I have been blessed with the task of learning and troubleshooting evault enterprise server 12. So far things are going well but I have a few issues that I have been asked for assistance.

In our environment we have several users at any given point whose local vault cache we have to reset, because the Outlook client stops connecting to the server. In some of those cases building a new outlook profile works also.

I have searched the event viewer logs and cannot find anything really consistent with what is occurring (mind you I am not there when this occurs). All I hear is the last time the Outlook client (version varies 2010, 2013 and 2016) was such in such date and now it's not syncing. Consequentially, we copy all the items out of the "to archive" folder up to the exchange mailbox and reset the vault cache.

One last thing, the Exchange portion works in cached mode or in online mode. Any leads on how to attack this issue

Can some one tell me the procedure of cutting over from Message Labs to Mimecast please
so here is an odd situation today, we use O365 and ceo got 2 emails but the subject line somehow swapped but the email content remains the same

as an example

Email 1 > msn news > Subject is > latest news headline

Email 2 > cnn news > subject is > electrical insight

but Email 2 has Latest news headline and Email 1 has electrical insight, he is asking for an explanation and this one puzzles me

any ideas?

We've got a problem with receiving a calendar invitation in Outlook on one of our client's computer. The invitations come looking like diagnostic or source with headers. It doesn't matter if it's an invitation from O365 calendar or Google calendar. This is the IMAP account from and he uses Outlook 2019. Can anyone tell me what could cause the problem?
Below is the example email.
Kind regards,

I have just registered a new business with Google For Business (GFB) to avail of a company Google mail account using my new domain name.

I already use GFB for two other separate business emails, and I've never has a problem with either of this email accounts.

I am not facing 3 problems with my new account:

01 - on iOS Mail i don't see an option to select Push under 'Fetch New Data'... I just have Fetch or Manual... where as my other domain accounts have 'Push, Fetch or Manual'

02 - on iOS Mail, when i swipe left I don't get a delete option... where on my other domain accounts it 'deletes' the email

03 - on Mac Mail (desktop), I get strange behaviour with my mailboxes under the 'On My Mac' section. If you look at the screenshots you will see that the new mailbox has both a number on it and it expands with a drop down, however none of the other mailboxes in 'On My Mac' expand like this. This is really annoying as the number keeps grabbing my eye. Does anyone know how to remove this... and / or why is it showing number in All Mail and Important in the drop down.

Thanks in advance for your help.

In Outlook, there is this tracking options to send a read receipt. When this read receipt is being sent out.. will it be shown shown as sent item in Outlook? We can't seem to find this sent  read receipt captured anywhere in Outlook or webmail. Will the email service provider have a log of this and how is this read receipt being sent out to the recipient?

Good Day

I'm currently busy doing servers upgrade for one of my customers; a 5 site / campus college.  Exchange site is connected to each other VIA VPN.
I unfortunately cannot do server upgrade all at once, and tackling this project in 2 phases (3 sites per phase)

Phase 1 is complete this it the current setup with regards to Exchange and AD.
SITE 1: (Bridgehead Site) 2 x Server 2012 R2 AD servers, 1 Server 2003 AD Server, 1 Exchange Server 2003 and 1 Exchange Server 2007
SITE 2: 2 x Server 2012 R2 AD servers, 1 x Exchange Server 2007.
SITE 3: 2 x Server 2012 R2 AD servers, 1 x Exchange Server 2007.  
SITE 4: (1st Exchange 2007 server Deployed) 2 x Server 2012 R2 AD servers, 1 x Exchange Server 2007.
SITE 5: 1 x Server 2003 AD server and 1 Exchange Server 2003

Site 1 is HQ and also site where external inbound and out email transport occurs to and from the Exchange 2003 server.

When there is any issues at SITE 4, mail transport for the entire college stops and queues, both internal inter exchange and external stops flowing till issues are resolved at site 4.
To me its seems as if the entire college email system is solely reliant on SITE 4 for Inter-site and external mail transport.  Main site should not be site 4, it must be SITE 1, but seems like all email seems to be relaying to this site and from this site to Site 1  and out.

I've read that this SITE 4 dependency issue might have something to do about it being the first Exchange 2007 Org site.…
we just moved to Cisco AMP for email. It has been a nightmare of epic proportions. I would like to get some feedback as to others experience. We had reseller do install. We have had email being blocked due to new IP address of the Cisco appliance. We have had email disappearing into the either without a trace.  Some times it shows hitting the Cisco appliance but not Office 365 and the other way around. But the hardest part is the email that disappears without a trace. Or email that is kicked back to the sender but no notice on our end. Had reseller do the install.

