause problems.

 

 

I can't for the life of me figure out the problem. We're running Win 7 Pro and get the issue in both Internet Explorer and Chrome. Some users are filtered some aren't and that makes no difference. It only happens in school so I assume some form of GPO (however GP is from the same template used across most of my sites and only one has this issue).

 

I've reported it to MS Office 365 support team who have remoted in and run all sorts of tests and they can't see an issue so have escalated it to the IE core team who just aren't responding to my emails or the 365 support tech's emails (we've emailed their support desk and the managers of the support team) so I'm at a complete loss.

 

Has any experienced this / got any thoughts?

 

 

[EDIT]

 

I know it's a bit hard to understand so I'll try showing you (I have edited this with paint to remove the names of people and schools and then altered the original image to illustrate the problem we're having):

 

How it should look:

 

How it would look after a period of use:

 

Any help greatly appreciated - sorry for the long question / explanation!

I'm struggling to see the difference between the pictures you have posted?

 

Could it be graphic driver related?

The subjects are switching in the email list - I have no idea why though

As @snagrat has mentioned, it's the subject etc showing on the wrong emails - I should probably have chosen a better example... I'll give the graphics a try when I'm next there. Not 100% that'll be it as they're across different models but I'm happy to try anything anyone can suggest at this moment.

Ah yes, was never great at spot the difference!

Doesn't appear to be a graphics problem after looking today... Finally heard back from MS after emailing the Global Support manage of the support team at Wipro who MS use for their support (how does an IT company not have their own support team?).

 

If anyone has other ideas all suggestions will be welcome.

 

Cheers
