Add unallocated free space to extended partiton

Hey there,
I have a Windows 2012 R2 Server running on VM Ware 6. On the Windows server, i have 4 existing partition in this order: System (350Mg), C: (about 100Gb), D: (about 100Gb), E: (about 100Gb).

All NTFS, the first 3 partitions are primairy and the E drive is extended drive. After adding 30 Gb more space to my virtual machine, I cannot add the extra space to my E drive. Expand is grayed out in Disk Management.
Thanks for tips.

Thanks Seth,
This is what i thought but I couldin't wrap my head around why it would need a third party software if the E drive had the free space to the right of it in disk management. I guess it's really because it is an extended partition.
With Disk Management you can Extend free space between two same partition.

Paragon Partition Manager or other same tools can do it for you.
Have you refreshed your disks to make sure that windows see's the extra space?

Once done did you extend the VOLUME first before trying to extend the partition?

I have refresed the disks. When I right click to extend the volume, extend is greyed out
This is because the space you've added lays out of Extended partition. You need first to allocate it to an extended partition. And as far as I know Windows Disk Management cannot do this.
What you can do however is copying out data from E:, then delete E: and extended partition. Then create new E: partition of the free space and copy the data back.
I could be remembering wrong, but I thought you were able to expand the underlying volume when the last partition was the extended partition you wanted to add space to (as in his case) and the partition would automatically extend to the end to create unallocated space and then you could expand the logical volume to fill that space since it would be contiguous.

However, its been too many years since I used disks with multi-partitions instead of having each disk be it's own separate volume with only the primary partition on it which greatly simplifies the whole process.

  So if I may be confusing scenarios as to when I needed to use 3rd party software, as would certainly be the case if the partition needing expantion was not contiguous with the free space.

So in that scenario, I'd suggest actions disk doctor, or partition magic..  I believe the knoppix boot CD also had some utility which could do this too, however most of these require reboots as they are essentially moving your data.

If this is a VM you should consider cloning the disks to separate volumes for the future as it probably won't be going anywhere
This is really complicated. I hope I will be able to do it alone.