Looking for feedback- we were almost going with VIPRES email filtering solution as it did the same thing with attachments and links but had some great features like stripping and email with too large of an attachment and sending the email on with a ling for you do download the attachment from VIPRE.  The GUI for Cisco is cumbersome and not very intuitive. VIPRE's was very intuitive.

Out intent was to get the Firepower/AMP for Email and AMP for Endpoint all installed- Firepower went without a problem but the email piece has not gone well so we are definitely not moving forward with Endpoint at this juncture.

This has been going on now for over a month- Cisco and Microsoft saying its the others fault etc.
Hi - I have an IMAP email account that was setup correctly, and all email was downloaded into Outlook as it normally does. I'm having a strange issue where I don't see any email from today or yesterday, the latest date that shows on top (sorted by newest) is Monday. The strange part about it is, that if I do a search in Outlook for something, it does show email from yesterday, but only when I search. I've checked the IMAP folder settings to make sure that "hide messages" is not set, and it isnt. I've also checked to make sure that the "TODAY" email group is not collapsed and out of view. I'm not sure where to go with this. Any ideas would be greatly appreciated!
I woud like to modify this email VBS script as follows.

1. Add BCC emails (perhaps from a ,txt file which is best)
2. Add a Reply to email as well

SubjectDate = InputBox("Date to be added to the subject:", "Enter date")
MailTo = ""
From = ""
Subject = "This is a test " & SubjectDate
Body = "Hi, This is an VBScript to send email, Regards, User."
Username = ""
Password = "passwordhere"
Email MailTo, From, Subject, Body, Username, Password

Sub Email (MailTo, From, Subject, Body, Username, Password)
 Set objMessage = CreateObject("CDO.Message")
 With objMessage
  .Subject = Subject
  .From = From
  .To = MailTo
  .TextBody = Body
 End With
 With objMessage.Configuration.Fields
      .Item("") = 2
      .Item("") = ""
      .Item("") = 1
      .Item("") = ""
      .Item("") = "passwordhere"
      .Item("") = 25
      .Item("") = False
      .Item("") = 60
	End With
	Set objFSO

We have a small SAAS application, and we want to start emailing our users a weekly email.

Can anyone recommend an approach for this? Does Mailchimp or other similar services allow you to use their API to pull the $Email, $FirstName and $EmailPreferences from your database and then send all of the emails?

Any advice would be greatly appreciated, thanks in advance.
My customer is in the middle of nowhere and our only ISP is Verizon.  I have a Smarthub in place providing the internet.   By default, Verizon blocks the outgoing smtp port 25 and will not unblock it.    I am looking for a program that I can install on a pc at the site that can act as a smtp relay service but NOT use port 25.   I need to relay the messages through that PC from a legacy iSeries.    So a webservice smtp relay program does not help me.   Anyone dealt with this before?

Outlook Email body coming through as a Text Attachment from one domain but not another.  I have a client that uses EarthLink to Host their Domain and email. They have created an email that forwards to a specific group of email addresses (within the domain)... a little over a month ago, some of the customer emails started coming through as attachment.txt instead of showing the text in the body of the email. It is NOT all senders. Just a handful.

Originally, we thought that the customers had changed something on their systems that generated the emails. To test this, I created an email using a account and added it to the FORWARD. I added the email as an additional account in Outlook and monitored the emails coming from the customer. When email comes in from the forward, the email account hosted by EarthLink, still has a blank body and an attachment.txt. The Cox email account comes in with text in the body of the email.  ALSO, note that I can go to the EarthLink Webmail site and look at the same email and there is TEXT in the body of the email. I am not sure is this is an EarthLink issue or an Outlook issue or something entirely unrelated.   Other items to note... both accounts are POP3 and each is a separate PST account but outlook opens them in the SAME profile. I have even made sure that incoming and outgoing ports are the same (IN: 995/SSL and OUT: 465/SSL)  

If this was an Outlook issue, wouldn't I experience the same issue in both accounts? If it was an …
C: drive croaked.  Finally gave up and started with a from-scratch installation of Windows 10.  All programs, OS, etc, on C:, all data on other logical drives.  This notebook has 1TB of SSD, partitioned.  So far so good.  However I managed to delete essentially all email from one Thunderbird account; the other four are fine.  Email is IMAP style.  But deleted an entire set for one account, so the server did too.  Carbonite has a complete copy of the entire Thunderbird folder (it has started over with my new installation), so looking for how to "simply" get all of the INBOX emails for one of the five accounts and import or copy them into my current TBird environment.  Spent some time with the Carbonite folk; not much help.  I did reinstall Carbonite, so I have the Carbonite Backup drive which they claim has the old file in it.  I suppose the Carbonite "drive" is just an interface to all the data that is actually at their end.  So I have about 3K email I need to recover from Carbonite, get into "new" Thunderbird.  The old version is due to be deleted soonish, so some urgency.
