Description
There are two known causes for the BA1772 PST file error:
1. PST files that have grown beyond the 2GB limit
Once a PST file grows beyond 2GB in size, the file will become corrupt and unreadable by both Outlook and ExMerge.
Microsoft article Q288283 for errors that occur when PST files exceed 2GB. http://support.microsoft.com/kb/288283 >
Microsoft article Q830336 for more details about the 2GB PST limit . http://support.microsoft.com/kb/830336 >
To overcome this ExMerge limitation, we recommend that you choose to group your mail data by month by selecting a grouping method in the Exchange tab of the software. This option will act to store mail data within separate folders for each month and overcomes the file size limit imposed on PST files (2GB) as each separate PST file will be much smaller as it only contains mail data for a specific month.
Note: You can read more about grouping of mail in the BackupAssist Help File (Help > Help > Basics > Modifying jobs > Exchange Server > Mailbox directory options)
If your PST file does grow beyond 2GB unexpectedly, you are able to retrieve some of the data by using the Microsoft Inbox Repair Tool that is available for download. This utility allows you to create a truncated copy of your PST file. The resultant copy of the file, however, will not have all of the original data because the utility will shrink the file to a size that Outlook can read (ie. less than 2GB).

2. The PST file has been opened in outlook
If any PST file created using BackupAssist is opened in Microsoft Outlook, to retrieve lost mail, we have found that subsequent backups that merge mailbox data to these PST files fail with this error.
To overcome this issue we suggest that you make a copy of the PST file to another location and open the copied PST file in Outlook to retrieve any mail data.
Note: The Exchange Mailbox Protection feature was deprecated in BackupAssist v9 and removed in BackupAssist 10. To get granular support for Exchange Server 2016, and to use the newer Exchange Granular Restore feature, we suggest upgrading to the current version of BackupAssist with the Exchange Granular add-on.
