For Online Computer Support, Ask a Computer Technician
Hello & Welcome to JustAnswer. My name isXXXXX I will do my best to assist you.
If the mail server goes down (the exchange server) it will stay on the internet and will attempt to resend when the server comes back to life.
To make this better, i need to ask you a few question so i can understand your model more clearly.
Can you tell me why did you chose to host exchange at your office and why not online?
Please leave me a short message when you are back so we can continue.
Hi we used to get email via a pop3 connector but this often seemed to be have problems, so when we set up the server with SBS2011, using exchange on our local server was recommended as the best solution.
We are not bound to this however and open to considering other ways to configure email.
That brings management and extra cost in the world of cloud technology.
Eventually, an IT Support Company.
If it is just for emails, then you could get a hosted solution (hosted at a secure data center with backup and no downtime)
To make the existing solution better, there are a number of things that can be done.
#1 The first one is to get a UPS to work with the server.#2 Setup backups for the server#3 Setup back up MX records (so that if the mail server is down) then the mail will be sent to another server (which can be an online hosted one)#4 Turn Windows Updates Off#5 Setup Antivirus for server
Normally, people do not keep mx records for more then one server because SMTP for most of the mails (depending on the configurations) adds a flag to the message (to retry) if the recipients mail server is down.
1. we have a UPS set up with active monitoring and automatic shutdown
2. we have regular backups scheduled
3. this is probably the bit we need to sort out
4. why turn off windows updates ? - this is currently done automatically and managed via SBS2011
5. currently use ESET nod32 which seems to work well
3. This is not always needed, it is just one way - Use it only if you are having issues because if it setup, then users may experience problems and this will require extensive troubleshooting to configure it to fit requirements.4. Windows Updates should be turned off on production servers because (if update, updates something that results in incompatibility) it will bring up unnecessary issues. It should be set to download manually, so you can check it every week or so and update it manually. By doing this, you will be aware of it and if a problem happens, you will be able to resolve it easily.
I have seen issues where certain things becomes non functioning after an update and then people spend hours resolving issues that comes after update.
MX Backup - Here's How
3. Once it's properly setup, it's good
ok that makes sense we did have an issue with an outlook update, which caused a problem recently and it did take a little while to sort out.
I will have a look at setting up the MX backup, I had a quick scan through and should be ok to do, but will need to do this later.
I will finish now and get back to you if I have a problem
thanks fro the helpful reply
Take a look at this site: http://www.mxsave.com
Also, let me know when you plan to setup back up mx so i can find you reliable solutions and assist if any problems occur.
This should be done over the weekend.
