However, a most basic question would also be 'Can Windows Phone 10 read Bitlocker encrypted micro SD cards?' And my answer, from personal experience, is NO..
.. Can Microsoft listen to users and take care of this? This is really crucial, in my view. Thanks.
We are MSFT partners and developers and several of our team are former MSFT Blue Badges, so please take this with the caveat that we are both a) no strangers to Windows in small packages (CE, Mobile, Phone, then Mobile again), and b) we are not here to bash MSFT - we are quite pro-MSFT around here.
This is a feature (one of many, sad-to-say) that was AVAILABLE in Microsoft Windows Mobile 6.x - the OS based on Windows CE that came before Windows Phone and Windows 10 for Mobile. See this blog entry for more info.
It worked very well, very quickly and kept the entire device (phone or palm-able) encrypted.
Given that this is the case, the way we see it, this is just another in a long line of reasons why Windows 10 for Mobile just isn't really cut-out to be a business-class OS (at least, not in the way that CE or the original WinMo was, for small devices).
It is also one of several reasons why we don't develop our hand-held platform products on Windows 10 for Mobile. Another reason: the fact that the W10Mo platform might as well be an Apple iOS platform, in the way MSFT keeps a very tight rein over the ability to build device-drivers for W10Mo. Our devices require kernel-level drivers to perform well, and MSFT won't give us 'approval' to build them, so we're stuck on Android which works but which most of us do not really like.
I second that request. If it's truly MSFT's intent to keep making Mobile platforms (vis-à-vis Surface devices, for example), they need to get off the pot. Not to do so would be to cede the ground to Google.
I was using Active Sync on my Android Galaxy S2 and as a result it enforced encryption of the phone and SD card.Phone did a factory resync and now data on SD card is still encrypted.Is there a way to recover the data off the SD card?Is the key required to decrypt the SD card stored on the card?Is there any external software I can use to recover the SD card contents?

You should not be able to recover the contents of the SD card if you've done a factory reset. It's designed that way and is a good thing as it protects data being read if your phone has been lost or stolen. Unfortunately for you in your situation, unless you have backups your data is lost.

There seems to be somedebate over whether or not the SD card can be encrypted; Android did not support external media encryption when it was introduced, and the current state of that feature seems to vary significantly between the various versions of Android.
The most authoritative source I can seem to find is from a forum post (the authormay be a Google Software Engineer:
Encrypt Sd Card Storage Box
2012/1/10 Marc Blank : The answer here is somewhat nuanced. ActiveSync can require that the device and/or sd card be encrypted, and we enforce those policies in ICS; however, ICS does not have the ability to encrypt removable storage (i.e. SD cards). So here's what happens:
Total war warhammer demigryph knights vs reiksguard. 1) In all current versions of ICS (up to 4.0.3), we accept the 'encrypt device' requirement and reject the 'encrypt sd card' in all cases (reject = we don't allow the account to be created/synced on device) 2) In the next update to ICS, we will also accept 'encrypt sd card' if and only if the device is encrypted and it has no removable volumes (this is true of the Nexus S and Galaxy Nexus); on these devices, all internal storage is encrypted when device encryption is enabled.
Having said that, the Email/Exchange application never stores emails other than in internal storage; however, user can still choose to save attachment files to 'sd card' (which may or may not be external) unless, of course, the ActiveSync policies are set up to disallow loading of attachments.
Does this make sense? Sorry if it's complicated, but .. that's how it is!
Marc
Having said that, in general I agree with the comment by Polynomial - it will probably be impossible to recover the contents of the SD card.

There is a good chance the encryption key is stored on the SD Card, but itself encrypted with your unlock password. Try encrypting your phone with the same unlock password as before, then inserting the SD Card.

I have files that I used to copy from my SD card to my PC using the USB Mass Storage option under the 'USB connection' pop-up. I checked the flag under Settings->Location & Security->Data encryption->Storage encryption and now I can't read new files of these types (e.g., .jpg and .txt files). I tried unchecking the box -- a message appeared saying that future files will be decrypted, but existing files will remain encrypted.
How do I access the files that are currently encrypted and/or decrypt them? Water is to be moved from one large reservoir.

I sent this question into Verizon Wireless as well. Here is their reply:
Encrypt Sd Card Storage Case
Thank you for contacting Verizon Wireless through our website..I understand that you've been having an issue trying to decrypt files on your handset. At this time Motorola hasn't provided an update for your phone to be able to do this. Without that, we're unable to assist you because this is a phone issue and not a network issue.
Encrypt Sd Card Storage Location
So it looks like Ryan was correct in his comment that this is an issue with a Motorola OS add-on, not vanilla Android.
Since originally asking my question, I experimented some more with my phone. My phone has 2 check-boxes for setting encryption: one to encrypt the SD card (that I mentioned in my original question) and one to encrypt the main phone memory. When I unchecked both boxes, my phone decrypted all files, both on the phone and on the SD card. So, that is my solution for now.
Thank you Ryan for your comments -- they helped lead me to this answer.

I'm using Samsung Galaxy Note, ICS 4.0.3. There's a Decrypt option.Go to Settings → Security → Encryption, there's a 'Decrypt Device' and 'Decrypt SD Card' option.
After you select 'Decrypt SD Card', just uncheck all the boxes on the next screen (see screenshot below).

Summary: With a Motorola Droid series phone using encryption, you have to click to use the phone as a 'Media Device', not as Mass Storage, in order to decrypt files for transfer or viewing on a USB connected PC.
OP has stated he is using a Droid Bionic with encryption enabled.
To view or transfer the encrypted files to his PC -- but in a decrypted state -- while the phone is plugged into his PC by USB connection, he should:
Source: I have a Droid phone with encryption enabled, and did this procedure to transfer files in a decrypted state.

Two month ago, I encrypted my Micro SD card in my Android device (Samsung Galaxy S5) for security purposes, and yesterday I forgot to decrypt it whilst removing the card I and factory resetting the device. Is there any way to decrypt it by using the same device, if I set all the settings the same?

Hope you didn't format your sd card yet.I did the same thing with my S7 edge but managed to fix the problem.Headphone jack stopped working so Samsung support recommended a factory reset to rule out software problem.After backing up with the smart switch program and factory reset were performed, the files on the sd card couldn't be read properly.The file names/folder structure were all there but when you tried to view an image or read text nothing was readable (the files were the same size as before the reset).Here's what I did:
After that I was able to view all the files I had on the sd card!
