Safe senders and domains in the Outlook Web App in Office 365

Safe senders and domains in the Outlook Web App in Office 365

In this post we will show you how to manage your safe senders and domains in the Outlook Web App

Office 365 has a very good email security and spam filtering system but sometimes it can be frustrating when you keep on getting the same old messages, from the old same senders, always going into your Junk Email folder.  Simply moving these emails back to your inbox does not have any effect and the next email you get from them goes back into the Junk Email folder.

If you are experiencing this issue and you have legitimate emails that are ending up in your Junk Email, you can easily add the email address to the safe senders and domains list which effectively whitelists them and stops the problem.

If you’re familiar with Hotmail or mail, it is a very similar process.

Here is what you need to do in the Outlook Web App in Office 365
  • Log into your Office 365 email account by going to
  • If Outlook doesn’t open by default, click on the Outlook app icon.

    manage your Safe Senders and Domains in the Outlook Web App in Office 365

  • At the top right of the screen, click on the settings wheel, and select View all Outlook settings.
  • Next click on the Junk Email section and then click on the Add button by the Safe senders and domains section.
  • Enter the email address or domain that you want to approve and click the save button – it is as easy as that!

Excel Blank Window Error

Excel Blank Window Error

Yesterday one of our clients encountered a very annoying error in Microsoft Excel 2016, a blank window error. Admittedly there was no actual error message, but when you can’t see any content it’s quite an issue. While we were investigating the issue we found that any Excel file we opened it would be blank or “grey”. However, we were able to open them if we went to File > Open, which was interesting.

We tried to repair, re-install and numerous other fixes but the one that ended up working was ticking a box then unticking it, how peculiar!

Steps to resolve Excel blank window error

  1. Open Microsoft Excel
  2. Go to File
  3. Options
  4. Advanced
  5. Under General tick the Ignore other applications that use Dynamic Data Exchange (DDE)
  6. Close and open Excel
  7. Then follow the same steps and untick the box

Microsoft ends Windows 7 and Server 2008 R2 support

Windows 7 and Server R2The day has arrived and good old Windows 7 and Server 2008 R2 are finally retiring and support for these operating systems is going to be discontinued.  It has been a good run and we have had many years of dependable computing and decent server operating systems.  Windows 7 was probably one of my favourite Windows builds but with age and new ways in which technology is doing things it just could not keep up.

What will happen with Windows 7 and Server 2008 R2
  • No more Bug fixes
  • No more security Updates
  • No more Malware protection
  • Compatibility issues with applications

Seriously though I know a lot of our followers are still using Windows 7, it is not just going to stop working today but using these operating systems will slowly become more and more risky as there will be no more updates or patches plus hackers are surely going to target it and find as many exploits as possible.  Remember a few years ago when Ransomware was rife? It came out of nowhere and hit a lot of systems that were not completely up to date, well I can see similar problems in the future for Windows 7 and 2008 R2.

We can help you upgrade from Windows 7 and Server 2008 R2

I know it is different and we do not like change, but Windows 10 has evolved and has got better on every new build and update furthermore TC-IT Services can help make the transition over to this new operating as seamless as possible for you.
If you wanted to do the process yourself you can start by going to the Windows 10 download page;

If you are still running Server 2008 R2 or SBS 2011, which runs on Server 2008 R2, you need to act sooner rather than later as having your server attacked could have much more serious consequences.

At TC-IT Services we are cloud service providers so have many options to migrate your server to the cloud.  If you are still using Exchange 2010 or higher, we can migrate all your email and other Outlook data seamlessly to Office 365 as well.
OR if you still want the ability to have your own server and control where you data is, upgrading your domain or stand-alone network to Windows Server 2019 is pretty straight forward. We have performed many of these migrations for our customers to date so we can help with this.  Once complete we can de-commission your old server or domain controllers properly making the transition seamless.

There are so many advantages of Windows 10, migrating your servers to the cloud or moving to a current server operating system. If you need any more information or just want to chat about it all please don’t hesitiate to speak to one of our experts on 01273 987926 or contact us here.
