Recently I was trying to validate a Zoho account and kept getting back

Please enter valid mobile number
After it was a valid number. Turns out when you create the zoho account you need to validate the email account before you add Mail. Make sure the email is correct and you have validated

  1. Check the volume has enough free space, if a previous merge (deletion of checkpoint ) has failed this might be why

Navigate to the cluster share and check the .avhdx’s

Windows Explorer - VHDX AVHDX File


Hyper-V Console Method

You can also use the Hyper-V console in Windows 10 to perform the merge operation. The first thing you’ll want to do is open the Hyper-V console. Next, right-click the Hyper-V host and click Edit Disk.

Hyper-V Console - Edit Disk

After clicking Edit Disk, you’ll be presented with a wizard, where you’ll point Hyper-V to the .avhdx file that you want to merge.

IMPORTANT: Select the .avhdx file, and not the .vhdx file, otherwise you won’t see the Merge operation available!

Hyper-V Edit Disk - Locate Virtual Hard Disk

On the next wizard screen, select the Merge action.

Hyper-V Edit Disk - Merge Action

Next, you’ll need to choose the destination for the merge operation. In most cases, you’ll choose the To the parent virtual hard disk option.

Hyper-V Edit Disk - Select Parent

Finally, on the Summary page of the disk editing wizard, just complete the wizard, and it will merge your disks for you. That’s all there is to it!

Hyper-V Edit Disk - Complete Wizard

Shout out to Bennis at Bayswater Electrical for this!

Logpaser is seriously good tool to filter through the mess of IIS logs!

Grab all your ISS log files for the dates you need.

Chuck them in a directory

First command grabs all the .log files into a single csv

logparser.exe -i:iis “select * into c:\temp\merge.log from c:\temp\logs\*” -o:csv

the “–i” option selects the log format  be sure to select the correct format to match your IIS settings. eg, exchange is generally IISW3C.


The second command you use to filter out the details you really need, similar to a sql query!

logparser.exe -i:csv “Select username, date, time, target FROM c:\temp\merge.log TO c:\temp\output.csv WHERE RequestType LIKE ‘%get%’ and username is not null”

Use Excel or Notepad ++ to join the results together

Find the current cert location

sudo vi /etc/nginx/nginx.conf

Look for lines

ssl_certificate /etc/pki/nginx/cert.pem;

Go to Digicert and download .pem with All certs

Use WINSCP to copy this to /etc/pki/nginx/and change the config to look at the new PEM file : 

sudo vi /etc/nginx/nginx.conf

Restart Nginx

sudo service nginx restart

Recently a email came in from a third party which wasn’t blocked by the Impersonation Protection

Administration > Gateway > Policies > Impersonation Protection Definitions  

Default Impersonation Protection for Mimecast 

  • Similar Internal Domain (Similarity Distance 2 ) 
  • Newly Observed Domain ( Checked ) 
  • Internal User Name ( Checked ) 
  • Reply-to Address Mismatch ( Uncheck ) 
  • Targeted Threat Dictionary ( Checked ) 
  • Mimecast Threat Dictionary ( Checked ) 
  • Number of Hits : 2
  • Ignore Signed Messages ( Unchecked ) 

For executives, particularly those who are disclosed on the company website I recommend implementing a hit score of 1 on emails with their name as a display name. 

Exec Impersonation Protection

  • Similar Internal Domain  ( Checked ) 
  • Newly Observed Domain  ( Checked ) 
  • Internal User name  ( Checked ) 
  • Number of Hits: 1 

Administration > Gateway > Policies > Impersonation Protection > New Policy 

Selection Option: Choose the new definition that was just created 
Addresses based on: Both 
Applies from: Header Display Name 
Specifically: INSERT NAME 
Applies To: Internal Addresses 
Save and Exit 

I would advise that display name checks are in place all high profile targets, particularly those disclosed on the company website or other public sources. You also may want to consider alternative spellings. An individual policy is required for each display name.

Recently when a user tried to look at his Online Archive in Webmail the folder was missing. In Outlook 2016 ( NOT Outlook 2013 as this doesn’t support archive very well ) the folders were listed.

The issue is due to the folder count in Online Archives. The folder limit 10,000 and the current folder count was 15,000

Kindly refer to the below article for more information.
